"the panels and their mounting structure performed perfectly, and should not have any doubts about the Kato Marine provided aluminum framing, or the 3M tape holding the J-extrusions"
Ian and Betsey September 7, 2021 S/V Brenna Sabre 452 Mystic CT
Hello Tom and Tom Jr.,
We are back home from our 2 week cruise in Southern New England and continued testing of our two 175W solar panels. They acted flawlessly and kept the house batteries at a full state-of-charge.
We only ran the engine for propulsion. It has now been at least 7-weeks since we disconnected from shore-power. In conclusion, you have give us the power independence we dreamed of and the outcome has been far better than we conservatively hoped for.
Our vacation also subjected the panels to some real-life equivalents of “wind tunnel testing” that should give others complete confidence in our mounting configuration.
Our vacation began with the remnants of hurricane Henri, the eye of which passed just a few miles to the east of Mystic, CT, where Brenna was docked. The wind at the dock was not severe, with the masthead only reporting gusts up to 30K due to the shelter from buildings and land. Undoubtedly, the wind speed at dock level was less, and the panels did not budge. The panels continued charging away during the daytime heaviest torrential downpour, albeit only outputting 0.2A. When the eye passed overhead, we experienced about 1-hour of sunshine and calm and the panels topped up the batteries to a full state-of-charge.
On the second week, we endured post cyclone Ida while anchored in Newport harbor. This was far more severe and quite stressful on Brenna and our nerves. Flooding from the torrential downpours has been widely reported in the national news. In addition to the rain we experienced severe wind for almost 9 hours. Early in the night we were hit by strong squalls from the N, followed by a calm spell and light breeze from the S, causing all the boats to swing 180⁰ before the next squall hit like a broadside. One of these was quite disconcerting. Brenna must have been laying against her chain as it took a while before she began to swing head to wind, and she took the brunt of the squall on the beam.
The real excitement came later, when it blew 30-40K, causing me great anxiety each time the speedometer climbed to 40K, while I monitored Brenna’s heading relative to the wind direction, and holding relative to boats to port and starboard.
The worst was when a long string of thunderstorms passed overhead or very close by, with audible cracks of thunder over the din of the wind and rain, and flashes of lightening. My wife was below at the navigation station photographing the wind speed reading as it climbed past 40K when she heard a loud roar outside. I was in the cockpit, sheltering under the dodger and glued to the wind speed instruments and Brenna’s position relative to the wind direction and to the boats to port and starboard. When she heard the roar she dropped her phone to look for me outside, fearing I might be sucked from the cockpit by a tornado. The wind peaked at 50K, stretching the anchor chain taught, creating a deafening sound and making the sea state in the harbor look frightening, as the torrential rain and spray were blown horizontally. The GPS track looks like an arrowhead, with the tip indicating the 50K blast. Fortunately, we were anchored in far enough to get protection from the harbor and did not experience any swell or hobby-horsing like some other boats anchored further out and more exposed.
You will be pleased to know that the panels and their mounting structure performed perfectly, and should not have any doubts about the Kato Marine provided aluminum framing, or the 3M tape holding the J-extrusions.
As before, once daylight arrived they began charging and finished the task shortly after the sun came out.

Ian

CMP solar panels were Brenna’s best gift in 2021, keeping her house batteries charged from the moment the solar power flowed. We never needed to use shore power again.
Even while Brenna is tucked away under her canvas winter cover on the hard, the CMP solar panels are laid out in the cockpit and keeping the house batteries fully charged, even with limited daylight hours.
I hope every other CMP customer is as pleased as we are.

"Looks like the 120W semi-rigid panel on the pole easily supports my battery bank with fridge running all day"

John Walsh, December 2021, Encore, Catalina 34
Tom, Looks like the 120W semi-rigid panel on the pole easily supports my battery bank at a full charge with fridge running all day. The short days/long nights give the batteries a big hit if I leave it on all night but it looks like the panel should bring them back up in a full day of sun, especially as the days get longer here on the Sea of Cortez. Great product Tom and excellent customer service. Mochas gracias. Best, John |
"We’ve been in winds of 35 kts thus far, and the magnets have held great."
Doug Hinschberger, November, 2020, S/Y Cassiopeia, 1997 Bavaria 46E
Tom,
We’re getting great performance from our solar panels and the magnets we used to attach them to our bimini. We’ve traveled down the Pacific Coast from Tacoma, WA to Baja California and are currently in the Sea of Cortez. We’ve been in winds of 35 kts thus far, and the magnets have held great.
I thought I’d provide some feedback on corrosion in the marine environment. We are seeing a few of the magnets begin to corrode. So far, only magnets on the top (exposed to sunlight) surface are corroding. They’re attached with double-backed tape to the panels. We have not seen any on the underside of the canvas show signs. We have some extra magnets you included in the kit, and plan to replace these.

"Tom was extremely helpful in helping analyze my electrical load needs."
Damian LaPlaca, July, 2020 Bavaria 35

I did a search for a solar panel system for my Bavaria 35 and Tom's website was the most clear and straightforward website I found. And Tom was extremely helpful in helping analyze my electrical load needs. He put together a great system of semi-flexible panels to be located on my bimini, two 145 watt panels and two 55 watt panels. They work great. I highly recommend Tom and his company, Custom Marine Products.

"Last fall you were kind enough to help sort out a solar panel and battery solution for our 36 foot sailboat"
July 10th, 2019 by Steve Holler
Hello Tom;
Last fall you were kind enough to help sort out a solar panel and battery solution for our 36 foot sailboat. We were heading to the Bahamas and after not having any solar in our first season, we were looking to improve our situation.
With your guidance we selected three flexible SunPower cell 100 watt panels that we mounted on our bimini (2) and dodger (1). We used your nut/bolt installation method for the two panels, and your earth magnets for the single unit. In hindsight, I wish I had used the magnets for the entire installation. We had absolute zero movement with the magnets and that was even after putting a layer of foil between the panels and the dodger. Taking the panels off at the end of the season only took seconds.
You also provided us with have three LiFePo4 batteries. These batteries are rated at 100 Ah, can be drawn down 95%, have a battery management system capable of 150 amp draw. You noted they have a life of 2500 cycles at 90% draw and 4500 cycles at 60% draw. You noted they would hold a draw voltage of 13 to 13.4 volts until over 95% drawn where as the traditional lead acid technology will have reduced voltage as they are drawn down.
All I can say is WOW! Last year (using Trojan golf cart batteries) we were charging our (then) 300 Ah bank almost every day with our portable gas generator. This year - we did not need it once! We could last nearly 4 plus days with the solar solution and battery combination. The batteries were regularly drawn down about 275 Ah (90+%) and they still read 13V. In fact the most difficult part of using these items - is that we had to keep track of the draw ourselves - as the battery voltage never seemed to dip!
Once we fired up our diesel engine (for example to move anchorages) we would be completely charged in three hours. The batteries would take 70-80 amps in (high output alternator) with no problem until full. We were gone four months and they operated like new the entire time.
We certainly appreciate that you were great to deal with through the whole selection process. You spent time on the phone and email to make sure we got the right combination. The products were nicely shipped to meet us at a marina in Florida and they were even delivered within 20 minutes ahead of when you promised!
We can’t be more delighted with the service, the products and the advice. It changed our cruising experience - no more stingy power monitoring or noisy generator charging!
Thanks for your help - should we need more - you will be the first and only place we call!

"your system is very straight forward and in general easy to install"
January 15, 2019 by Linda McNutt
Two 120 Watt Flexible Solar Panels
Just a quick note to let you know that the solar system I purchased from you this past summer is working well and to thank you for all your help along the way. I have attached some pictures of the system. I used Steve Boss of Boss Canvas, Clayton, NY for the canvas work. Steve did an outstanding job as can be seen in the attached pictures.
As you had mentioned, your system is very straight forward and in general easy to install. The most difficult part for me was finding somebody able to do a good job on the canvas work.
I hope the photos will be helpful to any of your other customers that may want to do something similar. Again thanks for a great product and service.
Best Regards,
Patrick & Linda McNutt

"Your advice in the past was great and we value your opinion - system is working GREAT."
June 2018 by John Amante, Catalina 42 S/V Benedica
Tom,
We bought solar panels and controller from you a few years back and the system is working GREAT. Now we are planning to add a Freezer to our boat for extended cruising down South. We currently have 2- 100 W solar panels which charge two banks of 2- 4D batteries (4 batteries total). By alternating the banks each day we have enough power to carry the load thru the night without any external power source. So the question is this… will adding the freezer be too much for the panels to carry? IF an additional panel(s) are needed how many and how many watts? Lastly how should we look to add the panels to the current system, controller or should it run thru a separate controller.
I appreciate your thoughts and recommendations. Your advice in the past was great and we value your opinion.
Regards
John Amante

John,
Great to hear from you and glad to hear your system is working well.
Here are some suggestions:
1. I'd install the freezer and see how if the solar system keeps up. You have plenty of battery power which is good. If the system can't keep up there are some options.
2. The best way to add marine solar is to use flexible panels on your bimini. From your picture, it looks like you could add a single 110 watt panel or perhaps two of our 70 watt panels parallel with the line of the boat. It will have a 130 watt and a 160 watt flexible panel available in mid August. The 130 is the same size as our 120 listed on the website. The 160 will be about 26 x 54.
3. Because these are monocrystalline cell panels and have different performance characteristic than your current panels, a separate controller would be best. Although, you have capacity for an additional 7 amps on your current controller so you could tie in a 110 or two 70 watt panels and see how it works.
4. We are experimenting with super strong rare earth magnets as an option to attach flexible panels to biminis. We aren't sure about rust prevention but are doing some tests. The advantage of this approach is that you don't have to put holes in your bimini for mounting. Another advantage is that the panels are easy to remove if you want to fold up your bimini. Just an option to think about.

Hello Tom!
We are on a mooring in Vero Beach Florida watching our battery monitor tell us we are at 13.33 V at 5:30 in the afternoon!
Just loving our solar and thinking of you.
We went to shore for warm showers wishing I had your hot water system!
Hope all is well with you and your family.

"We are so pleased that we are adding two more panels in preparation for a cruise to Mexico."
December 15, 2017 by Chris and Janet Michaelsen, Seattle, WA
In April of 2017 First Mate Marine Inc.a dealer for for Custom Marine Products, supplied and installed two CMP 110 watt semi-flexible mono Sunpower Cells along with controller, display and temp sensor. The installation was first class and we couldn't be happier with the performance. We took a two month summer cruise circumnavigating Vancouver Island and tested the system On the hook we average 110 amps a day consumption. With 4 105 amp AGC batteries that meant we used to run our genset every other day for 2-3 hours. With the addition of the solar panels we found that we were adding 55-65 amps a day to our batteries and could go 4 days without using the genset at all. We are so pleased that we are adding two more panels in preparation for a cruise to Mexico.
Hurricane Direct Hit - "After cleaning it of mud and salt water I gave it a try. It works!"
October, 2017 by Julian, Marco Island, FL - Sabre 386
Tom,
Our house and boat were in the direct line of hurricane Irma. We had sustained wind of 115 mph for 45 minutes and experienced gusts above 130mph. In preparation for the storm I moved our pole mounted panel below but left the davit "permanent" mounted panel were it was installed. The panel and all of the mounting hardware ripped away and flew down the Canal. Five days later I found it. After cleaning it of mud and salt water I gave it a try. It works! 19.90v Can't believe it but it's ready to be put back into service. Here are pictures slowing the extra hardware I used for additional support and in one picture you can see the damage to the frame.

"We are thrilled with the whole experience from design, installation, and customer service."
October 2017 by Brian and Jeanne Leckie, Baba 35 S/V Clairvoyant, Great Lakes
CMP Semi-flexible Solar Panels on a Baba 35
On our first cruise to the North Channel of Northern Lake Huron we had to run our engine in the morning and again in the afternoon to keep the batteries up. When we arrived at St. Ignace we saw many boats with a solar panel on a pole and the sailors told me Tom Trimmer from Custom Marine Products was the designer. Tom came to our boat and we discussed our options and decided on his semi flexible panels, MPPT controllers and monitors and to do a Bimini mount. Tom helped us with numerous installation questions and even arranged to meet us in the North Channel to trouble shoot an installation error. His customer service is really unbelievable; he even contacted us weeks later to check on how the panels were working. And working they are! At anchor for days we never had to start the engine to charge our batteries which run our house bank that includes our refrigerator and freezer. We are thrilled with the whole experience from design, installation, and customer service. As we continue our cruise south we tell all interested in solar to contact Tom at Custom Marine Products.
"Adding the solar panels in addition our Efoy was a real game changer."
September 2017 by Bill Stults and Barbara Busby, Tayana 42 Pilot House, SV Skye Castle, Gig Harbor, WA
160 Watt CMP Bosch Cell Solar Panels on a Tayana 42
What would be ideal is if we could run both freezers, not have to monitor battery usage closely (except for fun!) or have to plug into expensive shore power when in a marina.
We visited with Bob Dickey of First Mate Marine (Custom Marine Products northwest distributor) at the 2017 Seattle Boat Show and followed up with a get together on Skye Castle, our 42’ Tayana Pilot House trawler. We took the plunge and ordered four 160 watt Bosch solar panels with two Tracer BN series MPPT controllers. Bob walked me through the installation and I did the install myself. With the exception of running the wires through some tight spaces the installation was very easy. Pretty much plug and play.
We took a two month cruise to British Columbia this past summer. We left in late May and went as far North as the Broughton Archipelago. We experienced a fair amount of sun but also had a number of heavy overcast days. Bottom line is we did achieve our ideal. Adding the solar panels in addition our Efoy was a real game changer. We ran both freezers (at lower temperatures than ever before) and never once plugged into shore power. The Efoy did kick in now and then but we only used only 10 liters of methanol for the cruise. We realize that two freezers and keeping ice cream onboard is not essential. What it is, is a very nice luxury and for a moderate investment (in boat dollars) it’s made a happy ship even happier.

"As we watch the amps flow into our batteries, we are extremely satisfied and very grateful for the extraordinary customer service that Tom gave us."
August 2017 by Flip and Pam Mulliner, Westsail 42, SV Katura
It’s hard to find good customer service; exceptional customer service is even rarer. We found Custom Marine Products from a simple online search for solar panel controllers. We liked that the company is in Michigan, our home state. When calling for more information, the owner, Tom Trimmer, answered the phone while on his summer cruise in the North Channel area of northern Lake Huron, Ontario. Tom listened to our needs and recommended a dual output controller and monitor. Custom Marine Products was extremely easy to work with. Tom arranged for quick shipping so that we could get the controller installed before we took off for our long awaited cruise to the North Channel.
Our electrician installed the controller to interface with our other charging systems. While we were underway, we discovered that we weren’t getting any amp readings on the monitor. A call into Tom resulted in arrangements to meet up at his home port in Cheboygan, MI. He offered us a complimentary slip right next to his.
Tom tested the installation and discovered an error in our wiring. Unfortunately, one channel of the controller got zapped in the testing. Tom was quick to arrange for a new controller to be sent to us at DeTour Harbor, our next stop.
While in Cheboygan, Tom took the time to give us tips on anchorages not to miss in the North Channel. Turns out, that Tom is a legend in the North Channel. We have met several cruisers using Custom Marine Products. We even met a couple living off the grid who used solar and Custom Marine Products at their beautiful home in Hotham Bay.
As we watch the amps flow into our batteries, we are extremely satisfied and very grateful for the extraordinary customer service that Tom gave us.
So, what started out as a customer service issue has turned into a cruiser’s dream.

Thanks for recommending sheplers, they took great care of us. Very competent and fair price.
Feeling much better about charging system. On our way to deTour, looking forward to installing new controller.
Do you want me to send old controller back to you ?
It's hard to express our gratitude for everything you have done for us

May 2017 by Bruce Canavan, Mariner 31 ketch to Good Old Boat Magazine
I had been planning to add solar panels to my Mariner 31 ketch for some time but was having trouble finding a location that would work until I saw a dockmates side cockpit setup and decided right then to pull the trigger and get some ordered.
I got on Tom[‘s website (custommarineproducts.com) and was amazed at the wealth of background and technical information available. He even has spreadsheets that will allow you to easily calculate the electrical loads for both stationary and underway situations, including various losses and reductions. Using this new found knowledge (a little being a dangerous thing) I ordered two 120 watt panels & a 20 amp MPPT controller with monitor. A couple of days later I got an email back from Tom as a follow up to discuss specifics on my planned setup. He suggested using two 10 amp controllers with separate monitors to achieve better output with the side mounts and mizzen shadow. In addition, he noted several fittings I had overlooked in the original order. He re-worked the invoice to provide the additional material with minimal additional increase in cost to me.
Over the course of the next two months we maintained contact and Tom helped to resolve issues as I worked on the installation (a 13 hour round trip to San Diego where the boat is berthed slowed progress).
Tom’s service is above and beyond any I have experienced. I have been recommending him with any responses I give at the dock regarding the installation.
Great publication. Keep up the good work.

"I wanted the highest output per square foot so I went with monocrystalline panels using SunPower cells."
March 2017 by Roger Neiley, Saga 43 SoLunaMare
Three 120 watt solar panels with SunPower Cells.
I recently completed an upgrade of my previous single panel system on SoLunaMare (Saga 43 # 27) and thought I'd share just a few points without getting into a deep technical discussion.
One of the factors that required considerable research for me was determining the maximum panel size I could install without undertaking a major structural redo and with minimal shading issues. As you can see in the attached photo (before my bimini was reinstalled) positioning three 120W panels across the aft end of the cockpit worked well. For that area, fairly free of shade, I wanted the highest output per square foot so I went with monocrystalline panels using SunPower cells. These are very high quality cells that have the highest efficiency rating I could find.
I purchased the panels from Tom Trimmer at www.custommarineproducts.com. We had numerous shipping hassles with Fed Ex damage but I have to give Tom a 5 star rating for both his customer support and his knowledge of system design. Feel free to use my name as a reference if you communicate with him. The offerings were not the cheapest per watt available (nor the most costly), but in the long run, like other gear, an extra 20 or 30% up front for quality components would seem to make sense.
In preparation for long distance cruising I wanted maximum redundancy, so decided to go with a separate MPPT controller for each panel. That way, any single failure will only degrade my overall performance by 33%. I had used the Genasun 10.5A controller previously with good results, so bought two more of those and you can see the wiring layout in another of the attached photos. Each controller costs only around $100 online.
I was originally going to install an output display for each panel but space limitations and the additional wiring convinced me to simply wire inline on/off switches for each panel as shown. When desired I can easily check each panel individually by flipping just one to the On position and using our Link system to evaluate output.
Overall, I'm very happy with the investment which came in at less than $1500 total, and would encourage anyone planning an extended cruise to make solar a primary contributor to your power needs.
Best regards,
Roger Neiley

Tom,
Wanted to let you know that my solar panel mount on the pole off the stern survived TS Hermine which caused considerable damage in South Georgia. There were 3-4 boats sunk and numerous docks destroyed in our marina and the marina next door in St. Simons. We had no damage thankfully and the panel & mount withstood the 50-60 mph winds with gusts to 70 mph with no problems!
All the best,
Bob

130 Watt Solar Panels
We have two of your 130 watt monocrystalline solar panels which were installed on the bimini of our 40 foot sailboat in the Spring of 2014. They produce, or should produce, enough to power to accommodate our energy needs at anchor for an extended period of time, assuming the normal sunshine in the Northern Great Lakes. And they have done a great job of it. The panels were producing a minimum of 5 amps early in the morning and an hour before dusk and upwards of 12 amps mid-day. But something was missing--it was the regulator. We had an old PWM regulator that just wasn't allowing the panels to give to the batteries what they were capable of giving. After consulting with you, and running a few tests to make sure the problem wasn't the panels or the wiring, you recommended installing a new MPPT Tracer regulator. It wasn't cheap (very little that is good is), but it made all the difference. We haven't done any calculations, but your estimate of a 30% increase in the efficiency of the panels is spot on. Could be even higher. The package is perfect for our needs--it allows us to avoid going into port except once every ten days or so and that is mainly for provisioning. Also, just to let you know, the fridge is running and the panels/regulator is creating a positive charge to the batteries of about 8 amps.....and the sun is not yet at its peak. We now have plenty of power at anchor and don't need to plug into shore power while at the dock.
Thanks for working with us to enhance our cruising experience.

"The early results have been stellar."

120 Watt Solar Panel on a Catalina 310
Bob's post on Sailboatowners.com
Several months ago I posted a question about solar vs a generator and got plenty of opinions which is what I asked for. Decided to go the solar route but have some self-inflicted constraints such as: (1) no davits and no plans to add them and (2) have a bimini but only open it when it is raining.
This makes it difficult to dedicate the space for a large bank of panels to keep my 290AH bank of batteries full on my relatively small 31 foot boat. After much research i decided to go for maximum efficiency and install a "pointable" panel to get max amperage with the minimum size panel. The pole mount off the stern was very easy to install and it clears the bimini (which was not an accident, it took several mock-ups with cardboard to determine the minimum pole length). Also installed an MPPT controller and battery monitor. The early results have been stellar. The main power draw is refrigeration and I first double insulated the icebox, replaced the Adler Barbour compressor & evaporator with a brand new more efficient unit. Now the batteries are down about 7-8% overnight and are back to 100% by early-mid afternoon if I do not rotate the panel and before noon if I do. When rotating the panel I can double the output. See the attached pictures of the amperage. These were taken within 2 minutes of each other at 9 am this morning with the only difference being I rotated and tilted the panel to face the sun. Input from the panel and output to the batteries more than doubled.
I am writing this just to give information to others because the amount of information on single, pointable, pole mounted panels is very limited compared to the banks of panels mounted to biminis, davits and even dodgers. The panel I purchased is a Bosch 120 watt and it is supposed to be very efficient (most efficient on the market they said) according to the company I bought it from (Custom Marine Products). They said to expect 5.5 amps from the panel and the MPPT controller would then deliver 7.5 amps to the batteries. See the pictures here it has already exceeded that. If anyone wants to know where purchased or anything else let me know and I will be glad to help. So far, this looks like a great solution for my specific needs but of course is not for everyone.
Follow up question 4/27/16: I was just looking at your updated website and wondered if the new 120 watt SunPower panel is the one that I purchased? Worked very well last week on a one week trip away from the dock. Saw 8 amps coming from the panel and 11.2 amps from the MPPT controller to the batteries! New record.
Thanks,
Bob
Bob,
Yes it is the same panel as you purchased. It is powered by premium SunPower solar cells and is our best performer when matched up with an MPPT controller like you have.

"Our 100 Watt Flexible Panels Have Worked So Well We are Adding Two More."
October, 2015 by Kathy Albin, South Haven, MI Albin & Co Tug
We attached our 100 Watt panels to a heavy screen material and then attached that to our bimini frame. We can remove the panels easily for winter storage. These panels, combined with our Midnite Kid controller provide us all the power we need for cruising. We no longer have to run our generator 2-4 hours a day. We love it! We will be adding two more panels this year so we have plenty of power to heat our water with the excess solar capacity.

Six 100 Watt Semi-flexible Solar Panels
Hi there Tom,
See the attached picture for our new configuration of six 100 watt solar panels. We now have three groups of two series wired panels wired in parallel as you suggested. The performance is terrific.
Below you will find the pre-solar and solar generator hours.
2013 .. 113.5 hrs
2014 ... 103.2 hrs
2015 ... 21.0 hrs
2016 ... 18.0 hrs
Our neighbors in the North Channel anchorages were much more friendly in 2015 and 2016, even inviting us to happy hours and for dinner‼️ And we now have several unused generator filters on hand which will probably have to be offered to our non-solarized boating friends who haven't yet made the "sun power" leap. Thanks for all your support and assistance.

"These flexible panels are smokin! :-)"
June 15, 2015 by Chuck Gremel, Duncan Bay Boat Club, MI - Tartan 28
Two 50 Watt Semi-flexible Solar Panels
Once I turned off my shore power charger and used the panels to keep my battery charge up they really pumped out the power. I was reading upwards of 7 amps on the meter. They are smokin!
I ended up using stainless steel nuts/bolts/washers to attach my two 50 watt solar panels to my dodger. I also had my canvas guy punch out two inch round black leather discs I glued to the underside for added lateral strength. Next I placed a two inch nylon shoulder washer over it to further adhere the leather to the canvas and to gain vertical holding power. I sandwiched the canvas between the washers and secured them with a nut. The 10-32 bolts fit perfectly through the panel gourmets. As you can see, this made a very clean (and water tight) installation. Running the wires in the canvas channel along the support tubing worked great.
Previous email:
One question: my amp readout numbers yesterday were real low, around .5 and with a max of only 2.5 on a very sunny day. I will check again later today. The batteries were already in a fully charged state. Is the readout measuring what is being sent to the batteries which would be minimum since no addition power is required?
Chuck,
You are correct. The meter shows what the controller is putting in the batteries. When the batteries are fully charged, the controller shuts down the charge from the panels to protect the batteries from overcharging. Turn off your shore charger and see what happens.

"It generates so much power in these latitudes I am concerned that the 10 amp controller can handle it."

March 2, 2015 by Julian, Marco Island, FL - Sabre 386
Tom I have been in the islands for the last two weeks using the new solar system. It generates so much power in these latitudes I am concerned that the 10 amp controller can handle it. We have hit a maximum peak of 14 amps and regularly hit 11 amps at the highest point of the day What has impressed me the most is a 7:30 to 8:00am and again as the sun is going down we see 2 amps. Will the 10 amp controller break down under this load. Would the 20 amp be a more reliable solution? Thanks, Julian Julian, The 10 amp dual output controller will work just fine. The circuitry in that controller is built to handle the load. I have the same setup on my boat with the 10 amp controller and have seen 11-12 amps output and have had no problem for several years. Also, we have yet to have a failure with that controller. If you are concerned however, I will exchange your 10 for a 20 amp unit. Tom |

4 105 Watt Solar Panels on a Nordic Tug 32
October 5, 2014 by Bill and Jo - Green Bay, WI - Nordic Tug 32 - Dolly
We like to anchor out most of the time while cruising but found we had to run our generator at least two hours a day to charge our battery banks. The constant concern about the state of charge of our batteries and the noise of our generator running was undesirable to us. As luck would have it, we met Tom of Custom Marine Products while cruising in the North Channel of Lake Huron and he had a solution for us. Tom designed our solar system and provided us with the components. Our local yard did the installation.
Our solar panel system consists of:
4 105 watt panels wired in parallel on the pilot house roof.
2 controllers located near the battery boxes.
2 monitors installed in the pilot house overhead
This summer we only had to run our generator if we had a long string of cloudy days which was only once. What a wonderful improvement to our cruising experience. The monitors (controller remote displays) tell me exactly how the panels are performing and the state of charge in my battery banks. For anyone reading this, I suggest you contact Tom. His email is [email protected]. You will find him excellent to work with, very knowledgeable and helpful.

Our second pole with the integrated engine hoist will help our aging backs. Thank you for working with us as we get our boat ready for full time cruising.
Note: Kevin and Lynn added a second 90W solar panel with a top-of-pole mount and the optional outboard motor hoist in preparation for their new cruising life style. Kevin used our 90 degree tab sleeve with our fixed sleeve lock to effectively strengthen the pole mounting system with struts so they don't have to rely on the strength of their stern rails. See picture.

160 Watt Solar Panel, Pole Mount, on a Hunter 41
November, 2013 by Martin - Moore, Oklahoma - Hunter 42
Everything arrived in good shape. However, FedEx must be getting annoyed with Xmas season fast approaching because the exterior of the boxes were terrible. After all “Fragile” is Italian for stomp all over me.
I mocked placement on just about every possible area and settled on the aft starboard corner just on the downward slope of the transom. Pole is resting on the ball mount and I clamped the upper and lower rail mounts to the stern seat rails. The pole is quite high and somewhat unstable toward the top, That's why I am requesting an additional locking collar to connect to the steel arch.
Running the wires was a non-event! Access in the stern lazaret exposed an open 1 1/2’ PVC chase that had one ground wire running through it! We pushed the fiberglass fish through and the chase terminated right at the panel and the batteries.
We had a very clear and bright day for the installation and initial setup. So, early data is better than expected or should I say better than I expected.
Voltage was consistently 21 + and noted as high as 22.5
Amperage was consistently 9.5 and noted as high as 10.5
That's about 210 watts being produced by our 160 watt rated panel. Wow!
Once final connections were made, I shut off shore power and played with turning various things on. The center photo is with the entire 12v side TURNED ON, Bose Entertainment system (Captain Ron), freezer, refrigerator, all pumps, all lights (LED’s) and the panel was still “adding” 0.3 amps to the batteries…… The last picture shows the panels pushing 21.9 volts and adding 2.2 amps with the Fridge, freezer and stereo on….

"The panel worked brilliantly all summer."
140 Watt Solar Panel on a Freedom 32
October 28, 2013 by Henry - Wolfville, Nova Soctia - Freedom 32
Tom,
I am thinking of leaving the panel up all winter to charge the batteries. Is this considered okay? The panel will be snowed on and have alternating freeze/thaw cycles while the boat is on the hard at Mahone Bay, Nova Scotia.
By the way, the panel worked brilliantly all summer. I was fogged in for three days at Sambro and never had to start the engine once for electrical power. I used it for everything except the fridge/freezer. I even charged my Torqeedo electric outboard off of it. And my batteries are not very large -- just 240 Ah of lead acid.
If you look carefully in the photo you will see red tape near the top of the post. This is to cover the unused holes in the pole. With a wind up, the holes turned the pole into a giant flute that sounded almost exactly like a whistle buoy!
Henry,
Yes, your solar panel should be just fine staying up in the winter. Both the electronics and the panel itself are well sealed and the pole mounting system should be plenty strong to support a snow load. I would tilt in panel at a more significant angle than normal so the snow will be more likely to slide off. Face the panel south and you will have plenty of power to keep the batteries at full charge.
You are the first person to report on the musical talent of the pole. I wonder if we can claim that as a feature. :-) I'll check into offering rubber hole plugs for the pole for those not using the crane option. Thanks for the input.

I purposely waited 2 seasons to really test my solar panel installation. Everything I was told has panned out. I fully recommend CMP. The mounting system works as planned and the solar panel performs beautifully. It looks good on the boat too.

"Your pole mounting kit works great for my solar panel and for my wind generator."
May 13, 2013 by Dick - 1986 Pacific Seacraft 37, Sacramento, CA
I purchased your 140 watt solar panel kit and liked the mounting system so much I purchased another one for my wind generator. A simple sleeve adapter was used to accommodate the pole diameter of the wind generator to your 1.5"pole. I have included pictures of my installation.
Thanks for all your help and advice. Both systems are working great.

"On sunny days with panels oriented to the sun I have actually more energy than expected."
January 25, 2013 by Vladimir - Westsail 32 - Cleveland, Ohio
Tom,
Thank you for the two 90 watt solar systems! It was very convenient to have all pieces together (mechanical and electrical), mounting them was just “a piece of cake”!
I've used you solar systems for over a year now. On sunny days with the panels oriented to sun I have actually more energy than expected – up to 16 A from both panels (16x12 = 192 Wt), with clouds – 3 to 5 A. I am able to run the fridge all the time, navigational laptop, radar (with “sleep” mode). Fridge I turn off at night, but use ice packs, which are freezing at day time.
Thanks,
Vlad

"My Dual Output controller and panel are all working great and I have told several people about your excellent products! Oh yes and excellent service too!"
August 20, 2012 by Ann O - Port Townsend, Washington
Hi Tom,
I have installed the controller and the monitor. Everything is working great and I am really happy with the products. We have the solar panel functioning. however we are not able to figure out the instructions on how to set the upper and lower limit for the charger as it charges up the batteries and then of course cuts off after they are full. I actually made my living as a software engineer and I specialized in technical instruction manuals. I could make a few suggestions on a re-write of those manuals for you if you like they are mostly there they just need to be augmented with some graphics and the sequence of information changed a little. Could you explain in greater detail the steps in how to set the upper and lower limits please?
Ann, The upper and lower limits are automatically set based on the type of battery you select in the set up section. We are rewriting the instruction manual currently so your comments are certainly welcome.
Thanks,
Tom

"The CMP 90 Watt solar panel keeps our refrigeration running."
September 10, 2012 by John of Murray Time an S2 36 - Duncan Bay, Michigan
Tom,
I am pleased to report that the 90 Watt solar panel performed as expected during our four week cruise this summer. It supplied sufficient power while we were at anchor to power our refrigeration, lights and select instruments. Only on those really cloudy days did we have to run our diesel to charge the battery bank. The remote display that links to the dual battery bank solar controller is terrific. It provided me with all the information I needed to monitor my battery banks and solar panel performance.
I'll send you my panel performance data as soon as I get it summarized.
Thanks,
John

"Nice custom installation"
August 21, 2012 by Erich of Enchantress a Hunter 410 - Duncan Bay, Michigan
Tom,
This is the second boat you have done a custom installation for me. Combining the solar pole with the outboard motor hoist has really worked out well. I am impressed with the output of the 130 watt panel. Thanks for another job well done. Check out the pictures.

"The solar panel's performance exceeded my expectations."
August 19, 2012 by Tom of Melusina an Aloha 32 - Bemus Point, New York
Tom, Just returned from our three week cruise to the North Channel. We got as far as Little Current after several nights at Baie Fine. It took us a bit longer to find our way up than I anticipated but great sailing none the less. The solar panel's performance exceeded my expectations. It was out of the way and didn't interfere with sailing in 30kt+ on Lake Huron. We sailed in those squalls that hit Goderich on our way to Sarinia. Thanks again for all the info on the North Channel. The GLCC membership was money well spent for the cruising guides.
Attached is a picture of Melusina in Baie Fine.

"The custom bracket you made worked out great"
August 11, 2012 by Christian B of Cobalt Blue - Atlantic Highlands, New Jersey
Hi Tom, find some pictures attached. The custom bracket you made worked out great and the installation went smoothly. Unfortunately I have not been able to perform a meaningful long cruise that really stress test the installation with a lot of appliances running. I am still mainly working on the boat to get here ready for bigger plans and just take her our once or twice a week for day cruise. I have two battery banks with about 1200 ah capacity which are always topped off since I installed the solar panel. I intend to go cruising for one or two week in September and expect to use the radar and the electric autopilot and overnight anchor light which should give me a better idea how much engine running in need to complement the solar panel. Overall, the panel system has been serving me very well.

"I am very pleased with the panel and mast."
July 5, 2012 by Mark C - Hollywood, Florida
Hi Tom, here are a few picts. I am very pleased with the panel and mast. The installation went smoothly. Thank you for sending the bolts to replace the ones that jumped into the water.
I finally found a quick-disconnect system that I liked (heavy duty, heavy guage, etc). I purchased the Marinco male and female 120 v plug ends. I waterproofed all the internal hardware of the plugs with liquid electrician's tape and will wrap this in a Sunbrella/velcro system that I need to make. The system connects and disconnects EASY. I have a feeling that this feature will be important when it comes time to taking the panel down in heavy weather.
As you can see I felt that it was more seaworthy/ esthetic to run the cable through the mast itself as opposed to wire-tying it to the outside. This has worked great since I put a loop of cable at the base to allow for mast rotation.
Regarding your blog: I believe that this only applies if one has a "smart alternator" right? I have a "dumb" 80A one so I don't think I need to shut down the panel while the auxiliary power is on. Is this correct?
Thanks Tom for a great product,
Mark C

Mark,
Thanks for the pictures. Nice installation. I think wires inside the pole may become an option for us to offer as that is a request we are often getting. I like your installation. MC4 connectors do give you the ability to quickly disconnect the solar panel.
Regarding the conflict between your controller and your alternator - Two thoughts:
1. You will know if you have a conflict between your controller and alternator if your tach starts jumping around. This would indicate a conflict due to pulse width modulation (PWM) of the alternator and controller.
2. If you see the alternator is not charging the battery bank, it may be due to artificially high voltage from your wind and solar your alternator regulator is seeing and thus putting it in float mode.

"I am a well satisfied customer."
June 19, 2012 by Bruce of Okaga - Ontario
Hi Tom. We went out on the anchor for a day this weekend, and I played with the solar panel most of the day. Every good sailor is a "type A" and needs to be fiddling, adjusting, resetting something and I am no exception. Anyway as to results, much better than expected. We left the dock fully charged, of course, with the panel connected and producing, under a clear sky. I can adjust the pole setting from the helm as needed according to boat angle. We ran fridge, lights etc over night while on the anchor. The day on the anchor was a bright, full sun day in which I regularly adjusted tilt and angle for max output. The panel charged at 20.2V; I clocked between 5.5- 5.9 A most of the day. By 15:00 hours, the batteries were fully charged and the amps had dropped to 1.5A. I am a well satisfied customer and I took the attached photos for you.
I do have a question. After leaving the dock, I noticed that my engine Tach was bouncing around, non responsive. ( I spoke to another boater with a large panel and an electricity background who had the same issue when his batteries were fully charged and the panel operating). This effect disappeared on the return sail, when the panel and engine were actively charging. Odd, ehy?

Bruce,
I recently had a similar experience on my boat and did some research. Most high output alternators and many controllers charge batteries using a technology called Pulse Width Modulation (PWM). The Tach uses PWM to determine the alternator (and thus the engine) RPM. The two PWM sources may, at times, create an interference. Thus the sporadic readings on the Tach. The solution to this is disconnect the solar panel when the alternator is running so the controller doesn't function. This can be easily done by putting a switch in the positive wire leading from the solar panel to the controller. Alternatively, you could put in relay on this wire and wire it so the relay is open when the engine is running and closed when it is not.
Another reason to put a switch in is this. The smart regulator reads the battery charge condition and sets the output of the alternator accordingly. If the solar panel is producing power, the regulator will see the net of the battery charge and the panel output and thus prematurely put the alternator in float mode.

An Awesome System!
Two 85 Watt Panels on Poles
June 25, 2012 by Ian of BriCat - Bahamas
We cruise in the Bahamas and have always had power issues - we used to have a fairly useless Airex wind genny that never gave us enough power - so we finally decided on solar. Having done lots of research online we came to the conclusion that the best, most efficient and yet simple way to go was with Custom Marine Product's design! It was easy to set up and we flipped the switch on and got an instant 11amps! With just 2 or 3 adjustments a day, we're able to run our power thirsty fridge, our inverter and all the electronics without having to worry about power. It has transformed our lives! Other cruisers in the bay are always stopping by to admire the system, especially in the early morning or late afternoon when we can have them tilted all the way down for maximum power input. The system is outstanding value and we recommend it to everyone we meet on the water! Thanks Tom

85 Watt Solar Panel Works for Us
July 24, 2012 by Gene of SunCat - Lake Huron
I purchased the top-of-pole solar panel mount several months ago and am very pleased with it. I am using a Kyocera KC85TS 85watt panel and a controller I purchased from foster-wills.com as suggested by Custom Marine Products. This has almost eliminated my need to run the engine to charge the batteries when we are at anchor for several days at a time. The panel is easy to tilt and rotate for optimum sun angle. I also purchased the outboard motor crane. What a great concept; two functions from one pole. Nice job CMP!

Two 75 Watt Solar Panels on a Frame
August 3, 2011 by Erich of Enchantress - Lake Huron
I purchased two 75 watt solar panels from a factory outlet and couldn't figure out how to mount them. I asked Custom Marine Products for advice and they custom designed and built a mounting system that is perfect for my needs. It is above the bimini out of the way and enables me to tilt the panels for proper sun angle. Now I don't have to run the engine to charge my batteries.
