Sailboat Solar Panels
We are cruising sailors and our specialty is all things solar for sailors, including lithium batteries.
If you have any questions at all, say on how to mount panels or want to go over your power consumption calculations please call any time at 248 705-8337.
How much solar do I need? I just need panels Just browsing and learning Tell me about lithium batteries
We provide all sizes of rigid, semi-rigid walk on and semi-flexible marine solar panels for built specifically for sailboats. Our innovative solar panel mounting hardware is robust and we use, have used, and have tested all our mounting systems, solar panels, solar controllers, and lithium batteries on our own "testing" vessel as we cruise for six weeks or so each summer on our Ericson 38. It's tough work but somebody has to do it and we figure may as well be us.
For a sailboat, space is at a premium so having the highest output solar cells available is key. We primarily use SunPower's highest grade A+ 23.7% efficient monocrystalline solar cells. They still put out significant power even when partially shaded. Our panels have essential blocking and bypass diodes built in and silicon-filled junction boxes. Our rigid solar panels have strong anodized aluminum frames and marine grade sealants. Our semi-flexible and semi-rigid solar panels average the same output per area as our rigid panels. They're made with ETFE laminates that won't deteriorate, degrade or delaminate in heavy sun.

High Performance CMP Sailboat Solar Panel Specifications Summary
A Few Facts About Sailboat Solar Panels
Panel Type - There are many articles written on the two types of solar panels also referred to as photovoltaic panels (PV) ; monocrystalline and polycrystalline. Monocrystalline panels are made up of single crystal silicon wafers. Polycrystalline panels are made using silicon wafers that have a multiple crystalline structure. There are pros and cons to each type of panel. Monocrystalline panels have a higher output per square inch in direct sun. They can be sensitive to shading and output may degrade faster on cloudy days. Polycrystalline panels tend to have a lower output per square inch in direct sun but are not as sensitive to being shaded. It is important to note that today's newer high quality polycrystalline panels perform within 5% of monocrystalline panels in full sun. The premium monocrystalline SunPower cells used in our marine solar panels provide the best all around performance of any solar cells on the market.
Panel Solar Cell Quality - Because boats have a relatively confined space, maximum power output per surface area is very important. The quality of the solar cells used in solar panels is a key factor in determining the panel output. Solar cells are passed under a standard light source and graded as to their output (1-10). Grades are grouped into classes. Class A (and A+) solar cells are grades 8-10, Class B solar cells are grades 4-7 and so on. Solar cell quality follows a bell curve; there are many more Class B solar cells than Class A. We at CMP specify only the best Class A-9 (A+) solar cells for use in our panels which results in a panel efficiency of 16-24%. Less expensive Class B and C panels are often used on land based solar farms where space is not an issue. Though a bit more expensive, our customers have reported that our solar panels often outperform the performance rating on the panel label.

Average 5 Sun Hours in a Day
The Importance of Solar Cell Quality - Not All 100 Watt Solar Panels Are Created Equal -
High quality high performance solar cells will produce more power at various sun angles than lower quality solar cells; up to 30% more power. An important consideration in determining how much solar power you need is how many watt hours or amp hours of power you can expect to generate in a 24 hour period. Let's say you cruise in an area that receives an average of 5 hours of full sun a day. The average is computed based on the seasonal sun angle and the sun angle from morning through evening. A 100 watt solar panel with average efficiency solar cells may produce 100 watts x 5 hours or 500 watt hours of power in a day. At 13 volts that's about 38 amp hours in a day. A 100 watt panel with high efficiency solar cells will produce up to 30% more power in a 24 hour period or 100 watts x 6.5 effective hours or 650 watt hours of power in a day. At 13 volts, that's about 50 amp hours in a day. 38 amp hours vs. 50 amp hours in a day is significant on a boat. Add more panels in the mix, say 400 watts and we see 152 amp hours vs.200 amp hours, a difference of 48 amp hours. This simple analysis does not take into consideration the impact of clouds or shading both of which will make the disparity even greater. Clearly, the higher the quality of the solar cells the more power produced over time.
Panel Shape - The largest market for solar panels is commercial applications where many many panels are mounted on a roof or in a field. These panels are usually rectangular in shape often twice as long as wide. This shape is often not ideal for marine application. Often a more square shape is preferable, especially for pole mounting.
Marine Grade - It's no secret that the marine environment, especially salt water, can be tough on equipment. To withstand the rigors of the marine environment, solar panels should have strong stout anodized aluminum framing, should be well sealed and waterproof, and have the electrical box on the back of the panel encased in an inert non-corrosive waterproof material (like silicone) to protect the electronic components.
Quality marine grade solar panels are designed with bypass diodes to significantly reduce the impact of shading that so often occurs on a boat.
Choosing the right panel for your needs will require study and/or discussion with PV panel experts. Our staff at Custom Marine Products are ready to help you design the best solar system for your marine needs. Contact us via email or phone for a free consultation.

Solar Tax Incentive - As long as there is a head, galley, and at least a bunk onboard and your boat is docked in the United States, your vessel qualifies. This Federal tax credit is a 30% credit on all qualified expenses to purchase and install solar panels and a solar system (including any installation charges), with no maximum limit for equipment placed in service after 2008. Plus you may have tax credits in your state.
How much solar power do you need on your boat?
The amount of power needed while cruising depends on many factors including the energy used by appliances and lighting, the output of the engine alternator, the climate and the length of time away from shore power. These and other factors will determine the amount of solar power and thus size of the solar panel(s) you may need for your boat.

How do I mount solar panels to my bimini or dodger?
Bolt-on System - Customers have found that using our canvas bolt-on kit works well for mounting our semi-flexible marine solar panels directly to their boat's bimini or dodger canvas. The kit includes a vinyl disk to be adhered to the underside of the canvas, fender washers to secure the bolt to the canvas, a bolt and nut to tighten the washers to the canvas and an acorn nut to secure the solar panel to the bolt. The kit includes 4 or 6 sets of attachment hardware depending on the solar panel. All metal components are stainless steel.
Magnet Mounting System - This mounting system does not require holes in the canvas. We have found very high power rare earth magnets (up to 20 pound pull strength per magnet) are ideal for temporary mounting of our flexible solar panels on a boat's canvas bimini or dodger. Our rare earth magnet kit includes 8 or 12 magnets and adhesive to attach the magnets to the upper side of the solar panel.
What are the best marine solar panels?
The best marine solar panels have five essential components:
1. Sunpower cells - even if a cell is partially shaded they still produce power. Sunpower's A+ grade cells (Maxxeon) are among the best available putting out up to 23.7% efficiency.
2. Potted (silicone filled) junction boxes - so saltwater cannot corrode the electronics.
3. Easily mountable, either semi-flexible or rigid panels with stout anodized aluminum framing, depending on the application.
4. A+ grade solar cell quality. Cheaper panels will have cheaper, less efficient cells. Space is always at a premium in marine applications so the highest efficiency cells available are imperative. Highly efficient cells produce considerably more power at lower sun angles than lower grade cells.
5. Have bypass diodes to significantly reduce the impact of shading that often occurs on boats.
How much more power can I get from a pole mounted solar panel vs a flat mount?
Our top-of-pole mounting system enables manual tracking of the sun position for maximum panel performance and keeps the panel up and out of the way of the rigging. Rotating or tilting the panel just several times a day to obtain an optimum sun angle can increase the panel output by as much as 30%. This means more power from a smaller panel; ideal for the marine environment where space is limited. Our systems are easy to install and remove. In severe weather, simply tilt the panel horizontally or remove one bolt (or quick release pin), unplug two wires and lift the panel off the pole.
What is the difference between a cheap marine solar panel and an expensive marine solar panel?
High quality high performance solar cells will produce more power at various sun angles than lower quality solar cells; up to 30% more power. An important consideration in determining how much solar power you need is how many watt hours or amp hours of power you can expect to generate in a 24 hour period. Let's say you cruise in an area that receives an average of 5 hours of full sun a day. The average is computed based on the seasonal sun angle and the sun angle from morning through evening. A 100 watt solar panel with average efficiency solar cells may produce 100 watts x 5 hours or 500 watt hours of power in a day. At 13 volts that's about 38 amp hours in a day. A 100 watt panel with high efficiency solar cells will produce up to 30% more power in a day or 100 watts x 6.5 effective hours or 650 watt hours of power in a day. At 13 volts, that's about 50 amp hours in a day. 38 amp hours vs. 50 amp hours in a day is significant on a boat. Add more panels in the mix, say 400 watts and we see 152 amp hours vs.200 amp hours, a difference of 48 amp hours. This simple analysis does not take into consideration the impact of clouds or shading both of which will make the disparity even greater. Clearly, the higher the quality of the solar cells the more power produced over time.
