Ericson 38 with a Pole Mounted 175 Watt Solar Panel
Recreational cruising sailboats and powerboats - Having plenty of electric power on board while cruising can make the difference between a fantastic experience and a marginal one. We know; we are cruising sailors.
If you are considering solar power for your sailboat or powerboat and want to learn more about the technology, check out our overview presentation titled Selecting the Proper Solar System for Your Boat or our Cruiser's Guide to Selecting and Sizing a Solar Charging System under our Support -> Manuals & Info section. Worksheets and tools to help size your system are also found here.
Marine solar panels are an excellent source of electrical power for the cruising sailboat or power boat. We at Custom Marine Products have developed numerous approaches to installing marine solar systems easily and cost effectively.
Our solar panels are custom made to our stringent specifications by leading and highly acclaimed PV solar panel manufacturers both in the USA and overseas. The solar cells in our panels are of the highest quality and output available and made by SunPower (USA), Bosch (German) and Qcell (German). You will see on our solar panel page that our semi-flexible solar panels have comparable performance to our line of semi-rigid and rigid high performance solar panels. This is because we use the same high performance SunPower 23.7% efficient solar cells in all of our solar panels. We use the highest efficiency cells commercially available because space on boats is at a premium, our panels deliver maximum power per square foot.
Commercial Boats and Ships - Solar power is an excellent way to reduce the carbon foot print of commercial vessels by significantly reducing the load on the onboard power generator. We have designed solar systems to supplement power to the onboard appliances. These systems often include a marine grade solar array, control electronics and highly efficient LiFePo4 battery banks. Contact us for assistance in designing and implementing a marine solar system on your ship.
Complete Marine Solar System Kits -
Figuring out the size of solar panel(s) you need and matching it up with the various accessories required for a complete high performance system can be a daunting task. That is why our engineers have developed easy to install complete solar system kits that contain everything you need for your solar system including: marine solar panels, mounting systems, solar wire, and charge controllers. We also supply high performance lithium marine batteries and inverters to round out your system. We understand many if not most solar systems on boats are unique. We are always more than happy to help you work through your thoughts and design ideas and walk you through the process. Work through as much as you can on your own (lots of support here and a boat solar power calculator tool here) and then give us a call to make sure what you've put together will meet your goals, then we can put together a quote for you with components specifically matched to your sailboat / trawler / powerboat / yacht.
We offer top-of-pole solar panel mounting systems with an optional integrated outboard motor lift crane that are cost effective, easy to install and robust enough for challenging weather conditions. We also offer mounting systems for flexible high output marine solar panels that can be mounted on a canvas bimini or curved hard top. Our solar panel mounting systems will accommodate most commercially available solar panels.

We are always researching the best products and technology.
 Semi-rigid Solar Panel
*** NEW *** Custom Marine Products has released a new series of marine solar panels. With a strong aluminum backing and very thick ETFE laminate non-skid surface, these panels can be walked on without fear of damaging the solar cells and can conform to a slightly curved surface (~5 degrees). There is no glass and no aluminum frame so these panels are considerably lighter than our rigid panels but heavier and stiffer than our semi-flexible panel series. These panels are ideal for mounting on a slightly curved rigid boat or RV surface or on our top-of-pole mounting system for lighter weight than a rigid panel. We use premium SunPower Gen III solar cells with an efficiency rating of up to 23.7%, the highest efficiency available anywhere.
