Collection: Shade Tolerant Solar Panels

See All Solar Panel Types, Dimensions, and Specifications Here

Discover Custom Marine Products' innovative semi-flexible shade-tolerant solar panels, perfect for boats facing shading challenges. Standard panels can lose over 60% efficiency when shaded, but our advanced panels, featuring high-performance SunPower Maxeon cells, excel under partial shade. The unique design includes a central or edge-mounted junction box, dividing the panel into four isolated quadrants. This allows unshaded sections to maintain full output, delivering up to three times the power of traditional panels. Ideal for mounting on biminis and dodgers, these panels are engineered to overcome shading from booms, masts, and instrument poles. Patent pending. If you only want the best, look no further! Highest output A+ grade solar cells (24.4-25.4% Efficient)!

    Customer Service and Product

    Very pleased with the performance of the rigid solar panels purchased in 2022. Customer service also has been consistently excellent both before the sale regarding product selection and after the sale regarding installation and maintenance concerns.

    Heavy Duty Panels For The Win

    Installed 1200watts of panels on my 56' commercial fishing boat in Kodiak Alaska, with salt spray and harsh winters I hardly run my genset. Installation was a breeze with using silicone to mount them. Most the boats in my family fleet have them now and we are all saving big on the fuel bill! Couldn't be happier with the purchace.

    Easy Install - Great Performance

    I worked with Tom last year to design a system for my sailboat; the dialog and information was very detailed and helpful in helping determine my system needs and completing the installation. Once ordering, the kit arrived in a timely manner and very complete. The install was very straightforward and Tom provided additional information as needed. After the install I took off on a 7 month cruise of British Columbia. The system worked perfectly during my trip. I’m very happy with the equipment and support from CMP and Tom. I highly recommend !
