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)! Want to see how shade tolerant marine solar panels work - Watch our Video!
