Shade Tolerant Design Solar Panels by CMPower

Our New 4 Quadrant Design

The diagram along side illustrates how these amazing panels work. Instead of the normal 2 quadrant design we use a new split cell design allowing the panel to have four quadrants of solar cells linked in series and isolated with inner panel blocking diodes. If one or two quadrants are shaded, the other quadrants perform at normal output. This can increase shaded panel output by 3 times that of a standard shaded panel.

Shade Tolerant Solar Panels

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!
