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!

High Performance CMP Semi-Flexible Marine Solar Panel Specifications Summary
SunPower Maxeon Series
Our SunPower Maxeon Series solar panels are made with SunPower Maxeon Gen III solar cells which have the highest energy yield (power output) of any solar cell commercially available. SunPower Maxeon cell technology uses a back contact design which maximizes the sunlight energy available to each solar cell and enables a sunlight to electric conversion efficiency of up to 25.4%. Excellent for bimini and dodger canvas mounting.
SunPower Maxeon Shade Tolerant Series
Solar panel shading is a major issue on many boats. Shading can reduce a standard panel performance by over 60%. Custom Marine Products has developed a series of semi-flexible shade tolerant solar panels that have superior performance when partially shaded by boat equipment or nearby objects. These solar panels have high performance SunPower Maxeon cells. The diagram to the left illustrates how these amazing panels work.The junction box is mounted in the center or the edge of the panel enabling the panel to have four quadrants of solar cells linked in series and isolated with diodes. If one or two quadrants are shaded, the other quadrants perform at normal output. The result is a panel that will provide up to three times the output of a standard panel when shaded. These shade tolerant panels are ideal for bimini and dodger mounting where there is boom, mast and instrument pole shading. Patent pending

What Makes Our Panels Superior
- Our Semi Flexible Shade Tolerant Panels use only SunPower Maxeon A+ Cells.
- The SunPower cells we use in these panels are 24.4% efficient.
- We use an ETFE laminate coating that won't delaminate or go milky for 10 years.
- The ETFE laminate is applied with a prismatic finish to direct sun energy into the cells.
- Panels use internal blocking diodes to isolate the quadrants unaffected by shading.
- We build 6 grommets into the panels edges for easy installation with our mounting kits.
- All panels come with 3 foot pigtails and MC4 connectors.
- Our junction boxes are filled with Non Gassing Silicon RTV for maximum electrical waterproof insulation and corrosion resistance.
