130 Watt Shade Tolerant Flexible Marine Solar Panel - Sunpower A+ Grade 24.4% Efficient Cells
High-Performance Flexible Solar Panel for Marine, RV & Off-Grid Applications
Harness premium SunPower A+ Grade 24.4% efficiency solar cells with this 130W shade-tolerant, semi-flexible solar panel. Designed to perform in both full and partial sunlight, this panel delivers consistent power output even in challenging light conditions — perfect for boats, RVs, vans, campers, or curved deck surfaces.
Unlike traditional panels, this innovative design is split into four independent quadrants. If one quadrant is shaded by a boom, mast, or obstruction, the other three continue producing full power — ensuring you never lose energy output due to partial shading. Video on them Here.
Built with anti-cracking materials and marine-grade components, it’s made to withstand saltwater, vibration, and heat while staying lightweight and easy to install.
✅ Includes mounting grommets, MC4 connectors, and blocking diodes for quick, secure setup.
📦 Ships Next Day UPS Ground from Denver or Michigan.

🎥 Shade-Tolerant Solar Technology Explained
Learn how CMP’s shade-tolerant wiring design keeps power flowing even when parts of the panel are shaded. This advanced technology ensures reliable solar performance for boats, vans, and off-grid systems, making it ideal for real-world marine conditions where shadows are unavoidable.
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.
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.
