Semi-Flexible Marine Solar Panels with A+ SunPower Solar Cells

Our SunPower monocrystalline cell and PERC monocrystalline cell flexible 55-145 watt high efficiency solar panels are manufactured to our specifications by highly acclaimed solar panel manufacturers. 
Unique features of our semi-flexible marine grade panels include the following:
  • Quality materials - We use impermeable ETFE laminates that will not cloud of degrade with exposure to intense UV light. 
  • High Performance when partially shaded: We have blocking diodes throughout the panels to shut off non-producing cells automatically and draw power from producing cells. Our cells are A+ grade cells that continue to produce power even when partially shaded.
  • Grade A+ SunPower solar cells -  The panels are comparable in performance to our rigid panels. They produce high power at low sun angles and when partially shaded - ideal for cruising sailboats and all marine applications needing maximum output from limited space.
  • Mounting flexibility - Flexible panels will contour and flex against curved surfaces with a maximum bending radius of 30 degrees, ideal for mounting on a bimini top or a curved deck surface. 
  • Mounting options - Each panel can be affixed by high bond tape, snap, magnetic or screw mounting. Our screw mounting system has become the most popular method of attaching solar panels to canvas biminis and dodgers. Grommets are an added bonus for  ease-of-installation.
  • Plug and play - All panels come with industry standard waterproof MC4 connectors on 3 foot (1 meter) long pigtails.
  • Maximum output with shading - The panels are equipped with blocking and by-pass diodes so a shaded panel has minimal effect on the solar array performance.
  • Purchase options - These panels can be purchased individually or as a complete easy to install kit.  
  • Durable -  Although not recommended, the panels can be lightly stepped on.

High Performance CMP 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 24%.
Picture

SunPower Maxeon Shade Tolerant Series     ***** NEW *****

Picture
Picture
We have developed a semi-flexible solar panel series using SunPower Maxeon cells that has superior performance when partially shaded by boat equipment.  The junction box is mounted in the center 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.  While the center mounted junction may be a wiring issue for some installations, the panels are ideal for bimini and dodger mounting where there is boom, mast and instrument pole shading.
Picture

PERC Series (25% less cost, 1.5% less efficient)

Picture
PERC (Passivated Emitter and Rear Contact) cells are about 1.5% less efficient than Sunpower cells and cost about 25% less. These modified conventional cells produce 6 to 12 percent more energy than conventional monocrystalline solar cells. Premium PERC solar cells have an extra layer within the back side of the cell. This allows some of the sun’s rays to reflect back into the solar cell, increasing the amount of energy produced resulting in a conversion efficiency of up to 22.5%.   This enables us to provide the same high quality at a lower price per watt. Manufacture of panels with PERC cells can be automated, further reducing their cost.
