Flexible Marine Solar Panels

See All Marine Solar Panels We Offer and Their Specs

Our SunPower monocrystalline cell and HJT/PERC monocrystalline cell flexible 55-240 watt high efficiency (up to 25.4%) solar panels are manufactured to our specifications by highly acclaimed solar panel manufacturers. 
Unique features of our 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. Compare our efficiency of up to 25.4% with others
  • 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 - Our proprietary Shade Tolerant panels are designed to provide maximum output under shading conditions like boom shading.
  • 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.

What Our Customers Have To Say

  • Doug Heath - Santa Fe, NM

    Customer Service and Product

    Very pleased with the performance of the rigid solar panels purchased in 2022. Customer service also has been consistently excellent both before the sale regarding product selection and after the sale regarding installation and maintenance concerns.

  • William Roth - Kodiak, AK

    Heavy Duty Panels For The Win

    Installed 1200watts of panels on my 56' commercial fishing boat in Kodiak Alaska, with salt spray and harsh winters I hardly run my genset. Installation was a breeze with using silicone to mount them. Most the boats in my family fleet have them now and we are all saving big on the fuel bill! Couldn't be happier with the purchace.

  • Hartwell C - Bellingham, WA

    Easy Install - Great Performance

    I worked with Tom last year to design a system for my sailboat; the dialog and information was very detailed and helpful in helping determine my system needs and completing the installation. Once ordering, the kit arrived in a timely manner and very complete. The install was very straightforward and Tom provided additional information as needed. After the install I took off on a 7 month cruise of British Columbia. The system worked perfectly during my trip. I’m very happy with the equipment and support from CMP and Tom. I highly recommend !
