Why SunPower?
Unparalleled Efficiency
SunPower panels make your limited deck and rooftop space count by using their prime cells, the highest efficiency silicon cells on the market.
- 22–25% efficiency levels mean higher power production than standard silicon panels of the same area.
- SunPower panels are shade resistant as each cell operates independently.
- SunPower cells perform better than standard silicon cells in extremes of temperature and deliver excellent low light level performance
- Re-charging times are faster with SunPower panels as energy conversion levels are higher so you can depend on quicker battery replenishment whilst enjoying your leisure time.
- Flexible panel surface means that contours can be followed to help you maximize space on board
High Quality
Only SunPower branded flexible panels are built in the same factories as SunPower industry-leading residential solar panels.
- The SunPower Maxeon Solar Cell is the only solar cell built on a copper foundation. This makes these back contact cells resistant to cracking and corrosion when flexed or exposed to a moist environment unlike conventional cells which can fail or lose power.
- The substrate is constructed of high grade lightweight polymer materials designed to withstand high UV exposure.
- Stainless steel grommets and industry standard electrical connectors.
- Highly automated production ensures consistent quality.
- Reliable Manufacturer’s warranty backed by Total the world’s 4th largest energy company.

Getting Up and Running
Each panel is supplied with out put cables and waterproof connectors that simply click to mating connectors. Sets of cables are available to order in 5m and 10m lengths.
An in-line diode for the + connector is available for use in multiple panel connections. Panels can be connected in parallel or series as shown in the relevant diagram on the support page.
Caution: Ensure maximum input voltage level of the regulator selected is observed to avoid damage to regulators. It is not recommended to connect panels in series (to increase voltage) when charging 12V batteries.
