Sunpower Monocrystalline Flexible Solar Panels

Made with SunPower’s highest power Gen II back contact cells, SunPower’s flexible panels deliver the highest power output and the highest charging capacity in their product class. SunPower‘s panels are constructed with top-grade, light-weight polymer materials, allowing for easy transport, installation and panel flexing up to 30 degrees.

The SunPower Maxeon® Solar Cell is the only cell built on a solid copper foundation. Flexible panels made with SunPower cells are resistant to power loss via cracking and corrosion, unlike conventional cells, which are much more likely to lose power when bent or subjected to a moist environment. SunPower flexible panels are the #1 choice for customers due of the combination of high power and cell ruggedness.

The panel can be installed with adhesives and/or by use of the 4 x 316 stainless steel grommets in the panel. The panels have standard quick-connect cables. An easy-to-follow installation guide is provided with each panel.

This 50 Watt flexible panel is perfect for smaller boats or to trickle charge your batteries when not aboard.

Maximum System Voltage 45V - Each flexible solar panel comes with MC4 male and female connectors that can connect easily to solar compatible devices in either series (up to 2 panels) or parallel

Sunpower recomends the use of Blocking diodes between parallel panels.

Sunpower Panels come with a 5 Year Power and 2 Year Product Warranty with no saltwater exclusion.
