Latest generation high quality flexible monocrystalline photovoltaic solar panel S.P. ETFE 140W, innovative SunPower cells with high efficiency PV ETFE technology, can recharge 12v/24v/36v/48v batteries ideal for use on boats, campers, camping, home, etc.

The SunPower ETFE photovoltaic cell is totally different and superior to a traditional photovoltaic cell, thanks to their solid copper base and their flexibility they can guarantee extraordinary reliability and resistance, allowing you to create high-quality panels that have achieved the world record for energy efficiency.

Traditional photovoltaic cells lose power over time due to corrosion and damage to the junctions that connect the cells to each other via visible filament strips on the top of the cell. The unique design and technology of ETFE cells eliminates most causes of traditional cell failure. It will therefore be possible to enjoy exceptional performance and savings over time.

• Panel complete with cables with IP67  MC4 connectors and eyelets for fixing.

Examples of evident signs of oxidation on commercial panels with an old cell connection system with soldered wires, the thermal shock such as when the sky is cloudy and the sun suddenly comes out causes the strings that connect the cells to each other to explode, with negative effect on the panel's performance until it almost reaches zero.

SunPower technology cells, cells connected to each other without wire welding, no! oxidation!

SunPower ETFE cells more energy! with less surface coverage!
