Flexible Solar Panels
Highly UV resistant, but heavier than ETFE. Our standard panels have a urethane coating and last up to 10 years in the sun with minimal power degradation. The urethane coating is poured or "potted" on the solar cells and leads to a highly waterproof panel. Each individual cell is completely encapsulated by the urethane.
Slightly less UV resistance than urethane, but lighter weight. ETFE and EVA are attached to the cells via a lamination process. With high quality materials (there is a difference in the production quality of ETFE and EVA), these panels have an expected life of 5 years outside.
Panels made with these coatings will be inexpensive, but we don't recommend this coating as it tends to have a relatively short lifetime. They are the least UV resistant of any of the options.
Most UV resistant, but also the heaviest and can be challenging to mount in a streamlined manner.
The solar cells are mounted on a substrate or backing. Again, there are several options.
Very high strength to weight ratio material used in commercial building applications. Easy to create waterproof panel. Allows embedding of screw or nut into substrate.
Different thicknesses available, from 1mm to 5mm depending on requirements. Allows embedding of knurled nut into substrate. Higher density than Aluminum-Plastic-Aluminum substrate. Not waterproof without additional hardware.
Typically the strongest substrate option, but is also the heaviest. Thin and rigid.
Our standard wire has strain relief is about 12 inches long and terminates in a 3.5x1.1mm plug. This can be changed to whatever length and terminal you prefer. The wire can be embedded into the substrate to keep it waterproof or soldered on the outside of the panel. Power and ground wires can even be separated as shown below.
