Offgridtec PCB-ETFE 50W 39V semi-flexible solar panel

The PCB-ETFE 50W 39V from Offgridtec (MPN 3-01-010830) is part of the latest generation of semi-flexible solar panels. The PCB-ETFE series sets entirely new standards for stability and reliability thanks to its composition of the highest-quality materials. While the front side is based on a Teflon derivative (PTFE), the back side consists of fiberglass (PCB). The module utilizes modern 3-busbar technology. This and other quality features make the PCB-ETFE 50W from Offgridtec a versatile, top-of-the-line product that performs just as well on boats as it does on vehicle roofs or other surfaces, and combines stability, maximum reliability, and performance like no other.

Thanks to its high operating voltage of 39.6V, it is ideally suited for 24V systems or 12V systems (12V only when used with MPPT charge controllers capable of handling the corresponding maximum module voltage). The PCB-ETFE 50W 39V solar cell is flexible and, when mounted on a flat surface, can even be walked on carefully—unlike standard flexible solar cells.

Features of the PCB-ETFE 50W 39V solar panel

• 50W rated power, high efficiency, and 3-busbar technology
• Equipped with monocrystalline A-grade solar cells
• 1 bypass diode—minimized power loss during shading
• Higher heat tolerance compared to TPT modules thanks to the PCB backsheet, making it less prone to blistering due to poor adhesion
• Flexible, walkable, and even more slip-resistant when wet than comparable solar modules on the market
• Easy installation of the solar panel via adhesive bonding or using the ring eyelets
• Unrestricted saltwater compatibility, universally applicable
• ETFE high-tech plastic ensures weight savings while providing high light transmittance of up to 96%
• Easy installation thanks to pre-assembled solar cables with MC4 plugs and sockets
• Proven Offgridtec quality: manufactured exclusively from premium raw materials of the highest quality
• 12-month warranty—you can find information on the warranty terms here

ETFE high-tech plastic on the front side

The front of the solar panel is covered with a high-tech plastic layer based on ethylene-tetrafluoroethylene copolymer (ETFE)—a Teflon (PTFE) derivative—which offers excellent protection against harmful environmental influences and is also suitable for use in saltwater. ETFE is lighter and more translucent than other plastic solutions on the market.

Extremely Sturdy Fiberglass (PCB) Backing Plate

The fiberglass (PCB) backing makes the module significantly more stable than conventional panels with a TPT backing. This design offers you the following advantages:

• Prevents blistering, which can occur in TPT modules due to improper bonding
• Withstands higher temperatures compared to the TPT construction
• Reduces the risk of cell breakage caused by the user accidentally bending the panel too far
