Offgridtec PCB-ETFE 50W 39V Semi-Flexible Solar Panel

The pcb-etfe 50w 39v from Offgridtec (mpn 3-01-010830) belongs to the latest generation, semi-flexible solar panels. The pcb-etfe class sets new standards in stability and reliability by the composition of highest quality materials. While the front side is based on the Teflon derivative (ptfe), the back side is made of fiberglass (pcb). The module works with modern 3-busbar technology. These and other quality features make the pcb-etfe 50w from Offgridtec a universally applicable product of the upper class that feels just as comfortable on boats as on vehicle roofs or other surfaces and combines stability, maximum reliability and performance like no other.

Thanks to its high operating voltage of 39v, it is ideally suited for 24v systems or 12v systems (12v only in conjunction with mppt charge controllers that can handle a corresponding maximum module voltage). The pcb-etfe 50w 12v solar cell is flexible and, compared to normal flexible solar cells, can also be carefully walked on when mounted level.

Technical characteristics pcb-etfe 50w 39v solar panel

• 50W rated power, high efficiency and 3-busbar technology
• Equipped with monocrystalline A-grade solar cells
• Higher heat tolerance compared to TPT modules thanks to PCB backsheet, therefore less susceptible to blistering due to poor bonding
• Flexible, walkable and even more slip-resistant than comparable solar modules on the market, even when wet
• Easy installation of the solar panel by gluing or using the eyelets
• Suitable for use in salt water without restrictions, universally applicable
• ETFE high-tech plastic ensures weight savings and high light transmission of max. 96%
• Easy installation thanks to pre-assembled solar cable with MC4 plug and socket
• Proven Offgridtec quality: manufactured exclusively from premium raw materials of the highest quality level

etfe high-tech plastic on the front side

The front side of the solar panel is covered with a high-tech plastic layer based on ethylene-tetrafluoroethylene copolymer etfe - a teflon derivative (ptfe) - and offers excellent protection against harmful environmental influences and is also suitable for use in salt water. etfe is lighter and at the same time more translucent than other plastic solutions on the market.

Extremely stable fiberglass (pcb) backing plate as backside

The fiberglass (pcb) backing makes the module much more stable than conventional panels with tpt backing. This structure offers you the following advantages:

• prevents bubbling that can occur with tpt modules due to incorrect bonding
• tolerates higher temperatures compared to tpt assembly
• reduces the risk of cell breakage due to accidental over-bending of the panel by the user
