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 walked on without hesitation when fully bonded.
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, thus less susceptible to bubble formation due to inadequate bonding
- walkable and even in wet condition more slip resistant than comparable solar modules on the market
- semi-flexible - can be bent up to a maximum of 18 degrees (lengthways)
- easy mounting of the solar panel by gluing or using the ring eyelets
- unrestrictedly suitable for salt water, universally applicable
- etfe High-Tec plastic ensures weight saving and at the same time a high light transmission of max. 96%
- Junction box with high protection class IP67
- 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 grade
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

Application areas of the Offgridtec pcb-etfe series
- can be used without restrictions in the marine sector
- best suitable for mounting on motorhome, bus and other vehicles
- for installation on rounded sheet metal roofs
- recommended for all systems where highest reliability and performance are required
- ideally suited for suspension e.g. tents when camping, due to the PCB carrier layer the ring eyelets also withstand very high mechanical loads
about the pcb-etfe series
This product is the result of accumulated experience from thousands of installations in every imaginable field of application. Already 5 years ago we were able to successfully establish our first series of flexible solar cells on the market and since then we have continuously developed and optimized our modules. With the pcb-etfe series, you benefit from this unique expertise and can look forward to a durable product that will reliably produce electricity for many years.
