PCB-ETFE 50W 39V Off-Grid Semi-Flexible Solar Panel
The PCB-ETFE 50W 39V semi-flexible solar panel is designed to deliver outstanding reliability even in the most demanding applications. Featuring a highly transparent ETFE front layer and a robust fiberglass (PCB) backing, it offers superior durability, long-term performance, and greater resistance compared to conventional semi-flexible solar panels.
The module works with modern 3-busbar technology. These and other quality features make the PCB-ETFE 50W from a universally applicable, high-end product that is just as at home on boats as it is on vehicle roofs or other surfaces, combining unparalleled stability, maximum reliability, and performance.
Thanks to its high operating voltage of 39.6V, it is ideal for 24V systems or 12V systems (12V only in conjunction with MPPT charge controllers that can process a corresponding maximum module voltage). The PCB-ETFE 50W 39V solar cell is flexible and, compared to normal flexible solar cells, can also be walked on carefully when mounted on a flat surface.
• 50W nominal power, high efficiency, and 3-busbar technology
• Equipped with monocrystalline A-grade solar cells
• 1 bypass diode - minimized power loss in shaded conditions
• Higher heat tolerance compared to TPT modules thanks to PCB backsheet, making it less susceptible to blistering due to poor adhesion
• 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 ring eyelets
• Unrestricted saltwater compatibility, universally applicable
• ETFE high-tech plastic ensures weight savings and high light transmission of up to 96%
• Easy installation thanks to pre-assembled solar cables with MC4 plug and socket
• Proven Offgridtec quality: manufactured exclusively from premium raw materials of the highest quality
• 12-month warranty – information on the warranty conditions can be found here
ETFE high-tech plastic on the front
The front of the solar panel is covered with a high-tech plastic layer based on ethylene tetrafluoroethylene copolymer ETFE – a Teflon derivative (PTFE) – which offers excellent protection against harmful environmental influences and is also suitable for use in salt water. ETFE is lighter and more translucent than other plastic solutions on the market.
Extremely stable fiberglass (PCB) backing plate
The fiberglass (PCB) backing makes the module significantly more stable than conventional panels with TPT backing.
This design offers the following advantages:
• Prevents blistering, which can occur with TPT modules due to incorrect bonding
• Withstands higher temperatures compared to TPT construction
• Reduces the risk of cell breakage due to accidental overbending of the panel by the user
Areas of application for the Offgridtec PCB-ETFE series
• Unrestricted use in the marine sector
• Ideally suited for installation on motorhomes, buses, and other vehicles
• For installation on rounded sheet metal roofs
• Recommended for all systems that require maximum reliability and performance
• Ideally suited for suspension, e.g., tents when camping; thanks to the PCB carrier layer, the ring eyes can withstand even very high mechanical loads
About the PCB-ETFE series
This product is the result of experience gained from thousands of installations in every conceivable area of application. We successfully launched our first series of flexible solar cells on the market five years ago and have been continuously developing and optimizing our modules ever since.
