Puselastīgs saules panelis Offgridtec PCB-ETFE 50 W, 39 V

The Offgridtec 010830 PCB-ETFE 50W 39V is a semi-flexible solar panel that uses high-tech materials such as ETFE and PCB with efficient 3-busbar technology.

• 50W nominal power, bendable up to 18 degrees (lengthwise)
• Walkable, non-slip and very robust thanks to fiberglass backside
• High efficiency and 3-busbar technology

The PCB-ETFE 50W 39V from Offgridtec belongs to the latest generation of semi-flexible solar panels. The PCB-ETFE class sets new standards in stability and reliability through the composition of high-quality materials. While the front side is based on a Teflon derivative (PTFE), the back side consists 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 premium product that feels at home on boats as well as on vehicle roofs or other surfaces and combines stability, highest reliability and performance like no other.

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 handle the corresponding maximum module voltage). The PCB-ETFE 50W 39V solar panel is flexible and, compared to normal flexible solar panels, can be carefully walked on when mounted flat.

• Features of the PCB-ETFE 50W 39V solar panel
• 50W nominal power, high efficiency and 3-busbar technology
• Equipped with monocrystalline A-grade solar cells
• 1 bypass diode - minimized power loss in case of shading

Higher heat tolerance compared to TPT modules thanks to PCB backsheet, thus less prone to blistering due to poor bonding

Flexible, walkable and even when wet more slip-resistant than comparable solar modules on the market

• Easy mounting of the solar panel by gluing or using the eyelets
• Unrestrictedly suitable for saltwater, universally applicable

ETFE high-tech plastic ensures weight savings and at the same time high light transmittance of up to 96%

Easy installation thanks to pre-assembled solar cables with MC4 plug and socket

• 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 saltwater. ETFE is lighter and more light-transmissive than other plastic solutions on the market.

• Extremely stable fiberglass (PCB) carrier plate as backside

The backside made of fiberglass (PCB) makes the module significantly more stable than conventional panels with TPT backside. This construction offers the following advantages:

Prevents blistering that can occur with TPT modules due to incorrect bonding

• Tolerates higher temperatures compared to the TPT construction

Reduces the risk of cell breakage due to accidental over-bending of the panel by the user

• Technical specifications PCB-ETFE 50W 39V solar panel
• Application areas of the Offgridtec PCB-ETFE series
• Unrestrictedly usable in the marine sector
• Ideally suited for mounting on motorhomes, buses and other vehicles
• For installation on curved sheet metal roofs

Recommended for all systems where highest reliability and performance are required

Ideally suited for suspension, e.g. tents when camping, thanks to the PCB carrier layer the eyelets withstand very high mechanical loads

• About the PCB-ETFE series

This product is the result of collected experience from thousands of installations in every conceivable application area. Already 5 years ago we successfully established our first series of flexible solar panels on the market and have since 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.
