Offgridtec® etfe-al 160w 12v semi flexible solar panel

The semi-flexible ETFE-AL 160W V2 solar panel from Offgridtec (MPN 018435) is based on a pioneering material composition (aluminium-ETFE) and is equipped with highly efficient mono cells. The output voltage is 18V DC, which makes it very interesting for a variety of application scenarios. It can also be walked on and is significantly more slip-resistant than its predecessors, making it the perfect choice for marine and mobile applications. The power is supplied by state-of-the-art solar cells which, thanks to the latest technology, have a remarkable cell efficiency and also stand out from the crowd thanks to their low power degradation values.
This is the new and improved version of the popular ETFE-AL 160W solar panel (3-01-012500). In the new version, the solar modules are equipped with both improved solar cells and 11 busbars, which leads to improved light absorption and reduces the effect of partial shading.

About the 160W ETFE AL V2 solar module

• 2 superimposed ETFE layers
• improved slip inhibition
• higher yields in the long term due to better light transmission
• solid ETFE front offers protection against hail
• resistant to salt water
• Works with 11-busbar technology
• integrated AL backsheet minimises risk of cell cracking

ETFE layers

On the front of the module, 2 superimposed ETFE layers ensure solid protection of the internal cells and a high light yield over many years. Thanks to a new structure of the outermost layer, the slip resistance has been significantly improved and the module can be walked on without any problems. In the long term, higher yields are achieved thanks to better light transmission and significantly less clouding of the transparent ETFE front layers compared to conventional solar modules with different front coatings. The solid ETFE front provides strong protection against hail and makes the module absolutely resistant to salt water. The integrated AL backsheet virtually eliminates the risk of cell cracks caused by incorrect handling or installation. The series is fitted with the best solar cells, which offer a high cell efficiency of 22.3 per cent.

11 Busbar technology

Power management is handled by 11 busbars. With this advanced technology, the current is managed via eleven electrical conductor paths (busbars). This enables reliable throughput, even at high current levels, while minimising heat losses. The efficient distribution of the current ensures a solid performance of the solar modules, resulting in improved overall efficiency and higher yields.

Monocrystalline modules

Monocrystalline solar modules are an advanced form of photovoltaic module made from a single crystal lattice. This crystalline structure enables higher efficiency in the conversion of sunlight into electrical energy compared to other types of solar modules. The monocrystalline cells are characterised by their uniform structure, which enables a more efficient movement of the charge carriers. This leads to better performance, especially in situations where space is limited, as monocrystalline modules have a higher power density.
