Offgridtec ETFE-AL 60W V2 semi-flexible 18.2V solar panel

The semi-flexible ETFE-AL 60W V2 solar panel from Offgridtec is based on a pioneering material composition (aluminium-ETFE) and is equipped with highly effective mono cells.

• Works with 11-busbar technology
• Integrated ALU backsheet minimises the risk of cell cracks

This is the new and improved version of the popular ETFE-AL 60W solar panel. 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 60W ETFE AL V2 solar module
• 2 superimposed ETFE layers
• Improved slip resistance
• Long-term higher yields due to better light transmission
• Solid ETFE front offers protection against hail
• Resistant to salt water
• Integrated AL backsheet
• ETFE layers

On the front of the module, 2 superimposed ETFE layers provide solid protection for the internal cells and high light yield over many years. Thanks to a new structure of the outermost layer, slip resistance has been significantly improved and the module can be walked on without any problems. In the long term, higher yields are achieved through 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 offers strong protection against hail and makes the module absolutely resistant to salt water. The integrated AL backsheet makes the occurrence of cell cracks due to incorrect handling or installation almost impossible. The series is equipped with the best solar cells, which offer a high cell efficiency of 22.3 percent.

• 11 busbar technology

The current management is handled by 11 busbars. In this advanced technology, current management takes place via eleven electrical conductor tracks (busbars). This enables reliable throughput, even at high currents, while minimising heat losses. The efficient distribution of the current ensures solid performance of the solar modules, leading to improved overall efficiency and higher yields.

• Monocrystalline modules

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