Offgridtec ETFE-AL 120w 20v semi flexible solar panel

The semi-flexible ETFE-AL 120W V2 solar panel from Offgridtec (MPN 018430) is based on an innovative material composition (aluminum-ETFE) and is equipped with highly efficient monocrystalline cells. The output voltage is 18V DC, making it highly versatile for various applications. Additionally, it is walkable and significantly more slip-resistant than its predecessors, making it the perfect choice for marine and mobile applications. The power is provided by state-of-the-art solar cells that feature an impressive cell efficiency due to the latest technology and stand out from the competition with low power degradation values.

This is the new and improved version of the popular ETFE-AL 120W solar panel (3-01-011050). The new version features enhanced solar cells and 11 busbars, leading to improved light absorption and reduced impact from partial shading.

About the 120W ETFE AL V2 Solar Panel

• 2 overlapping ETFE layers
• Improved slip resistance
• Higher long-term yields due to better light transmission
• Durable ETFE front offers protection against hail
• Resistant to saltwater
• Operates with 11-busbar technology
• 2 bypass diodes - minimized power loss in shaded conditions
• Integrated AL backsheet

ETFE Layers

The front side of the module features 2 overlapping ETFE layers, ensuring solid protection for the internal cells and maintaining high light output over many years. Thanks to a new structure of the outermost layer, slip resistance has been significantly improved, making the module easy to walk on. Over the long term, better light transmission and significantly less clouding of the transparent ETFE front layers result in higher yields compared to conventional solar panels with different front coatings. The durable ETFE front provides strong protection against hail and makes the module completely resistant to saltwater. The integrated AL backsheet prevents cell cracks caused by improper handling or installation. This series is equipped with premium solar cells that offer a high cell efficiency of 22.3%.

11 Busbar Technology

Power management is handled by 11 busbars. This advanced technology distributes electricity through eleven electrical conductors (busbars). This allows for reliable power transmission even at high currents while minimizing heat loss. The efficient distribution of electricity ensures solid performance of the solar panels, leading to improved overall efficiency and higher yields.

Monocrystalline Solar Cells

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 characterized by their uniform structure, which allows for more efficient movement of charge carriers. This results in better performance, especially in limited space conditions, as monocrystalline modules offer higher power density.
