Double-Layer ETFE Construction
The front of the module features two superimposed ETFE layers, providing excellent protection for the solar cells while ensuring high light transmission over many years of use.
The improved structure of the outer ETFE layer significantly increases slip resistance, making the panel walkable.
Compared with conventional coatings used on flexible solar panels, ETFE maintains its transparency more effectively over time, reducing clouding and helping preserve the panel's long-term energy output.
The durable ETFE front surface also provides strong protection against hail and is fully resistant to saltwater, making the panel particularly suitable for marine environments.
The integrated aluminum backsheet adds structural stability and helps reduce the risk of cell cracking caused by improper handling or installation.

Advanced 11-Busbar Technology
The panel uses modern 11-busbar technology, with eleven conductive tracks responsible for efficiently collecting and transferring the electrical current generated by the solar cells.
This configuration provides reliable current flow even at higher loads while helping to minimize heat-related losses.
The efficient distribution of electrical power contributes to improved module performance, higher overall efficiency, and optimized energy yield.

High-Efficiency Monocrystalline Solar Cells
Monocrystalline solar cells are manufactured using a uniform single-crystal structure, allowing sunlight to be converted into electrical energy with high efficiency.
Compared with other photovoltaic technologies, monocrystalline cells offer a higher power density, making them especially suitable for installations where available surface area is limited.
The cells used in the ETFE-AL V2 achieve an efficiency of up to 22.3%, delivering excellent performance in a compact format.
