Buying products from the HELIOS B2 range ensures
A photovoltaic solution that is fixed to the load-bearing structure of the building
Robust and reliable, Helios B² allows the load-bearing structure to absorb the stresses thanks to its direct fixing into the building's purlins. The steel profiles are fixed using the tray's screws, eliminating the need for additional drilling. Dome Solar This reduces the risk of water infiltration by promoting optimal roof sealing.
Solar panels installed in the blink of an eye
Installation time is optimized thanks to the fact that the roofing company can attach the support brackets simultaneously with the installation of the roofing sheets. This leaves only the steel rails to be clipped in place, followed by the installation of the photovoltaic panels. Thanks to the factory-pre-mounted spacer on the rail, the starting point for installing the solar modules can be chosen (top, middle, or bottom of the generator). This represents a significant advantage.
The efficiency of your photovoltaic panels
Ventilation under the solar panels is particularly important with the Helios B² photovoltaic system. With an air gap of 121.5 to 145.5 mm between the roof and the solar panel, ventilation is guaranteed.
