INCA SOLAR mounting rails for Onduline roof systems continue to be an aesthetic, ergonomic, and cost-effective roof installation system. In the installation of solar energy systems on Ondüline roofs, INCA SOLAR L brackets are used by being planted on rafters. These brackets allow the solar energy systems to be raised to the desired height on the rafters. Special planting screws are used to place the INCA SOLAR L brackets. These screws are thrown into the rafters of the roof and hold strongly and can carry the weight of the solar energy systems. The use of holders and INCA SOLAR easy nuts in the assembly stage shortens the installation time and saves time. Our rails are designed in accordance with the panel load as well as wind and snow load capacity and have undergone static tests.
