• The system is installed on the roof of a factory for photovoltaic inverters in Helsinki. The primary purpose of the photovoltaic system is to provide natural conditions for the test use of  inverters. The system allows the connection of solar modules to inverters in different sets according to the respective test requirements. The installation system used is simple and light, enabling quick installation on the bitumen roof without breaking the roof surface.
