Photovoltaic systems must be checked annually to verify the efficiency and yield of the panel and the entire photovoltaic field. Generally, the panels installed have guarantees on the yield which last for 20 years. The yield must be verified in order to ask for the replacement of the panel, where this does not fall within the guaranteed parameters. In addition to verifying the production, B.F. Energy offers a 360° maintenance service. From cleaning the panels - inverters - cabins - switchboards, etc., to checking the yield and checking the state of the panels and connections with thermal chambers. Trust B.F. Energy for the periodic maintenance of your system. In addition to ordinary maintenance, we offer an emergency service for extraordinary maintenance.
