• Can we install solar panels on a fibro-cement roof?Yes, but it is recommended to perform a previous study on the standards of solidity and safety, especially if the fibro-cement contains asbestos. A reinforcement of the roof may be necessary.
• What is the size of a standard sun installation for an individual?A standard installation for a single house in Brittany varies between 15 and 25 m², producing about 3-5 kWc.
• Do solar panels work without sun?No, but they produce electricity in diffuse light, like a covered sky. However, their production remains proportional to the brightness.
• What is the maximum authorized power for a particular car installation -consum?For individuals, an installation of 9 kWc is generally the maximum power authorized to benefit from financial aid.
• Is it possible to finance a photovoltaic installation in Brittany?Yes, green loans and financing solutions are available at reduced rates to encourage the installations of the solar panel in the region.
• What is the role of an inverter in a photovoltaic installation?The inverter transforms the continuous current produced by the panels alternating the current compatible with household electrical devices.
• How long does it take to create a sunny installation in Brittany?Depending on the size of the installation and the aid obtained, the profitability has reached between 10 and 15 years for an installation of cars -consuma with surplus resale.
• Can we connect a solar installation to a rescue generator?Yes, hybrid systems can be set to combine solar panels and generators, providing supply even in the event of a current interruption.
• Should you ensure your sun installation?Yes, it is advisable to eliminate specific insurance to cover possible damage related to bad weather, theft or vandalism.
