The answer depends on where you are in France.
In France, most photovoltaic installations do not require a change of electricity meter. Existing meters, including Linky meters, are generally compatible with solar panel installations. However, it may be necessary to make some minor modifications or updates to the meter or switchboard to ensure that the photovoltaic system operates correctly and safely.
It's strongly recommended that you call in a professional solar installer or qualified electrician to assess your current electrical installation and make sure it's suitable for the addition of solar panels. They can also take care of all the necessary administrative formalities, including connecting the photovoltaic system to the electricity grid.
Please do not hesitate to contact us or your electricity supplier and local grid operator for information specific to your situation, and to ensure that you comply with all regulations in force in your area.
