New-generation plug-and-play solar panels have an average power output of around 400 watt-peak* (Wp) each, which is close to a standard photovoltaic module with a power output of between 375 and 500 Wp. Read also: MAP: How long before home solar panels cover costs in France?
The amount saved does of course depend on how much you are paying for electricity now, and how much sunshine your solar panels are able to use. This depends significantly on location; for example, in one year, an average solar panel will produce more electricity in Marseille (620 kWh) than in Paris (430 kWh).
