Solar panels in Dixmude

Modern solar panels have a lifespan of 25 to 30 years with typically 25 years of production warranty. The inverter needs to be replaced after approximately 10 to 15 years.

Surplus electricity is injected into the grid. Depending on the country and region, you benefit from net metering, a feed-in tariff, or green certificates for compensation.

The average cost of a residential solar installation ranges from 5,000 to 12,000 euros depending on size. With local subsidies and prosumer tariffs, the payback period is typically 6 to 8 years.
