Taking the step towards self-consumption is one of the best decisions you can make: you reduce your bill, gain energy independence and contribute to the planet. But there is one detail you cannot overlook: permits.
If you install your photovoltaic system without complying with the regulations, what seemed like a saving can turn into an unexpected expense in the form of a penalty.
What do you risk if you do not legalize your installation?
- Fines that hurt: between €300 and more than €6,000, depending on the municipality.
- Worst nightmare: the city council can order your solar system to be dismantled.
- Goodbye to subsidies: no subsidies or tax deductions.
- No extra income: you will not be able to receive compensation for surpluses.
- Problems when selling the house: the illegal installation reduces its value.
