Which solar energy systems are the most cost-effective?

Hello,

I am thinking about getting some solar panels to reduce my electricity costs. Does anyone have experience with this, or does anyone know how much it costs? Would be very grateful for any answer :D

Very interesting. Surely you can reduce your electricity costs, because now you receive an amount for the feed-in tariff for self-used electricity. However, solar systems only pay off after more than 10 years - until then and longer you will first have to pay off or you have the money in the bank - and it will be treated like a company for tax purposes - because you have your own power plant.
Best regards
