With Tesla entering the market, interest in solar tiles is increasing. What should you know before you have your house roof covered with solar tiles?
Many houses, mainly older ones, lose a lot of heat because they are poorly or not insulated at all. How can you avoid this and save a lot of money?
Roof renovation can cost several 10,000 francs. You can get part of this back as a subsidy if you renovate your roof to make it more energy-efficient.
