Obviously, the main reason to install solar panels is to drastically reduce your energy bill or even to switch completely to renewable energy. A standard family of 4 people consumes +- 3500-5500 kWh per year. As a result, an electricity bill quickly runs up.
By installing solar panels, you are not only making an investment to reduce your electricity bill. You are also contributing to a greener world where renewable energy is central and increasingly taking precedence over fossil fuels
