Savings: After an initial investment, you will have access to free energy nearly all year. Solar electricity systems have a long life and they require very little servicing. By concluding an agreement with the electricity supplier, a small-scale producer of solar energy will be able to receive compensation for the electricity transferred to the grid.
Remember this: Some towns require a planning permit to install a solar electricity system. Apartment dwellers have to obtain permission for installation from the housing company.
Reducing your carbon footprint: Installing 18 m2 of solar panels for each person in your home reduces your carbon footprint by 5% per year. If a million Finns did this, it would save the equivalent of 49,000 carbon footprints and the proportion of renewable electricity in the main grid would increase.
