Mauno Mäentaus got himself a 20,000 euro solar power plant and started selling the surplus to the electricity company.
Of the fields and in the embrace of the forest landscape in Kosk I live Mauno Mäentaustan, 71, the end wall of the garage is full of solar panels. They are also on the other side of the gable roof of the building.
Mäentaus uses part of the electricity produced by the solar panels itself. He sells the rest to the electricity company. This is possible because the solar electricity system is connected to the electricity grid and Mäentaus has agreed to sell surplus electricity with its electricity company.
