Solar energy in Finland

Solar energy in Finland is used primarily for water heating and by the use of photovoltaics to generate electricity.

Due to the low sun angle, it is more common to place solar panels on the south side of buildings instead of on the roof.

Although the city of Oulu, located near the Arctic Circle, has only two hours of weak sunlight in December, the photovoltaic cells work almost around the clock in the summer.
