Finland differs from most industrialized countries in that many of its energy needs stem from the Nordic conditions. Finland is located between 60 and 70 degrees northern latitude and a quarter of its area lies north of the Arctic Circle. In fact, one third of all people living north of the 60th parallel are Finns. The annual mean temperature in the south of the country is around 5 °C and 0 °C in the north. The population-weighted average number of for Finland is 5. .
Solar energy in Finland is used primarily for water heating and by the use of to generate electricity. As a northern country, summer days are long and winter days are short. Above the , the sun does not rise some days in winter, and does not set some days in the summer. Due to the low sun angle, it is more common to place solar panels on the south side of buildi.

[pdf] Concentrating Solar Power (CSP) systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. The concentrated heat is then used as a heat source for a conventional power plant. A wide range of concentrating technologies exists; the most developed are the parabolic trough, the solar tower collectors, the concentrating linear Fresnel reflector, and the Stirling dish. Various techniques are used to track the Sun and focus light. In a.
