Energy school – RE – Solar

Solar power is energy obtained from the sunlight that reaches the Earth. Solar power is harnessed in two main ways: by using photovoltaics to produce electricity, solar thermal systems to heat water or power solar cooling systems.

Even within regions such as northern Europe there is sufficient sunlight to make solar power a good source of energy, and Germany is a leading producer of electricity from solar power. Northern Europe receives between 4.5 and 5 kWh/m2/day in the summer, and southern Europe can receive up to 6 to 7.5 kWh/m2/day. In winter these fall to around 0.5 kWh/m2/day in northern parts and 1.5 to 2 kWh/m2/day in southern parts. 5 kWh of energy is enough to heat up a very hot bath.
