The history of solar energy started in 1921, when the photovoltaic effect was discovered. In the 1950s PV power satellites were sent into orbit. The oil embargo in the 1980s led to a reorganization of energy politics and heralded the Green Revolution.
First, we have to choose between an active and a passive solar water heater system. Then, we have to select the type of collector for our solar water heater. It is also important to consider the right size of the pipe line.
A solar pool heater can reduce heating costs significantly. In many climates, solar pool heating is the most cost-effective use of solar energy. As swimming pools are used most when it´s warm and the sun is shining, solar heating is an ideal application.
A solar panel collects light energy from the sun and turns it into electricity. Roof mounting is a common form of positioning solar panels. By mounting on the roof, you put the photovoltaic cells in a location that gives them a full dose of sunshine.
