The term solar radiation or solar power refers to the complete energy spectrum radiated from the sun. Direct sunlight includes infrared, visible, and ultraviolet light energies. These energies can be recorded, photographed (as in eclipses and auroras or for coronal and sunspot study), and utilized in devices such as solar cells or passive solar collectors. Parabolic Dish-Stirling Engine Technology increases efficiency in utilizing solar power. Solar energy is free and clean—hence, green.
