The solar radiation at the earth’s surface has a wave length band between 0.3 and 3.0μm, and a peak spectral sensitivity at 0.48μm. Total solar radiation intensity varies from zero at sun rise and sun set to a maximum of about 1,070 W/m2 at noon.
The solar radiation can be used in three processes:
· Heliothermal (absorption and conversion of solar radiation into heat).
· Heliochemical: (shorter wavelength can cause chemical reaction, sustain growth of plants and animal, converts carbon dioxide to oxygen by photosynthesis and cause degradation and fading of fabrics, plastics and paints).
· Helioelectrical: (the energy between 0.33 and 1.30μm can be converted directly into electricity by photovoltaic cells).
