Description
Solar energy and heat from the sun has been collected by humans since ancient times using a plethora of technologies. Solar radiation accounts for most of the available renewable energy on earth. Only a tiny fraction of available solar energy is used.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. 1
