Solar Energy: Technologies and Systems

The radiant heat and light from the sun is known as solar energy. It is harnessed using a wide variety of technologies such as photovoltaics, solar architecture, artificial photosynthesis and solar heating. These technologies are broadly classified into passive solar and active solar. This classification is done on the basis of how they capture and distribute solar energy. Passive solar technologies do not use any external mechanical or electrical devices. On the other hand, active solar sy...
