Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been underway since very beginning for the development of an affordable, in-exhaustive and clean solar energy technology for longer term benefits.
The PV technology convert visible spectrum to electricity and thermal collectors use both infrared and visible spectrum for energy generation. So the energy generation from solar radiation can be in the form of electrical energy or thermal Energy. The various conversion paths of solar energy is described in the Fig.2
As majority of our energy requirements are in the form of electricity, PV works on the principle of photovoltaic effect. The generation of thermal energy from solar can be realized using various solar reflecting collectors. Most of the technology works on the principle of reflection, radiation and convention or based on the thermosiphon effect.
The major factors that limit the use of solar energy for various applications is that, it is cyclic time-dependent energy source. Therefore, solar system requires energy storage to provide energy in the absence of insolation . Comprehensive research and advancement in energy storage technologies offers benefits for solar in energy application.
