Solar Energy needs to be harnessed. The term Solar Energy in general refers to the 2 types of Energy produced by The Sun - Heat Energy and Light Energy. Both forms of Solar Energy have been in use in India for quite sometime although Solar Thermal has been more popular as it is a relatively older technology and has found widespread application at household levels as well.
Solar Photo Voltaic on the other hand is relatively new in Solar Energy space in India. Although Solar PV has been in use at a smaller scale (Calculators, Watches, Lanterns)., the use of Solar Photo Voltaic as a Power Source in India is a relatively new and emerging concept.
Solar Energy has been used by mankind since long. Earlier however the use was restricted to utilization of Solar Energy for basic drying or heating purposes. It was soon realized that Solar Energy can be put to better use by utilization of Sophisticated system for Water heating used at domestic level, or Industrial level, drying etc.
With passing time it was realized that Solar Photo Voltaic can be used as a Power source not just for satellites but as also the cleanest and greenest power source on Earth. Solar Energy thus started being used not just for conventional purposes such as heating but also power generation.
Solar Energy in India
Solar Energy is one of the cleanest and greenest technology. Although Solar Energy in India is led by Solar Thermal., it is expected that Solar PV in India will prove to be the single largest source of power in the times to come.
As in case of any new technology the support extended by Government of India by way of providing attractive incentives under Jawaharlal Nehru National Solar Mission (JNNSM) is generating significant interest in Solar Energy especially in Solar Photo Voltaic.
India has Geographical advantage with excellent Solar radiation across the Country. It is thus no rocket Science that Solar Energy will prove to be the single most promising Energy Source of the future. In fact Rajasthan has been recently termed as among the best in the world for Solar Energy. Even other parts of India including Gujarat, Maharashtra, Madhya Prades, Chhattisgarh, Karnataka, Eastern Belt, Southern Belt (especially around Chennai), Northern Belt received very good to excellent Solar Energy.
