Solar Energy has been used by mankind for a long time. However technology has evolved from using Solar Energy for natural drying to cookers to Solar Water Heaters and now Solar Photo Voltaic for Power Generation.
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 utilization by Sophisticated system for Water heating used at domestic level, or Industrial level, drying etc. The use of Solar Energy for electrical power generation dates back to advent of Space Technology when Solar Photo Voltaic cells were used to power Satellites orbiting around the Earth and with a requirement of a consistent and reliable power supply.
Photo Voltaic Solar has been in use on a smaller scale for eg. in Watches, Calculators and Lanterns. Photo Voltaic Solar Power Projects is a relatively new and emerging concept in the Indian context. However the same is widely used and well-accepted on a large-scale Globally.
Ironically PV Solar has seen tremendous growth in several Nations which do not receive very good radiation or Sunlight. It is thus no surprise that India - which receives one of the best Solar radiations - and is also suffering from acute power shortage will utilize Solar Energy in a big way in the times to come. Major part of Utilization would be focused on Power Generation due to huge power deficit. Further more Solar Photo Voltaic also has various distinct advantages in general. In fact Solar Photo Voltaic also over other Renewable Technologies.
