It is the cleanest and abundantly found and inexhaustible source of energy. It can be derived from modern technologies like solar thermal energy, molten salt power plants, solar architecture, solar heating device, and many more. It is used for generating Energy Plans for personal, commercial, and industrial purposes.
Where does solar energy originate?
We get solar energy from the sun’s radiant light and heat. Sun is the source of all energy. It releases energy at the rate of 3.8X1023 kW/sec. Earth which about 150 million km away from the sun only receives a tiny fraction of approx. 1.8×1014 kW/sec of energy and rest is reflected in space and absorbed by the atmosphere.
Till now we can only able to convert only 0.1% of energy. But even if we able to transfigure 10% of it, will be four times the World’s total generating capacity of about 3000GW. It is quite interesting to know that the total solar radiation falling on the earth is more than 7500 times but the world consumes only 450 EJ.
Advantage of Solar energy
- The solar panel can produce free of charge electricity, once installed on the rooftop
- While it is estimated that the world’s oil will run out in 40 years but this energy will last forever.
- This energy causes no pollution at all. They are environments friendly.
- Once installed it is estimated that a normal family can generate half of its energy from solar panels.
The disadvantage of solar energy
- It is the problem with all renewable energy is that its regularity. As in the case of Solar energy, the sun is the major source that is not there at night and on cloudy days or during the rainy season
- Due to its irregularity, we cannot rely totally on solar energy regularly.
- Solar panels require additional equipment for converting Direct power into Alternative current
- It has a high inceptive capital cost. Although the installation of the solar panel brings massive benefits in the long run its initial cost is very high. Though some nations introduce rebates and tax credits to encourage people to install solar panels, unless you are putting huge money aside, it can be an unbearable cost.
Solar Energy Rate Of Consumption In India
In the coming years, India will be the largest producer of solar energy in the World. The Indian government is planning to have 20 GW of solar capacity in the country by 2022. Gujarat has the largest solar plant in India and third in the world built by Gujarat Power Corporation. It has a peak capacity of more than 200MW. Similar projects were adopted by other states in India like Tamil Nadu has a regional target of 3GW of solar capacity in 2015. Maharashtra has 160 MW of solar capacity. According to KPMG, the Indian Government has various solar projects in the coming year. In 2011 the average cost of the solar system with 5 to 10kW of capacity in India range between 2.5 – 3.0 USD per watt and 2.4 USD/W is the average price for large-scale solar plants. The price of the PV dropped to 2.2 USD/W as reported by IRENA in 2012.
