In stall Rooftop Solar PV to Save Earth and Money

In stall Rooftop Solar PV to Save Earth and Money

Earth temperature is rising at a faster rate which is a major concern to our environment and earth. We are mainly dependent on thermal power stations for our electricity. These thermal power stations produce very high pollution. The top pollution producing countries are china, India and USA.  Presently, our country is at second place in producing the pollution in the world, a few years ago our country was at third place in producing the pollution. For reducing the pollution we will have to reduce the dependency for the electricity on thermal power stations. We will have to increase dependency on renewable energy resources like solar, hydro, wind etc. The highest solar resources are available in Rajasthan and this solar resources can be utilised for generation of electricity. Secondly electricity produced by solar rooftop PV is cheaper than the electricity of Discom's. Therefore, we can install Solar PV modules at our roof. These solar PV modules have a minimum life of 25 years. Therefore, we can generate the electricity for 25 years from Solar PV plants installed at our roof. Our discussion is limited to Commercial, Industrial, Residential and Institutional sectors.

Commercial Sector

Government does not provide any subsidy in commercial sector since the tariff is highest in commercial sector and the cost of solar PV Plants has come down. However, Government provide accelerated depreciation i.e. tax benefit. The commercial sector have a highest tariff and commercial peoples are incurring heavy losses on account of purchasing electricity from discoms. Payback period of solar PV plant is less than 4.5 years without considering the benefit of accelerated depreciation, it means electricity is free just before 4.5 years and up to 25 years.  It is not understood why commercials peoples are paying such a huge tariff to discoms and heavily losing money.  It shows that commercial peoples are not aware about the benefit of installation of solar PV plant at roof.  If commercial peoples have sufficient space and south direction is shadow free, then they should utilize the space for generation of electricity.

Industrial Sector

Government does not provide any subsidy in industrial sector also since the tariff is slightly lower than commercial sector and the cost of solar Pv Plants has come down. However, Government provide accelerated depreciation i.e. tax benefit. The Industrial sector have second highest tariff and industrialist are incurring very heavy losses on account of purchasing electricity from discoms. Payback period is less than 4.5 years without considering the benefit of accelerated depreciation, it means electricity is free after 4.5 years and up to 25 years. The electricity consumption in industries is very high, therefore, it is not understood why industrialist are paying such a huge electricity bills to discoms and very heavily losing money.  It shows that industrialist are not aware about the benefit of installation of solar PV plant at roof.  If industrialist have sufficient shadow free space in south direction, then they should utilize the space for generation electricity.

Residential and Institutional sector

Government provide subsidy in residential institutional sectors since lowest tariff. Therefore, payback period is high. It is economical when consumption is huge and you have sufficient shadow free space in south direction. Government provides subsidy time to time for encouragement of installation of solar PV Plant for residential and institutional sector.

Conclusion

Industries shall be highly benefited by installation of rooftop solar PV because their consumption is very high, installation of Large Capacity solar plant  have less cost and they have enough space for installation of rooftop solar plant. Industrialist should get assessed of the losses from installer/consultant. In fact they are paying high bills to Discom and losing money. Commercial peoples should install rooftop solar PV at all cost if they have sufficient shadow free area in south direction. Residential and Institutional have the lowest tariff and therefore should install the solar PV plant with the Government Subsidy.
