Solar panels placed on top of roofs of commercial, institutional or residential buildings are known as Solar Rooftop Systems. They capture the light energy emitted by the sun and convert it into electrical energy. This setup is also known as rooftop photo-voltaic system. It produces a clean, Eco friendly form of energy, meaning that it’s which does not produce any type of pollution or harmful gases. Solar market all over the globe is on a verge to make our mother earth a healthy and secure place to live. A rooftop panel only requires space and abundance amount of sunlight for efficient working, and on some days when the sun is on low spirits, batteries stored in the panels will work as a savior.
The manufacture of solar panels and ancillary components is labor intensive, requires moderately skilled labor. Even setting up solar rooftop systems requires labor power, both directly and indirectly. Post installation, technicians are involved in ensuring timely service and maintenance of these solar rooftops, though this number is fairly low as solar electricity systems are mostly hassle free. According to a report submitted by Bridge to India, job creation in the installation of solar rooftops will be the highest. Manufacturing, designing, business development, administration,design and drawing,project development,accounts are many other job opportunities that spring up with the solar industry.
Various Appliances Powered by Solar Rooftops
Household appliances – Television, thermostat, dryer, fan, radio, refrigerators
Smaller daily use items – Flashlights, wearable like smartwatches and fitness bands, power banks, music speakers
Infrastructural – Street lights, Fans in warehouses etc
Solar rooftops need only the light of the sun to generate electricity, making it a cleaner source of energy than most other usual forms. Its renewable nature promises sustainability. No health hazards are involved and no pollutants are emitted by solar rooftops. No extra land is required to set up rooftops. With widespread usage, solar rooftops can help in minimizing global warming.
Economic Impact of Solar Rooftops
Solar rooftops are very cost effective. They are one-time investments which continue to serve both nature and the society for a much longer time. In the long run, they turn out to be less expensive as compared to diesel generators or even grid electricity. People who switch to solar energy experience a huge cut in electricity bills, hence saving a lot of money.
Solar Rooftops in Residential Areas
Solar rooftops are now being increasingly used for residential areas – both large complexes as well as medium to large-scale private housing e.g. About 280 households in Gandhinagar were fitted with solar panels last year. Resale value of a house will also increase if it comes with an installed solar rooftop system. The money spent on terrifying electricity bills will be cut short and the money saved can help a family invest in a better lifestyle.
Social Implications of Solar Rooftops
Setting up solar rooftops is also philanthropic in nature. It not only serves the environment but serves society as a whole. There are schools and colleges in various small districts of the nation where the supply of electricity is improper, this poses a threat to education of the pupils, also because of lack of power the students in villages cannot take up digital education, especially during the night they are not able to study because of darkness.All these problems could be overcome by adopting solar techniques. The hospitals will not face any obstacle in treating their patients because of lack of power. The use of cleaner energy will also increase the life expectancy rate among people.
India has become a leading nation in solar energy. In its Budget 2015 India announced a target of adding 175 GW of renewable energy, including 100 GW of solar power, by 2022. A subsidy of 30% for setting up solar rooftops has been given to general category states and 70 % to special category states.
Solar rooftops have an expected life of 25 years which make them worth the investment.
