It was in 2008 when the announcement of the National Action Plan on Climate Change (NAPCC) identified the development of solar power technologies as a “national mission”. One of the most notable government initiatives in the field was the Jawaharlal Nehru National Solar Mission, launched in two phases in 2010 and 2012, with a third phase to be launched soon. Its targets included 20 GW of solar capacity by 2022, inclusion of around 20,000 villages or hamlets, development of “solar cities”, deployment of 25,000 solar water pumps, solar telecom towers and subsidised solar installations.
The most obvious limitation of solar power is the high price of photovoltaic cells and other related equipment. It requires larger surface areas and installation is profitable mostly when electricity is generated by large, centralised power plants instead of sporadic, decentralised installation on, say, household rooftops, which are difficult to integrate with the grid.
When the solar system is located at the consumer’s premises, the transmission and distribution costs of centralised generators can be avoided. It would entail more judicious use of land-space (as seen in the use of the rooftop of a metro station), against the hoarding of vast amounts of natural land, possibly habitats and environmental assets. The community, including residential, commercial and industrial users, would generate its own electricity and would be empowered by direct control over what it produces,
Only depending on decentralised would be a mistake, while dependence on centralised solar power production in villages has left many houses without power. For rural and urban household production, decentralisation is the way to go. Hence, it is important to have diversification of ways of producing and a right mix of both the production models
As compared to 1 cusec water output through conventional motor, solar pump gives only 0.2-0.3 cusec since its capacity is limited to 2 horse power. Also, due to low capacity, it can only pump water from shallow depths like we are lifting water from a small tank. With ground water table dropping consistently, it can never replace the electricity or diesel-run motors
|Calculate your solar potential|
|The Energy and Resources Institute (TERI) has released the first-ever cloud based Open-source Web-GIS tool for estimating rooftop solar power potential for Indian cities. This tool will help anybody to estimate how much he can save in their energy bills if he has a solar panel on the roof. This tool is currently available only for the city of Chandigarh but TERI plans to expand it to other cities as well.|
