Solar Radiation Measuring Network, Atlas Out in the Open

CHENNAI: What’s the use of building solar power parks if your place is in a site that doesn’t get enough solar radiation? It is to rectify this hole in available data that Chennai’s own National Institute of Wind Energy, an Institute under the Ministry of New and Renewable Energy, has launched India’s first and the world’s largest solar radiation measuring network and atlas.

Built over a period of three years and a cost of nearly `40 crore, the solar radiation measuring network will be the basis on which the Indian Solar Radiation Atlas will function on. According to officials at NIWE – Solar Radiation Resource Assessment wing(SRRA) 121 ground stations would measure the three parameters of Solar radiation ?- Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DHI) to give a highly accurate measure of solar radiation in a particular region.
