The brief highlights the Renewable Energy projects under the Indo-German Energy Programme (IGEN) that supports the Ministry of New and Renewable Energy (MNRE) of the Government of India to establish a network of solar radiation data monitoring units in India for a countrywide Solar Radiation Resource Assessment (SRRA) mission. Under the project GIZ supports Centre for Wind Energy Technology (C-WET) to develop a precise and value added database on solar radiation and other weather parameters which is crucial for making a national solar radiation atlas in the future. Develop a system for the collection of weather data along with complete solar radiation data for the preparation of solar maps for India, and develop and test a benchmarking system for performance monitoring of solar electricity plants. There are 51 locations in India where solar radiation measuring stations have been successfully set up by MNRE/CWET with active support of GIZ.
