34.8KW solar rooftop plant at diamond grading institute

Times of India, February 2018
The International Institute of Diamond Grading and Research (IIDGR), a part of the world’s leading De Beers Group, has become the first international company in the Diamond City to install a 34.8 kilowatt solar roof at its grading and inscription facility.
In a big move for providing its operations with renewable energy supply, the IIDGR will be generating an average of 56,000 units of electricity each year, thereby reducing the heat load of the building by 90% and significantly decreasing electricity used for air-conditioning.
