The Indian solar market is predicted to more than double to 1.8 GW in 2015 The cumulative solar capacity in India as of May 31, 2015 stood at 4.4 GW. While in Rajasthan and Madhya Pradesh maximum capacity was added under NSM projects, in Punjab the state solar policy was the key driver.
New allocations which will start converting in the next 1-2 years include Punjab phase II (250 MW allocations), Karnataka Phase II (500 MW allocations), Andhra Pradesh (500 MW allocations), Telangana (500 MW allocations), Uttar Pradesh (115 MW), and Bihar (130 MW). Hence, in total about 2 GW of new capacity from state allocations is expected in the next 1-2 years.In the rooftop segment, as of May 31, 2015 only 350 MW was installed.
Maharashtra and Tamil Nadu are the leading states. Maharashtra has India's highest industrial and commercial tariffs. Tamil Nadu has been facing power supply shortages and has a high consumer awareness with respect to solar power generation.
