India added 678 MW of rooftop solar capacity in 2016-17, growing at 81 per cent over the last year, reaching total installed capacity of 1,396 MW as of March 2017. The southern state of Tamil Nadu continues to lead in rooftop solar projects in the country. With an installed capacity of 163 MW as of March this year, the state outperformed all its peers in rooftop solar installations according to a report by Bridge to India, a global renewable energy consulting firm.
Industries are major drivers for rooftop solar installations in the country, contributing 590 MW. In Tamil Nadu too, the industrial segment contributed about 124 MW. State-owned establishments are expected to show robust growth in the coming years because of strong support from the government combined with 25-30 percent capital subsidies.
Bridge to India expects India’s rooftop solar capacity to cross the 2 GW mark during this fiscal, partly driven by several ongoing and recently completed rooftop solar tenders. The state-owned segment is expected to grow at 205 percent during this fiscal year, reports BusinessLine. Total rooftop solar capacity is expected to reach of 13.2 GW by 2021.
