Top States for Rooftop Solar Installations [Infographics]
The top 10 states accounted for nearly 79% of the total rooftop solar installations
Cumulative rooftop solar installations in India reached 4.6 GW as of Q1 2020. In the first quarter of 2020, India installed 194 MW of rooftop solar projects, a decline of 36% as compared to 304 MW in the fourth quarter of 2019. In a year over year comparison, the installations decreased by 26%, compared to 263 MW installed in Q1 2019, according to Mercom India Research’s Q1 2020 India Solar Market Update.
The top 5 states for the rooftop solar account for over 50% of the installations in the country.
Here’s a quick look at the top states in the country for total rooftop solar installations:
32% of Gujarat’s installed power capacity is from renewable sources as of March 2020. Solar specifically accounts for 9%. In the budget announcement for FY 2020-21, the state included a ₹9.12 billion (~$127.19 million) subsidy provision for rooftop solar projects. Gujarat is considered one of the best states for solar largely due to good credit ratings of power distribution companies and their ability to pay on time.
Rajasthan has the best solar irradiation to install solar. Solar contributes to 20% of the state’s total power capacity installed. Rajasthan’s Solar Energy Policy, 2019, aims to install 30 GW of solar power by the financial year 2024-25. Of this, solar rooftop systems are expected to account for 1 GW.
Karnataka is the top state for large-scale solar in the country. The state gets 63% of its installed power capacity from renewables, and 25% of this comes from solar. But the future of rooftop solar in the state looks bleak with unconducive policies proposed.
About 4% of the total installed power capacity in Maharashtra comes from solar. The state is heavily dependent on thermal power (63%).
The most disappointing developments in the rooftop segment in the past few months have been in Karnataka and Maharashtra as both states have introduced business models and charges to curb development in the rooftop segment.
As the country’s top wind power-rich state, half of Tamil Nadu’s installed power capacity is from renewable sources. The share of solar is 12%. In early 2019, the state announced it’s Solar Energy Policy 2019, targeting 9 GW of solar installations by 2023 between utility-scale and distributed generation projects. Of this, the state has targeted 40% (3.6 GW) of installations to come from the consumer category (residential rooftop and small-scale solar installations).
