Multiple factors have kept households from adopting rooftop installations, but financial benefits might make them more interested this time
After the inauguration of the Ayodhya Ram temple on January 22, Prime Minister Narendra Modi announced the Pradhan Mantri Suryodaya Yojana (PMSY) later in the evening. The scheme aims to provide rooftop solar (RTS) power systems to 1 crore households, which will help poor and middle-income houses lower their electricity bills. On February 1, Minister of Finance Nirmala Sitharaman said in her interim Budget speech that the 1 crore households can get up to 300 units of free solar electricity every month, and save up to Rs 18,000 annually, while selling the surplus to power distribution companies.
For more than a decade, the government has been trying to boost the RTS power sector. The central and state governments have undertaken many initiatives, including policy, regulatory, fiscal, and financial measures, to promote RTS installations, but India missed its target to achieve installed capacity of 40 GW by 2022. The government has now extended this deadline to 2026. (See box.)
India’s total solar power installed capacity has increased almost 30 times since 2014, from 2.6 GW to 70.1 GW, according to the Ministry of New and Renewable Energy (MNRE) website; the RTS installed capacity was around 11.08 GW as of December 2023. Overall, the country has 6.7 lakh households with rooftop solar systems. Gujarat is among the highest adopters with 2.8 GW, followed by Maharashtra at 1.7 GW. Recently, Gujarat’s Energy Minister Kanu Desai said that 82 percent of the country's rooftop solar capacity lie within the state's borders.
Yet, RTS installations have been comparatively low in the residential sector due to various reasons. Installation is expensive; there is lack of awareness, and issues regarding implementation and administrative hassles around metering approvals persist; lack of timely disbursement of central and state subsidies is a concern, and some consumers are getting subsidised electricity from power distribution companies. The Karnataka government has seen a significant dip in the number of residential RTS installations in cities over the last few months, as many households started receiving either a zero bill or a subsidised bill under the state’s Gruha Jyothi Scheme.
Under the recently announced PMSY, homes need a minimum area of 10 sq m to install a 1-kW solar panel. A 40 percent subsidy will be given for installing panels ranging from 1 to 3 kW, and a 20 percent subsidy for panels ranging from 4 to 10 kW. One can apply for it through the national RTS website. State governments are actively promoting the scheme. For instance, Chandigarh has reportedly received 1,200 applications from residents who are keen on installing RTS.
