BENGALURU, India — Just a number of years in the past, somebody who wished to put in a rooftop photo voltaic connection in India confronted getting a number of approvals, discovering a dependable firm to put in the panels and spending closely earlier than seeing the primary surge of unpolluted power.

But that is altering. The authorities has streamlined the approvals course of, made it simpler for folks to assert subsidies and pushed mountains of money — together with $9 billion introduced this month — to encourage sooner adoption of expertise that is seen as crucial for India to succeed in its clean-energy objectives.

“We had to get 45 signatures to set up a small rooftop solar connection in 2021,” stated Shreya Mishra, CEO of Mumbai-based Solar Square, one in all India’s largest rooftop photo voltaic firms. “Today it’s almost instantaneous.”

For this sun-soaked nation, progress in rooftop photo voltaic cannot come quickly sufficient. India final 12 months turned the world’s most populous nation, with 1.4 billion folks and a starvation for power that’s rising quick.

Yet India, one of many world’s greatest emitters of planet-warming gases, can be extremely susceptible to local weather change. Its persons are affected by lethal floods, excessive rainfall, excessive warmth, extended droughts and cyclones with rising frequency. A research earlier this 12 months discovered that 9 out of India’s 28 states can be among the many world’s hardest-hit areas as a result of local weather change by midcentury.

India has grown its clear energy quickly lately and has the fourth-most put in renewable energy, trailing solely China, the U.S. and Brazil. It had 180 gigawatts as of December, sufficient to energy about 18 million properties, with almost half from photo voltaic.

Energy consultants say rooftop photo voltaic is important to convey energy to distant areas, the place it may be put in cheaply the place it is wanted and keep away from the price of transmitting the power over lengthy distances.

India’s newest push was introduced by Prime Minister Narendra Modi, who stated the $9 billion would supply “free electricity” for as much as 10 million properties.

Neeraj Kuldeep of the New Delhi-based assume tank, Council on Energy, Environment and Water, has tracked rooftop photo voltaic for almost a decade. A report from CEEW final 12 months discovered that solely 50% of Indians are seemingly conscious of rooftop photo voltaic as an power answer and most of those that have been conscious thought it was too costly. The report launched final November advisable subsidies for shoppers who can profit from small rooftop photo voltaic arrays however cannot afford them.

Kuldeep stated shopper consciousness about rooftop photo voltaic is one key to driving progress. Others are environment friendly governments at each the federal and state degree, and discovering the suitable “fit” for a selected person’s energy wants.

Experts say one other is getting buy-in from state-owned electrical energy firms who generally see rooftop photo voltaic as a menace to their earnings.

Kuldeep stated that is short-sighted. The firms can typically really make more cash if they assist set up rooftop photo voltaic in a low-consumption residence, he stated. That’s as a result of they minimize their transmission and distribution prices to hold energy to a home with a backed invoice that already earns them little revenue.

Installations have additionally risen for the reason that authorities launched a nationwide rooftop photo voltaic portal in 2022 that customers can use to assert and steer authorities subsidies on to their checking account, say consultants and rooftop photo voltaic firms.

Mysun, a rooftop photo voltaic firm primarily based in New Delhi, gives potential consumers a “solar calculator” on its web site the place they will enter their location and present electrical energy prices to see what sort of financial savings they may anticipate. CEO Gagan Vermani stated it is about simplifying the method for potential prospects.

“We need to start thinking of (rooftop solar) with consumer needs in mind rather than thinking of it as building solar infrastructure,” he stated.

Those who’re already connected with panels on their roofs tout the advantages of cheaper electrical energy and better company over their very own energy.

“It is a little expensive but it’s totally worth it,” stated Ruchika Chahana, who lives within the prosperous Greater Kailash neighborhood in New Delhi. Chahana put in rooftop photo voltaic in her residence 9 months in the past at a value of almost $5,000. She stated her summer time electrical energy payments have fallen to about $50 a month, from $200, and her household feels nice about “doing one thing to save lots of the planet.”

In Bengaluru, Satish Mallya saw rooftop solar as essential both to save money and avert carbon emissions. He took the lead in installing 65 kilowatts of solar atop the 120-unit apartment complex he lives in, and the building’s electricity costs have dropped $700 a month.

That 2020 installation was “challenging” because of bureaucratic hurdles, said Mallya, who serves as vice president of a citywide group that represents apartment dwellers and owners. He’s helped many others set up their own rooftop solar connections in the years since, and says the process has gotten easier.

Mishra, of Solar Square, said she’s seeing a big increase in interest in a technology that she calls “a key part of India’s energy future.”

“As an Indian and an entrepreneur, I’m extremely proud of seeing this getting built up,” she said. “I feel constructing power infrastructure is the best nation-building factor we are able to do.”
