You have probably wondered this while staring at your rooftop panels during a heavy monsoon downpour: do they still make electricity when the sun hides behind clouds? Or at night, when there is no sun at all? Let's clear this up, and also look at where India stands in the solar energy race.
Why Solar Panels Go Quiet at Night
Solar panels turn sunlight into electricity. No sunlight, no electricity. That's the simple rule. At night, panels sit idle because there is nothing for them to work with. During the monsoon, thick clouds and constant rain block a lot of sunlight too, so panels produce less power than they do on a clear day.
So How Do Homes Get Power at Night or in Rain?
This is where battery storage comes in. During the day, panels often make more electricity than a home needs. That extra power gets stored in lithium-ion batteries instead of going to waste. When night falls or rain rolls in, the stored electricity kicks in and keeps the lights on.
Another option is a hybrid solar system. This setup combines solar panels with other power sources like wind energy, hydropower, or the regular electricity grid. If the sun is not cooperating, one of these backups fills the gap. Hybrid systems cost more to set up, but they offer steady power no matter the weather.
How Much Does Monsoon Season Cut Power Output?
Experts say solar output can drop by 20 to 50 percent during the monsoon, compared to normal sunny days. The exact drop depends on your location, the weather that week, and the quality of your panels. So if your solar bill savings look smaller in July and August, that's just monsoon doing its thing.
Does Rain Damage Solar Panels?
Here's some good news: regular rain does not harm solar panels. In fact, rain washes away dust and grime sitting on the panel surface, which can actually help performance once the sun comes back out. The real threats are strong storms, hailstorms, or shoddy installation work. Manufacturers now build panels designed to handle moisture and rough weather better, and regular cleaning keeps them running well for years.
India's Rise as a Solar Powerhouse
According to the Press Information Bureau, India has overtaken Japan to become the third largest country in the world for solar power generation and total renewable energy capacity. India's installed solar capacity has crossed 150 gigawatts, with only China and the United States ahead in the rankings.
PM Surya Ghar Yojana: Subsidy for Rooftop Solar
To get more households on board, the central government launched the PM Surya Ghar Muft Bijli Yojana on February 15, 2024. The scheme gives eligible families a subsidy for installing rooftop solar panels. The government's target is to bring one crore homes under this scheme, which should lower electricity bills and push clean energy use across the country.
PM Modi's Bigger Targets for Clean Energy
During a visit to Australia, Prime Minister Narendra Modi spoke about India building a strong manufacturing base for hydro projects, green hydrogen, solar modules, and wind turbines. He laid out three clear targets: 500 gigawatts of renewable energy capacity by 2030, 100 gigawatts of nuclear energy capacity by 2047, and net-zero emissions by 2070. The government is leaning hard on solar and other clean energy sources to hit these numbers.
World Bank Backs India's Solar Rooftop Program
The World Bank has announced major financial support for India's National Solar Rooftop Program. According to Paul Procee, the World Bank's acting country director, the organisation has spent the last decade helping build up India's solar rooftop sector. In that time, rooftop solar capacity grew from just 500 megawatts to over 27 gigawatts, backed by more than 2 billion dollars in funding.
Procee noted that the new financial support will encourage more households to switch to solar and create jobs across the supply chain and installation sectors.
Where the Money Is Coming From
Under this program, the International Bank for Reconstruction and Development (IBRD) will provide an 820 million dollar loan. The Clean Technology Fund will add a 60 million dollar concessional loan, and IBRD's Livable Planet Fund will contribute a 10 million dollar grant. On top of this, the World Bank plans to mobilise 4.2 billion dollars in private financing, which should speed up rooftop solar installations nationwide.
Moez Cherif, the program's task team leader, explained that this initiative will remove financial barriers and strengthen the capacity of power distribution companies, banks, and solar vendors. Homeowners will be able to get collateral-free financial support, making it easier to install solar systems and cut their monthly electricity bills.
17 Lakh Jobs on the Horizon
Beyond bringing clean energy to more homes, the National Solar Rooftop Program aims to create around 17 lakh jobs across renewable energy manufacturing, installation, and service work. India has also set a target of getting 60 percent of its electricity from non-fossil fuel sources by 2035.
So the next time it rains and your solar meter slows down, remember it is not broken. It is just taking a short break, backed by batteries, hybrid systems, and a government plan that is thinking decades ahead.
