Sri Lanka's Rooftop Solar Doubles as 109,000 Homes Go Green

Over 108,000 homes and businesses across Sri Lanka are now powered by rooftop solar panels, generating enough clean electricity to light up entire cities.

The country added nearly 800 megawatts of rooftop solar capacity in 2025 alone, bringing the total to 1,935 megawatts. That's enough to power roughly 1.5 million homes and represents a stunning 93% jump in solar generation compared to the previous year.

Now Sri Lanka is launching an upgraded system to keep that momentum going. Starting March 5, 2026, all new rooftop solar installations will operate under a program called Net Plus, replacing the old net metering approach.

The new system pays homeowners fixed rates for the electricity they generate. Small systems up to 10 kilowatts earn about 5 cents per kilowatt hour, while larger installations receive slightly lower rates. The government has locked in these payments through February 2027, giving families predictable income from their solar investments.

Here's where it gets even better. Homeowners who add battery storage to their solar systems can earn nearly triple the rate during peak demand hours. Those systems receive 15 cents per kilowatt hour during priority periods for the first 15 years, making it far more attractive to store solar energy for when the grid needs it most.

Every new system will come equipped with smart meters that let utility companies track generation in real time. This modern infrastructure helps balance the grid and ensures homeowners get paid accurately for every watt they contribute.

The switch from net metering to feed-in tariffs might sound technical, but it solves a practical problem. Under the old system, homeowners could only offset their own electricity bills. Now they become mini power plants, earning direct payments for contributing clean energy to the national grid.

The Ripple Effect

This solar surge is transforming Sri Lanka's entire energy landscape. The island nation is building energy independence one rooftop at a time, reducing reliance on imported fossil fuels while creating thousands of jobs in installation and maintenance.

The timing couldn't be better. As climate challenges intensify across South Asia, Sri Lanka is proving that small individual actions add up to massive collective impact. Every home that goes solar helps stabilize electricity costs for everyone while cutting carbon emissions.

The 12-year contract terms give families long-term security, knowing exactly what their solar investment will earn. Meanwhile, the higher rates for battery storage systems encourage homeowners to help solve the intermittency challenge that has long held back renewable energy.

Other developing nations are watching closely as Sri Lanka demonstrates how smart policy can accelerate clean energy adoption without massive government subsidies.

Sri Lanka's rooftop solar revolution shows what happens when a country makes it simple and profitable for everyday people to become part of the climate solution.
