What is the Future Outlook for Solar Energy in Sri Lanka?Government targets aim for 70-80% from renewables by 2030, up from just 2% in 2018. This will require $2-3 billion in solar investments by 2025.Rooftop solar technical potential is estimated at 6 GW, with policy support needed to unlock adoption. . Utility-scale solar parks of 100-200 MW are planned in Poonerin, Siyambalanduwa, and Hambantota. . 更多项目 [pdf]
Sri Lanka receives significant amount of solar radiation across all geographical regions. The Global Horizontal Irradiance (GHI) varies between 1,247 kWh/m 2 to 2,106 kWh/m 2. It is interesting to note that the intensity of solar irradiation in lowland areas is high compared to mountainous regions.
Hayleys Solar partners with leading tier-1 solar panel manufacturers around the world to provide the best solar panels in Sri Lanka. All our solar system projects are fitted with durable and conversion-efficient solar panels to ensure that our customers receive long-lasting solar systems.
The Solar Resource Atlas of Sri Lanka is an important addition to the existing knowledge on solar resources of Sri Lanka. The first solar atlas of Sri Lanka was prepared by the National Renewable Energy Laboratory (NREL) of USA, in 2005, as the Wind and Solar Resource Atlas of Sri Lanka and Maldives.
The first solar atlas of Sri Lanka was prepared by the National Renewable Energy Laboratory (NREL) of USA, in 2005, as the Wind and Solar Resource Atlas of Sri Lanka and Maldives. Such attempts in exploring solar resources of the country provided valuable information leading to gross estimates of solar potential.
Specifically for Sri Lanka, country factsheet has been elaborated, including the information on solar resource and PV power potential country statistics, seasonal electricity generation variations, LCOE estimates and cross-correlation with the relevant socio-economic indicators.

Sephu plant will serve as an addition to the 180 kW grid-connected ground-mounted solar photovoltaic power station in Rubesa (near ), which became operational in October 2021. The Sephu plant is currently under construction over an area of 65 acres in Yongtru village, situated in the . Upon its completion, the overall installed capacity of the facility will reach 22.38 megawatts and is expected to be complete by March 2025. It was initially planned. [pdf]
The Sephu project will be Bhutan’s largest solar facility. Credit: Bhutan ministry of energy and natural resources The Bhutanese government has started construction on the country’s first utility-scale solar farm, the Sephu solar project, which boasts a capacity of 17.38MW.
“We did the studies on renewable energy management master planning in 2016 and the reports say Bhutan has a capacity for 12 Giga watts of solar energy and 760 MW of wind so we have a lot to tap as there is a lot of opportunity for solar energy solar power to grow in Bhutan. There is a lot of potential and I think this is the right step.”
The Bhutanese government has started construction on the country’s first utility-scale solar farm, the 17.38MW Sephu solar project.
The Prime Minister Dasho Dr Lotay Tshering was the Chief Guest. Bhutan Solar Initiative Project (BSIP) set up under Royal Command has implemented two Solar PV Projects in Thimphu. 250kW Rooftop Centenary Farmers Market (CMF) and 500kW Ground mounted at Dechencholing.
In 2021, the first planned mega solar power plant, a 30 megawatt, in Shingkhar Bumthang was dropped because the community refused to give clearance for various reasons. The plant was expected to generate 46.19 million units of energy annually with an annual revenue generation of Nu 233.725 million.
Minister of Energy and Natural Resources, Loknath Sharma said, “Sephu solar plant is the first medium solar farm in the country.” The minister said that Sephu solar plant marked the beginning of achieving a 500-megawatt energy target through solar power in the next three years. He said that the plant project is undertaken by the ministry.
