The average solar panel has an input rate of roughly 1000 Watts per square meter, while the majority of solar panels on the market have an input rate of around 15-20 percent. As a result,
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
Below is the average daily output per kW of Solar PV installed for each season, along with the ideal solar panel tilt angles calculated for various locations in Sri Lanka. Click on any location for more detailed information. Explore the solar
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at
Solar Panels are installed on the roof of your house that generates DC electricity, which is then converted to AC electricity via an Inverter, and then fed on to the National Grid which is
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.

If the generated units of electricity using the solar panels fixed on houses/premises are greater than the amount consumed, the excess will be paid at the rate of Rs.22.00 per unit during the
Sri Lanka is blessed with plentiful sunlight year-round. The Global Horizontal Irradiance (GHI), which is the universal measure for solar intensity, varies between 1,247 kWh/m2 to 2,106 kWh/m2 [1]. According to a recent study jointly conducted by the UNDP and ADB, Sri Lanka has the potential to deploy 16 GW of solar power [2].
80 Panels: Panel Size: 27 square foot (ft²) Roof Surface Area Required: 2190 square foot (ft²) Total Panel Weight Why switch to solar power. Sri Lanka is one of the most expensive
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal
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
According to the Asian Development Bank (ADB), Sri Lanka receives 4-6 kWh per square meter of solar insolation daily with around 5-7 hours of sunshine. This tropical climate allows for solar photovoltaic systems to operate effectively year-round.
Seasonal solar PV output for Latitude: 6.7195, Longitude: 80.0644 (Horana South, Sri Lanka), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
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.
Solar power is an emerging energy source in Sri Lanka. According to the Ceylon Electricity Board (CEB), the installed solar capacity was around 164 MW as of 2018, contributing 0.4% of total electricity generation. However, solar adoption is rapidly increasing driven by favorable policies.
Solar power is poised for strong growth in Sri Lanka driven by policy support, improving economics and environmental benefits. 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.
Solar resource (GHI, DNI, DIF, GTI, OPTA), PV power potential (PVOUT) and other parameters are provided in the form of raster (gridded) data in two formats: GeoTIFF and AAIGRID (Esri ASCII Grid). Provided data layers are in a geographic spatial reference ( EPSG:4326 ).
