    How much solar radiation does Sri Lanka receive?

    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.

    Who created the first solar atlas 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.
