As of 2023, Laos has made limited progress in grid-connected solar systems, with only eight small solar farms operational, with only one existing rooftop solar system installation to date: a 236kW plant at Wattay International Airport. In Laos, the yearly sunshine varies by location. In Vientiane, the average is approximately 2,420 hours of sunlight annually, equating to about 6 hours and 37 minutes per day. These installations are part of an off-grid electrification scheme supported by the Laos government and the World Bank, providing power to rural areas where grid access is limited. The amount of energy you can expect to generate from each kilowatt of installed solar panels varies slightly by season: 5. 73 kilowatt-hours. Specifically for Laos, 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.
