The first were installed in 2009, and are not associated with storage. The installed capacity is 13 MW, in particular via the Longoni power plant, inaugurated in 2010. Solar energy is the only renewable energy with significant development potential on the island; the wind potential (22 MW according to a study) would not lead to a significant production because the wind blows only 6 months per year.
[pdf] Renewable energy in Nepal comes from hydropower, solar energy, biomass, biogas, and wind energy. Nepal has favorable solar resources, receiving average solar radiation of 3.6 to 6.2 kW/m /day. Sunshine duration is around three hundred days per year or 6.8 hours per day, equivalent to approximately 2100 hours annually. This indicates good potential for solar power generation acr.
