The climate of Tajikistan is very favorable for the use of solar energy. On average there are 280-330 sunny days per year, and total solar radiation intensity varies during the year between 280 and 925 MJ/m2 in the foothills, and between 360 and 1120 MJ/m2 in the highlands. Use of available solar energy in Tajikistan can meet 10-20% of energy demand. Estimated potential of solar energy in Tajikistan is about 25 billion kWh / year. This potential is not used, if not to take into account some of its use for water heating.

There is small wind energy potential, but its use as a complementary main hydropower is justified in some regions. There is small wind energy potential, but its use as a complementary main hydropower justified in some regions. The strongest winds are observed in mountainous areas, where the landscape of the country finds the maximum wind speed and flows, as well as in the Sughd region and the Rasht Valley. Mean wind speed in these regions is about 5-6 m/sec.
