The research results that prove a great potential of renewable and alternative energy sources in the Republic of Tajikistan, including solar energy, equal to 25 billion kWh per year are presented in the paper. A limited use of "green energy" leads to periodic blackouts of electricity consumers in the autumn-winter period. To eliminate the emerging electricity shortage, a more complete picture of the potential of solar energy is required. The paper gives an assessment of the energy potential of solar radiation in the regions of the Pamirs and the south of Tajikistan. A mathematical model is presented to determine the maximum value of the azimuthal angle for the Pamir region. Expressions are proposed for evaluating the functioning of two systems and the increment of solar radiation and energy potential taking into account the duration of daylight. Measurements were taken and monthly, seasonal and annual levels of solar radiation were calculated based on the use of two technical systems. It is shown that the energy efficiency of the biaxial tracking system (BTS) significantly exceeds the efficiency of the fixed system (FS) especially in the autumn, spring and summer seasons of the year. A comparative analysis of the production of solar energy and the efficiency of the two systems using a solar tracker for the biaxial tracking system and the fixed system is made. It is shown that the annual productivity of the biaxial system of the solar tracker compared with the fixed system is on average 44% higher. In the autumn period, the mobile system can generate 80% more energy relative to the stationary arrangement of solar panels. The assessment of the solar potential of the regions of Tajikistan proves the feasibility of using this potential as a suitable resource for the development of energy, complementing hydro generation.
