Tracking Photovoltaics Systems at Mountain Heights

Abstract

The expansion of the use of solar energy in most cases depends on the energy capabilities of each specific country. In Tajikistan, where 93% of the territory is mountains, it is necessary to build solar power plants high in the mountains. At mountain heights, the performance of panels increases in winter, in addition, the snow cover that reflects the sun's rays also contributes to an increase in the efficiency of solar panels. Experts note that solar panels receive less radiation in valleys, as clouds and fogs often prevent the passage of sunlight. At the heights of the mountains, there is no air pollution and, as a result, a longer operating time of the solar power plant. In the conditions of Tajikistan, one more drawback of solar stations in the valleys should be added - this is the rapid pollution of the panels due to dust storms in the summer-autumn period. The Chinese company Sun Tech Power Holdings will build a 10 MW power plant in Tibet at an altitude of 4000 meters above sea level.
