EXPERIMENTAL STUDY OF THE EFFICIENCY OF BIFACIAL SOLAR MODULES IN THE CLIMATIC CONDITIONS OF KAZAKHSTAN

Abstract

Bifacial solar modules consist of solar cells that absorb solar radiation from both the front and the back. They convert solar energy into electrical energy from two surfaces, that is, from the front and back. The solar radiation conversion efficiency of such solar modules on the front side is several percent higher than on the rear, and reaches 18-19%. And the efficiency of the solar module at the back is 14-15%. Double-sided solar modules can increase electricity generation by up to 50% compared to traditional single-sided solar modules. There are enough publications proving that these modules can effectively absorb rays reflected from the earth's surface or other objects. In the article, the authors prove that bifacial solar modules are very promising for use in the conditions of central Kazakhstan.
