Abstract

The article presents studies of double-sided solar modules in Kazakhstan. To conduct an experimental research of double-sided solar modules efficiency in the climatic conditions of Central Kazakhstan we have created an experimental solar power plant (SPP) located on the territory of Karaganda State Technical University. The solar power plant consists of four photovoltaic modules of KZ PV 270 M72 type and four photovoltaic modules of FSM-185D type. The rotary system was not used; solar panels are southward (directed to the south). The comparison was made with the solar power plant without orientation system which uses four photovoltaic modules of KZ PV 270 M72 type produced by Astana Solar LLP.


The statistical analysis of information with an assessment of parameters of distribution and criteria for processing of results of scientific experiment is carried out. The correlation and regression analysis is performed. The least square method (coefficient calculation) is used in data processing. We have developed the computational model simulating the SPP by means of which the theoretical averaged values of energy amount generated in kWh/day have been obtained, and the actual values have been received by in-use measurements of SPP parameters within a year. The results of this work showed that the use of double-sided solar modules in Kazakhstan is very promising and can be a decisive factor for their widespread use with the tendency to lower prices.
