Abstract
The paper discusses the possibility of solar energy using in the Republic of Kyrgyzstan (RK) for the purpose of electricity distribution. The data sources analysis for the calculation of solar resources was conducted. Due to the scarcity of solar radiation stations on the territory of the RK, international thematic databases containing sufficient information for resource assessment and design were considered. These databases contain the results of long-term ground-based measurements, mathematical modeling and satellite observations. The paper justifies the compliance of a global database with public access NASA SSE to the problem of solar energy resources estimation, and estimates the gross capacity for the territory of the Kyrgyzstan. The authors propose their method of initial evaluation of performance, capital cost and footprint for network photovoltaic plant. The calculations are performed based on monthly averages of daily insolation and the average temperature. To account for the effect of ambient temperature on the output of PV modules, the paper considers two scenarios: the maximum and minimum daily mean ambient temperatures in each month. Evaluate the performance and the cost of electricity are made for plants with a capacity of 5 MW in the case of placing it near the cities of Bishkek and Osh (northern and central part of the RK). At the same time the authors carry out a comparative analysis of the results obtained for several types of silicon photovoltaic modules on the market today: monocrystalline, multicrystalline and the thin film. It is shown that the maximum performance of the network station is provided at an inclination of modules close to the latitude. The temperature dependence of the module characteristics makes the largest contribution to the change in productivity in the summer. The calculations also show that the multicrystalline photovoltaic modules are optimal in terms of price and quality for selected conditions.
