The influence of some natural factors on efficiency of operation of photoelectric elements under conditions of North Kazakhstan

Abstract

The article presents the results of studies of some natural factors on the productivity of solar cells. In the study of output characteristics, the dependence of the generation of electrical energy on the number of incident solar radiation on photoelectric converters was obtained. From these characteristics it can be precisely said that the dependence of the operating current and voltage on solar radiation and temperature is not completely proportional. The humidity exerts the most insignificant influence on the solar installation. Particular attention should be paid to the dependence of voltage changes on the magnitude of solar radiation. It has been revealed that in low power plants the influence of temperature will not play an extremely important role on the output parameters, but at higher powers the losses associated with the increase in temperature will be correspondingly large. The generation of electrical energy from solar photoelectric converters depends on many factors, not only on incoming radiation, but also on aspects such as: the location of the solar transducer to the sun, pollution of solar cells, icing and snow cover of solar cells. In this scientific work was made an analysis of the effect of snow precipitation on the productivity of solar cells in the characteristic climatic conditions of North Kazakhstan.

Experimental Studies of the Developed Method for Determining the Insulation Parameters in an Asymmetric Network by a Voltage up to 1000 V at Mining Enterprises

“…To prove credibility, according to estimation of errors set out in [4,5], it is necessary to make at least four measurements. In this case, we took eight measurements with a time interval of 0.5 hours.…”

“…To compare the results of the developed method and the ammeter-voltmeter method, error estimation was produced [4,5] and the following parameters are determined (obtained results are summarized in table 3):…”
