The operating temperature of the photovoltaic (PV) module plays a major role among the parameters affecting the energy yield of photovoltaic (PV) power generation systems. This paper compared the requirements of Nominal Operating Cell Temperature (NOCT), which is used to estimate the PV module operating temperature according to IEC 61215:2005, with those of the recently revised IEC 61215: 2016 Nominal Module Operating Temperature (NMOT). Through this, each feature of the parameters used to calculate the NOCT and NMOT could be determined, and it was assumed that the NMOT is lower than NOCT. And, among the parameters, the wind speed was found to be a significant variable affecting the temperature, and non-linear clusters and skewed data are improved if some data in the morning were deleted considering the period of module activation. Moreover, it is found that the method summing up the daily data for the calculation can reduce the correlation and deviation of NMOT.

This chapter gives a small part of the work carried out in Uzbekistan on the use of solar and wind energy. It is, of course, impossible to list all the work performed in this area since the 1930s. Therefore, the author drew attention to the part that is associated with the author's direct scientific and technical work. Here are the works related to the Big Solar Furnace of Uzbekistan, the operation of a modern automated weather station, the measurement and use of wind energy. The socio-economic development of the republic largely depends on a stable electricity supply. Renewable energy sources play an important role in this. In this sense, the construction of a wind power plant with a total capacity of 1,500 megawatts represents a change in the traditional energy system of the Republic of Uzbekistan, which has entered a new energy era.

“…There has been overwhelming researches and studies regarding utilization of solar energy for different purposes, mainly for heat energy and electricity production [3][4][5][6][7][8][9]. In the scientific work [10] two types of photovoltaic, monocrystal and polycrystal, modules were tested under Tashkent region environmental condition to determine the influence external condition on photovoltaic energetic performance. It was found that both, monocrystal and polycrystal, modules have average value of efficiency 13.3 %.…”

The energetic performance of autonomous solar powered refrigerator is analyzed. In this refrigerator, the solar energy is converted into electrical energy by a photovoltaic (PV) array, then the generated electrical energy is used to power a vapor – compression system which produces cooling energy at its evaporator. The evaporator is sunk to the water so that produced cooling energy is used to formation water ice, thus accumulates cooling energy in the form of ice. While, compressor is working during the daylight hours, cooling energy is produced. During the night, the cooling energy comes from latent heat of fusion of ice which is collected in day time. The results of experiments showed that not only the solar energy has influence on the energetic performance of solar refrigerator but ambient temperature is also crucial factor in this case.
