“…The change in the height of the Sun in the sky during the year is determined by the recession of the Earth's axis, which is responsible for the declination of the Earth's axis relative to the ecliptic plane during the year. During the day, the Earth also rotates around its axis, describing a full circle; this movement is the cause of sunrises and sunsets [11][12][13][14][15].…”

This is called "azimuth correction of the Sun".…”

The generation of electricity by solar photovoltaic batteries depends on the angle of incidence of sunlight and is maximum when this angle is 90 degrees, i.e., rays fall strictly perpendicular. The greater the deviation from the 90-degree angle, the more radiant energy is reflected rather than extinguished by the solar modules. Therefore, it is especially important to correctly orient the surface of solar modules and set the desired inclination angle. To place photovoltaic panels on the site of a solar power plant, it is necessary to calculate their mutual shading, considering the design and dimensions of one solar cell panel and the method of its installation on the ground at a certain calculated angle.

“…According to the European Energy Agency "Solar Power Europe", it took only 10 years to increase the capacity of solar power plants from 100 GW in 2012 to 1 TW by the end of this year. Even greater acceleration of the commissioning of new capacities of photovoltaic power plants (PVP) is expected on a global scale; for example, they predict a twofold increase in just three years, reaching 2.3 TW by 2025 [1][2][3][4]. Uzbekistan also pays great attention to the development of renewable energy sources.…”

This article discusses modern schemes of using solar energy in the systems of the Ministry of Water Management. The analysis of electricity generation by photovoltaic water-lifting stations by months has been carried out and the effectiveness of their use as a reliable source of power supply to pumps has been proved. The payback period of solar water lifting systems is calculated. Calculations show that the payback period for solar water-lifting systems, considering only the cost of saved natural gas and carbon dioxide emissions is no more than 6 years. It should be noted that the life of the PVP is more than 20 years. Tax breaks on property and land use, provided for by the legislation of the Republic of Uzbekistan, further shorten the payback period.
