“…One of the most widely used of these energy sources is solar energy. According to [1], solar energy is a more promising and high-tech energy source than wind and hydropower. Common methods and devices for the use of solar energy include solar photovoltaic panels, solar collectors, solar batteries, and solar ponds, which are considered alternatives in low-potential heat accumulation.…”

This article is devoted to the experimental study of the temperature regimes of the solar pond in the southern climatic conditions of Uzbekistan. The research was conducted in an experimental version of a solar pond that accumulates low-potential heat. According to research, when taking heat from a salt solar pond, without a coating on its upper surface and comparing the results of a glass-covered experiment is 10-15% higher than that of a glass-covered experiment, when the ambient temperature is 34 °C and solar radiation is 973 W/m2 it is scientifically based that the temperature of saline solar pond water with a concentration of 25-30% rises to a temperature of 53 °C in the lower part of the pond and that the energy storage efficiency of the lower convective zone of the solar pond increases in parallel with increasing solar radiation

Nowadays, solar energy is one of the important clean energies through converting the light sun into electricity by photovoltaic solar cells which is a semi-conducting material. Solar radiation is one of the most important factors in determining the amount of produced energy through absorbing it by the solar cells. On the other hand, heat is one of the sources of energy loss if it rises more than the prescribed limit, thus reducing the amount of electrical energy generated and reducing production efficiency. Therefore, this paper focuses on designing, testing and comparison the photovoltaic panel system (PVS) with and without Active cooling process via water in Baghdad environments. The active cooling system (ACS) was placed behind the solar cell in order to absorb the generated heat that is isolated from the environment. The testing of both models was conducted in April 2021 in Baghdad. As a result, PVS with cooling performed well compared with uncooled, where uncooled model at highest panel temperature produced about 8 % from operation efficiency. While, the ACS worked on increasing the system performance up to 16.5% by decreasing the panel temperature. The efficiency conversion has recorded to be 50% and 52% at two mass flow rates. Water flow rate increased the heat transfer through cover glass which led increasing the efficiency. Finally, ACS for PVS can improve the efficiency by about 12% as an average value. At high temperature environment, cooling system should be employed to get better PVS performance and reducing the payback period.

The development of solar energy allows considering a possibility of using solar panels as the main power source for mobile machines. Especially for the machines used in open sunlit spaces, for example, for sprinkler machines. This article discusses a problem of justifying the parameters of a power supply in the form of accumulator batteries charged from solar panels while ensuring the required duration of operation of a sprinkler machine. Studies show that the duration of operation depends on the time of day when a sprinkler machine is started,its accumulator battery parameters, duration of the recovery charge, climatic zone and the area of the solar battery. Dependence of these parameters was found on the duration of operation of the electric drive of the support trolley of one section of the sprinkler machine, and a graphical solution to this problem is provided.
