In this study, a flat solar collector with a thermosiphon was tested in the laboratory of the Institute of Information and Computing Technologies of the Ministry of Education and Science of the Republic of Kazakhstan, located in Almaty (77 degrees east longitude and 43 degrees north latitude). Experimental data were concentrated on many sunny and cloudy days. The dynamic reaction of the system to changes in cloudless insolation was studied and analyzed. It has been found that such systems can guarantee sufficient energy to meet the needs of hot water, contrary to the false opinion of residents. The design functions using six meters (temperature sensor, water flow converter, pressure converter, cooling water temperature converter in the heater tank, cooling water temperature converter in the heat exchanger, and external air temperature sensor). Six counters are controlled using a programmable logistics integrated circuit (FPGA) STM32, designed to monitor the entire solar system, and serviceable mechanisms connect power relays. The temperature data is sent to the ESP 32 device. The ESP 32 device is synchronized with six sensors connected to the STM32 FPGA, supported by six galvanic wires programmed in C, which, after processing the provided information about temperature, date, and time, work according to the clock of the current time. After all the work is completed, all the counter data is sent to the ESP 32 module, from where the information is sent to the database. During the experiment, due to the control signal in the controller, a significant impact on the service life of the equipment was shown.
