“…Production of potable water by ASS costs 0.75 rupees per liter and 0.85 rupees per kilowatt hour of electricity. Thermosiphon [29,30] and force circulation [31][32][33] are the two primary types. There are many parts that make up a flat plate collector, such as the glass cover [28,[34][35][36], absorber plate [37][38][39], air gap [40][41][42][43], riser pipe [44][45][46][47][48], frame, and insulation [49][50][51].…”

All Earth's life forms depend heavily on water. Despite the critical importance of fresh water in the modern world, water pollution caused by industry and increasing urbanization has significantly reduced the amount of pure water available on Earth. Changes in global climate and seasons also contribute significantly to the depletion of fresh water resources. Population growth over the past few decades has increased the demand for safe drinking water. Multiple water-borne diseases can result from drinking contaminated water, and depending on the level of pollution, this could even be fatal. There are several ways to purify polluted water, but solar distillation is the most cost-effective and environmentally friendly option because it mimics the hydrological processes seen in nature and can be powered by the sun alone. Solar stills provide drinkable water and don't call for any special expertise to operate or maintain. An integrated PV/T solar still is a welcome solution for distant locations that already struggle with access to safe drinking water and dependable electricity. According to research, a passive solar still produced 2–5 kg/m2 of fresh water daily whereas an active solar still connected to a PV/T collector could produce 6–12 kg/m2 of fresh water daily. In this paper, we provide a complete investigation of the solar still coupling and PV module coupling levels at the moment.

“…The practical significance of the results of this work indicates that the presence of nanoparticles on the upper glass of the collector increases thermal efficiency, profitability and service life. In the article [22] was discussed the results of experimental measurements, performance comparison and managing control system for a flat solar collector with thermosiphon circulation and a flat solar collector with a special chemical coating. There has been developed the master controllers control module, which receives data from temperature and lighting sensors obtained during operation.…”

In this study, a flat solar collector with a thermosyphon 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 collected over several sunny and cloudy days. The dynamic response of the system to changes in solar insolation is studied and analyzed. It has been found that such systems can provide enough energy to meet the need for hot water, contrary to the erroneous opinion of local residents. The system operates using six sensors (temperature sensor, water flow sensor, pressure sensor, coolant temperature sensor in the heater tank, coolant temperature sensor in the heat exchanger and outdoor temperature sensor). Six sensors are controlled with a programmable logistics integrated circuit (FPGA) STM32 circuit designed to monitor the entire solar system, and the actuators include power relays. The temperature readings are sent to the ESP 32 module. The ESP 32 module is synchronized with six sensors connected to the STM32 FPGA, with six electrical wires programmed in C++, which after processing the temperature, date and time data received from the real-time clock. After the whole process, all sensor data is sent to the ESP 32 module, where data is sent to the database. During the experiment an electric energy consumption savings of about 1% was achieved due to the control signal in the controller which had a significant impact on the service time of the equipment.

“…Research was carried out by modeling thermal processes in systems with solar collectors [12][13][14][15], as well as through wide-parameter experimental studies [10,[17][18][19][20]. Modern designs of solar collectors make it pos30the type of solar collector and its technical characteristics necessary for heat supply systems should be made on the basis of comparison and in-depth analysis [21][22][23][24]. At the same time, the effective operation of such systems, especially in buildings of a high energy efficiency class, is possible thanks to control and regulation systems [25,26].…”

The proposed Trombe wall design is an innovative and effective solution for addressing issues related to building energy efficiency. The Trombe wall can help reduce a building's energy consumption, provide optimal indoor temperature, and minimize the building's environmental impact by utilizing renewable energy sources.The article deals with the study of the heat-air characteristics of the Trombe Wall, which performs the functions of external protection of a modular house, with the aim of further evaluating the possibility of using it as a hybrid protection with additional heating and ventilation functions assigned to it. The results of experimental research conducted on one of the elements of external protection of a modular house in the form of the Trombe Wall are presented. The experimentally obtained graphic dependences were compared with the calculated data and the convergence was evaluated. The proposed design allows you to organize air exchange in the premises with a multiplicity within 1-1.5 h −1 , and also provides an opportunity to provide additional thermal power in the amount of 250 W/m 2 . The article presents the results of experimental studies that allow to evaluate the thermal characteristics of the proposed design of external protection for a modular house. These results indicate that with the given geometric dimensions, in particular with a volume of 14 m 3 , the thermal power utilized by the Trombe wall is within 0.2-0.7 kW.
