Today, photovoltaic systems are widely used, but the tasks of increasing the efficiency and reducing the cost of such systems are still relevant. Among many methods for increasing photoelectric efficiency, the method of active water cooling stands out, the use of which is especially important for Vietnam and other countries with a tropical climate. This article is devoted to the analysis of methods of active water cooling, the analysis of the experimental design of photovoltaic modules and systems, as well as methods to increase efficiency through the use of water cooling.high compared to people's lives. Therefore, it is necessary to study the performance improvement as well as reduce the cost of the photovoltaic system. Among many methods of improving photovoltaic efficiency, active water cooling is quite effective and low cost. This paper focuses on the analysis of active water cooling methods, experimental layout, as well as improved performance when applying cooling.
