Abstract
The article presents the results of research on the efficiency of photovoltaic (PV) modules cooled with water. The aim of the experiment was to improve the working conditions of solar modules. A temperature decrease was obtained for the PV module by pouring cool tap water onto the upper surface of the modules, either in imitation of rain or as a water film. The power of the cooled and non-cooled devices were then compared. The temperature of the cooled modules dropped to almost 25 °C, whilst the temperature of the non-cooled module was 45 °C. The best results were achieved by cooling modules with a water film, since there were no water splashes, and the continuous cooling of the surface leads to a 20% increase in power. During the test, the non-cooled module attained a maximum power of 105.3 W/m2, compared to 125.5 W/m2 for its cooled counterpart. Cooling the module, therefore, resulted in a power increase of 20.2 W/m2. The results of the work may be of particular interest for small installations, especially because it cleans the modules while providing an increase in power.
Highlights
Recent years have seen significant developments in the technology used to convert solar energy into a reliable power source [1,2,3,4]
It is important to see whether the effect of PV cooling is discernible in colder conditions. This is why the purpose of our research and analyses was to determine if cooling PV modules can improve their work parameters and maximize the energy yields achieved during the operation of PV panels under central European
At 14:11, the reference module was shaded by people for a while, but it had no consequences for the results
Summary
Recent years have seen significant developments in the technology used to convert solar energy into a reliable power source [1,2,3,4]. The effect of sunlight method, i.e., the one which allows greatest power production density to be attained It is on the dark blue or black surface of the device (with a relatively high radiation absorption coefficient) important to bear in mind the discrepancy between the power obtained when a panel works in real determines the increase in itspower, temperature. Krauter,and where highest power by bothconversion high valuesthroughout of solar radiation an ambient temperature, he showed thatare thecharacterized efficiency of energy the dayand increased by approximately which makes it impossible to maintain a low temperature value for the PV panels [7].water Another way to reduce the temperature of the PV module is back surface cooling.
