| Abstract [eng] |
The final thesis investigates the efficiency of water-cooled solar modules by modeling the operation of cooled and uncooled solar modules on a pitched roof and conducting a test to validate the modeling results obtained. The review section examines the heat impact on the efficiency of solar modules and reviews solar module cooling technologies and their impact on solar module efficiency. During system modeling, the angle of inclination of the solar modules towards the horizon, azimuth direction, and volume of the water reservoir are varied. After performing iterative calculations, the annual cooling water impact on the efficiency of solar modules is evaluated, considering the electricity generation while assessing the energy consumption of the water pump, the efficiency difference between cooled and uncooled modules. Additionally, the overall cooling benefit is assessed. Upon conducting the test, the correspondence of the meteorological package used by PVsyst software to the actual data provided by the Lithuanian Hydrometeorological Service is validated. Furthermore, the PVsyst validation of solar module electricity generation is based on the analysis of 3 years of historical data from 5 random solar power plants. Finally, the validation of the results of modeling cooled solar modules is performed based on data collected during the test on August 6 and September 7 in a year 2023. |
