Abstract
The aim of this project was to enhance the efficiency of Photovoltaic (PV) solar panels by implementing a thermoelectric cooling system. PV solar panels can suffer significant efficiency losses due to excessive heat exposure, which leads to thermal dissipation. By maintaining optimal operating temperatures through cooling, the overall efficiency of the panels can be improved. The project incorporated two PV solar panels of the same specifications, the were differentiated by installing a thermoelectric cooling kit in an enclosure while the other panel remained standard.
The experimental approach involved integrating a thermoelectric cooling kit onto the underside of a PV solar panel, with an enclosure designed to expel excess cool air. Data recording over a 7-day period yielded that the unmodified PV panel achieved an average efficiency of 15.28%, while the modified panel with the cooling kit maintained an efficiency of 16.63%, a 1.35% efficiency improvement difference was archived through experimentation. These findings validate the effectiveness of the thermoelectric cooling in the modified PV solar panel efficiency.
Prior research has shown that PV-thermoelectric generator systems with phase change materials can improve overall efficiency by 1-2%. The experimental research 1.35% efficiency outcome gained for the modified panel is consistent with these with prior research, demonstrating the viability of the thermoelectric cooling approach.
