Performance Investigation of Photovoltaic Thermal System Incorporating Nano Coolant - Review

Photovoltaic (PV) modules experience a reduction in electrical performance when their surface temperature rises beyond the recommended operating range. Most of the incident solar energy is converted into heat rather than electricity, leading to efficiency loss and reduced panel life. This project investigates a photovoltaic-thermal (PVT) system using nanocoolant-based cooling to regulate PV surface temperature and enhance overall performance. Experimental studies were carried out under outdoor conditions to evaluate the effect of cooling on voltage, current, power output, and electrical efficiency. The results demonstrate that controlled cooling significantly reduces panel temperature, improves voltage output, and increases electrical efficiency compared to a conventional PV system. The proposed approach offers an effective solution for performance enhancement and thermal management of solar panels
