Abstract
Crystalline solar panels are widely used in households and for public road lighting. Mono-crystalline panels are well-known for their higher efficiency and long service life. However, their efficiency decreases as the module temperature increases under consistent solar radiation conditions. To enhance module power generation and efficiency, effective temperature reduction techniques are necessary. This study investigates the use of water and aloe vera fluid as cooling agents for a mono-crystalline photovoltaic thermal (PVT) system. The system was designed with a circulating mass flow rate of 0.016 kg/s or 1 LPM (liter per minute) and tested under the climate conditions of Phnom Penh city, Cambodia. The specific heat of aloe vera fluid was determined and found to be 4236 j/kg·K. The optical efficiency of PVT systems using water and aloe vera fluid was compared in this paper. The experiment results indicate that cooling with aloe vera fluid led to a 0.21% higher electrical power generation compared to water cooling, due to more effective temperature reduction and thermal heat absorption rate of aloe vera fluid is higher than water 32.41%.
