Performance Investigation of Tempered Glass-Based Monocrystalline and Polycrystalline Solar Photovoltaic Panels

Abstract

Solar photovoltaic (PV) converts sunlight into electricity and is an appropriate alternative to overcome the depletion of conventional fuels and global warming issues. The performance of a PV panel may vary with respect to PV cell technology, fabrication methods, and operating conditions. This research aims at performing an experimental study to investigate the electrical performance of novel tempered glass-based PV panels using two different types of solar cells: monocrystalline and polycrystalline. Tempered glass-based panels are modified forms of commercial PV panels, in which ethylene-vinyl acetate (EVA) and Tedlar are not utilized. This new fabrication method was carried out in this research. Real-time data recordings regarding the PV electrical characteristics ( I - V curve) and solar irradiance were conducted under Malaysian weather conditions on clear sunny days. Results indicated that, at solar irradiance of 900 W/m2, the outputs from the fabricated polycrystalline and monocrystalline PV panels were 67.4 W and 75.67 W, respectively. However, at the highest average solar irradiance (634.61 W/m2), which was obtained at 12:30 PM, the outputs from both panels were 47.87 W and 54.89 W. An I - V curve was obtained for the real-time weather. The electrical efficiencies of the two PV panels were analyzed to be 10.54% and 12.23%.

The Development of Hybrid Cooling Photovoltaic Panel by using Active and Passive Cooling System

“…Mardy Huot et al, [8] had conducted an experiment to study the electrical performance or efficiency of different PV panels which are monocrystalline and polycrystalline. In short, the PV panels provide more electrical output power when the sun irradiation is higher.…”

An Experimental Investigation of Back Flow Cooling Tempered Glass Photovoltaic Thermal System in the Malaysian Peninsula Climate

“…A water-based PVT system frequently used the thermal absorber's heat transfer fluid, which was abundant behind the second layer, to collect heat [8]. Previous studies have been conducted in order to improve the overall performance of fluidbased PVT by constructing the thermal absorber system with different materials and designs, and achieve electrical and thermal efficiencies around 7.4 -15.5% and 42 -83%, respectively [9][10][11][12]. The literature analysis revealed that silicon-based solar cells are the most widely employed in a wide variety of applications with acceptable electrical efficiency ranges.…”
