Efficiency Enhancement Of A 20-Watt Monocrystalline Photovoltaic Solar Panel Using Integrated Techniques

The study shows an attempt to increase the efficiency of the solar panel by combining 3 approaches in enhancing its performance. Factors that affect its efficiency are the intensity of the light falling on it and the temperature effect. The 20-watt monocrystalline solar panel is subjected to have an installed cooling unit on both surfaces with mirrors set at 60° to horizontal in each sides as light concentrators. The panel can be set-up into 8 different techniques which are the conventional panel, panel with front coolant, panel with back coolant, panel with front and back coolant, panel with mirrors, panel with mirrors and front coolant, panel with mirrors and ack coolant, panel with mirrors and front and back coolant. It composes of a combination of 2 different techniques, the conventional panel and coolant, and a combination of all the 3 techniques, the conventional panel, coolant and mirrors. The study conducted experiments to prove the increase of efficiency of the panel through increasing the light harvested, while decreasing its temperature. The efficiency is measured using Practical Testing Condition (PTC). The result for the mentioned experimental set-up shows that the panel installed with the combination of all the 3 techniques resulted with highest increase in efficiency of 25.29%.
