Power Enhancement of Solar Cell Panel with Planar-Reflector in Conjunction with Temperature-Controlled Water Cooling System

This research investigates the enhancement of electrical power in solar panels by using planar-reflector with
an aluminum tape surface, combined with a water cooling system controlled by a temperature control unit.
This study analyzes the direction of radiation reflection and calculates the solar radiation values impacting the solar panel’s surface to select the appropriate length and installation angle. After that, experiments in
conjunction with a water cooling system set at 45°C, 55°C, and 65°C to measure power output. From the
calculations, a planar-reflector length of 1.20 meters and an installation angle of 126° were chosen. The
experiments revealed that installing the planar-reflector causes power loss in the morning and evening due to shading over the solar panels. During periods without shading, the testing panel generated more electricity than the reference panel. At a solar radiation intensity of 900 W/m², the installation of the planar-reflector increased electrical power by 42%. Moreover, combining the planar-reflector with the cooling system at 45°C, 55°C, and 65°C increased electrical power by 50%. When considering solar radiation intensities above 900 W/m², the combination of the planar-reflector and cooling system showed a higher rate of increase in electrical power compared to the installation of the planar-reflector alone.
