Passive cooling using perforated aluminum plate to improve efficiency on monocrystalline of 100 Wp photovoltaic

Abstract

Many researchers had applied various cooling techniques to reduce the operating temperature of PV cells so it will not exceed the temperature limit. If the operating temperature is exceeded, it can worsen the performance of the PV panel system. Passive cooling is one of the cooling techniques to reduce the operating temperature and increase the efficiency of the PV panel. Cooling operation without the addition of electrical energy is a new original idea, namely passive cooling which uses perforated aluminum plates mounted behind the PV panels. Research that has been carried out using perforated aluminum plates, hole diameter of 5 mm, hole spacing of 200 mm, and total holes of 1551 can increase efficiency by up to 57.64 percent on 100 WP monocrystalline PV panels.
