Abstract
The performance of photovoltaic module (PV) situated outdoors suffers from high temperature. When the high temperature of surrounding atmosphere is increased, the generation of electricity power drops rapidly. This paper is concerned with the temperature compensation technique of the cooling PV cell by using the phase change materials (PCMs). PCM used in this research is palm wax with the melting point at 52 °C. We used a stainless steel container that is designed with three types of installation (fin type, groove type and tube type) to cover the surface area for heat exchanger purpose. The heat exchanger is installed at the back of PV cell. The test is conducted for all day (9AM-5PM) under the climatic condition of Khon Kaen, Thailand (latitude, 16° 26’ 20” N and longitude, 102° 49’ 43” E) during winter. It was found that the PV cell that is used PCMs installed container with fin type was able to produce more electric power to an order of 8.178 per cent than the controlled reference module.
