【 摘 要 】

During the electricity generation of photovoltaic (PV) cells, large fraction of solar radiation gets converted into heat which raises the temperature and decreases the electrical efficiency. In order to reduce the heat accumulation, there are several methods that can be applied to cooling the solar panel. One of the simple and efficient approaches is to use the phase change materials (PCM) as a heat absorber. This research is the designed and constructed a housing container for filling up palm wax that is used as a PCM. The designed PCM containers are groove type, tube type, and fin type. Experiment was to compare the PV cell that installed the designed with PCM (test module) and with non-installed PCM containers (reference module). Exposure time for solar radiation is carried out from 9:00 AM to 5:00 PM at an atmospheric condition in Khon Kaen, Province of Thailand (latitude, 16° 25' 50" N and longitude, 102° 37' 0" E). Results showed that when the time is at 11:00 AM to 1:00 PM, solar radiation yield the most constant value. It was found that the designed fin type achieved the most outstanding heat reduction when compare with other designed prototype. The designed fin type has also reduced an average temperature by 6.167 °C and the average electrical efficiency is increased by 4.858 per cent.
