Sažetak
The nanoparticle-enhanced phase change material (NEPCM) has a good potential for improving the energy conversion efficiency of photovoltaic (PV) system by increasing the thermal conductivity of phase change material. In this paper, a photovoltaic panel coupled with nanoparticle- enhanced phase change material (PV-NEPCM) was numerically investigated considering different PCM melting temperatures (ranging from 5 to 50°C with 1°C intervals), PCM layer thicknesses the range of 1-50 mm with 1 mm intervals) and nanoparticle volume fractions (1%, 3% and 5%). Measured monthly-averaged climatic data for Ankara was used to analyze the effect of investigated parameters on the conversion efficiency, cell temperature and electricity output of PV-NEPCM system. The results showed that the combination which provides the highest improvement (1.72%) is NEPCM with PCM melting temperature of 20oC, PCM thickness of 50 mm and nanoparticle volume fraction of 5%. The total annual electricity output of PV panel, 9585 Wh/m2year, can be increased to 9750 Wh/m2year by incorporating NEPCM with optimized parameter.
