研究目的
To investigate the effect of photovoltaic thermal outlet water temperatures and solar cell temperature on both electrical and thermal efficiency for different range of inlet water temperature.
研究成果
The research describes the design and analysis of a PVT system for producing electricity and thermal energy. The performance of the PVT system is influenced by several factors including PVT’s materials, design, ambient temperature, inlet and outlet fluid temperature and PV cell temperature. The study achieved an average thermal and electrical efficiency of 65% and 13.7%, respectively. Further research is required to determine the optimum location for PV cell when the partial PV surface is applied and to optimize the outlet water temperature.
研究不足
The study was based on a mathematical model with some parameters assumed due to missing information in the experiment. The model validation showed some discrepancies with experimental data, indicating areas for further optimization.
