研究目的
To evaluate the potential for the introduction of the PV/T technology into Gujarat, India, and to improve the electrical efficiency of PV modules by extracting heat through water circulation.
研究成果
The combined PV/T system achieved a combined efficiency of 79.18%, which is higher than the individual efficiencies of the PV module (13.56%) and CPC (53.92%). This indicates a promising future for solar-based power systems in both domestic and industrial applications.
研究不足
The study is limited by the specific geographical location (Gujarat, India) and the time frame (March-April 2016). The efficiency of the system may vary under different climatic conditions and with different materials or designs.
1：Experimental Design and Method Selection:
The study integrates photovoltaic and solar thermal technologies into a single solar energy device to generate electricity and heat energy simultaneously.
2：Sample Selection and Data Sources:
The experiment was carried out at A D Patel Institute of Technology, V V Nagar, Gujarat, during March-April
3：List of Experimental Equipment and Materials:
20 The setup includes a PV cell with a CPC, water tubes for heat extraction, and materials like mild steel, stainless steel, reflecting glass, copper, and glass wool.
4：Experimental Procedures and Operational Workflow:
The system was tested with water flow rates of
5：03 kg/sec and 016 kg/sec to determine thermal and photovoltaic performance. Data Analysis Methods:
The performance was analyzed based on thermal and electrical efficiency measurements under varying solar intensities.
