研究目的
Improving the efficiency of the photovoltaic panel through the use of hybrid Photovoltaic-Thermal (PVT) system.
研究成果
The performance of a PVT system has been successfully determined in an experimental study. The theoretical result of the heat transfer simulation of the silicon solar cell was also in good agreement with the experimental results. By using the active cooling technique, the experimental result has shown a significant improvement on the electrical efficiency of PV module.
研究不足
The temperature rise achieved was not significant, attributed to the small panel size and STC conditions.
1：Experimental Design and Method Selection:
A theoretical model was prepared using COMSOL? multi-physics. Water is used as the coolant in the cooling channel, flowing through the copper tubing provided below the photovoltaic panel.
2：Sample Selection and Data Sources:
The size of the panel used is a miniature 110 mm x 110 mm. The experiment was performed indoors under a 1000 W halogen lamp to simulate the Standard Test Conditions (STC).
3：List of Experimental Equipment and Materials:
Copper tubing of 6mm outer diameter and thickness 1mm was used. Copper powder was chosen as a filler between the tubing spaces.
4：Experimental Procedures and Operational Workflow:
The experiment was performed for a period of 30 min, in the meantime steady state temperature for water was reached.
5：Data Analysis Methods:
The results achieved in the experimental set-up are quantified.
