研究目的
Investigating the performance of a solar parabolic dish photovoltaic-thermoelectric generator under realistic outdoor circumstances and analyzing the effect of focal distance.
研究成果
The study demonstrated that a solar parabolic dish PV-TE generator can effectively convert solar energy into electrical energy with an overall efficiency of 19.65% at the optimal focal distance of 57 cm. The system's ability to cool itself and the TE generator using the PV module's output enhances its efficiency and reliability. This concept is suitable for low-power applications such as wireless sensors due to its environmental friendliness and noiseless operation.
研究不足
The study was conducted over a limited period of 3 days, and the tracking of the sun was done manually, which may not capture the full range of operational conditions. The system's performance in different weather conditions and over longer periods was not evaluated.
