Pulsating Heat Pipe offers an effective passive cooling method to mitigate the efficiency drop in solar photovoltaics caused by excessive temperature. In the present work, single-loop Pulsating Heat Pipe using methanol and ethanol working fluids with filling ratios of 35%, 45%, and 55% with initial pressures of 30 kPa, 50 kPa, and 100 kPa were tested at power input of 13.8-60 W. The factors that affect startup performance and thermal resistance were studied experimentally on a lab scale. The results demonstrated that Pulsating Heat Pipe charged with methanol shows superior startup performance and lower thermal resistance compared to ethanol. Experimental results indicate that a 35% filling ratio provides the fastest startup condition, while the best thermal performance is obtained at 45%. Decreasing the initial pressure on Pulsating Heat Pipe can accelerate startup and improve thermal performance. Integrating Pulsating Heat Pipe with the solar panel can potentially reduce the panel temperature by up to 5.1 °C.
