On the Possibility of Cooling and Cleaning the Surface of a Photovoltaic Battery Using the Venturi Effect

The results of an anhydrous cleaning and cooling model of a photovoltaic battery (PVB) using the Venturi effect are presented. The Venturi tube is a truncated cone, the speed of air movement in which depends on its height and the ratio of the areas of bases δ. The highest air flow rate is achieved at 1 < δ ≤ 1.5. The limiting temperature of PVB cooling is practically independent of the pipe height. Air flow generated by the Venturi tube removes medium and fine dirt particles.
