How effective is the hydrophobicity of photovoltaic panels

The exploration of several soiling mitigation methods for PV panels underscores the ongoing efforts to enhance the efficacy of solar energy systems. From advanced cleaning techniques to the application of antireflective coatings, the research and development in this area contribute significantly to overcoming the challenges posed by dust, dirt .

The efficiency of dust prevention reaches 65.85% when the wind direction is 0°. Currently, solar photovoltaic power generation technology is developing rapidly around the world to achieve the objective of carbon neutrality. The deposition of dust on solar photovoltaic modules is one of the main reasons for the decline in power generation .

The PCE of PV panels covered by this coated glass is significantly higher than that of flat glass, and the device can achieve an excellent PCE recovery rate. The armor formed by the inverted pyramid structure protects hydrophobic materials, resulting in superior stability.

This study was conducted to enhance the performance of PV solar panels by reducing the dust accumulation on panels' surfaces over time, thereby reducing cost, effort, and water consumption.

Photovoltaic (PV) power generation is a clean energy source, and the accumulation of ash on the surface of PV panels can lead to power loss. For polycrystalline PV panels, self-cleaning film is an economical and excellent solution.
