6 FAQs about [The surface of photovoltaic panels is rough]

Why do PV panels have a high dust density?

The variable dust accumulation at any point on the PV surface results in a different distribution of sunlight entering the PV array, increasing the possibility of a hot spot that damages the PV panels 8. Higher dust density reduces PV short-circuit current, open-circuit voltage, and output power.

What is the roughness of a solar cell coating?

In addition to maintaining low surface energy of materials, the roughness of the coating has to be maintained below 100 nm in order to avoid scattering of light as it directly affects the transparency and yield of the solar cell.

What factors affect soiling of photovoltaic panels?

Soiling of photovoltaic panels is greatly affected by environmental factors (rainfall, humidity, wind, and temperature), photovoltaic module factors (installation, inclination angle, and surface material), and dust factors (particle diameter and type of dust) as represented in Fig. 2.

How to reduce soiling issues on PV panels?

In this study, the sol–gel method was used to create rough surface hydrophobic coating to reduce soiling issues on PV panels. A solution was prepared using three different materials including vinyltriethoxysilane (VTES), tetraethoxysilane (TEOS), and tetrabutoxytitanate (TTBU) called VTT (VTES–TEOS–TTBU) sol as the organic–inorganic hybrid sol.

How does soiling affect PV performance?

3. Shading by soiling on PV performance The term ‘soiling’ is used to describe the accumulation of snow, dirt, dust, leaves, pollen, and bird droppings on PV panels. The performance of a PV module decreases by surface soiling, and the PV power loss increases with an increase in the quantity of soil on the PV module.

How does soil affect the performance of a PV module?

The performance of a PV module decreases by surface soiling, and the PV power loss increases with an increase in the quantity of soil on the PV module. Thus, the accumulation of soil on the PV module can lead to a significant decrease in energy produced by the PV module.
