Considering multiscale surface texturing of PV panel glass cover, represented generically as fractal surfaces, the study comprehensively investigates the effect of texturing on the module’s optical, thermal, and overall performance, as well as the surface’s wettability characteristics.
Measured reflectance, surface roughness, and solar beam spread from several PV modules. We attempted to correlate the beam spread to the surface roughness. Developed a design method to minimize glint/glare from PV modules and maximize transmittance. Results were incorporated in the SGHAT code.
When exposed to sunlight, the Y6-NanoSH coated photovoltaic panel raises its surface temperature, inhibiting the growth and accumulation of ice and frost on its surface. This is achieved through a combination of photothermal emission and superhydrophobic repellency, which promotes the evaporation and rolling away of water droplets.
Texturing the PV panel glass cover is an effective means of reducing solar radiation reflection and providing surface hydrophobicity to reduce dust accumulation.

6 FAQs about [The photovoltaic panel surface has frosted texture]
Does solar photovoltaic panel cover glass have a natural reflectance?
Although solar photovoltaic panel cover glass is highly transparent, it has a natural reflectance in the visible wavelength range. An effective method to increase the effectiveness is to reduce the optical loss and natural reflectance via antireflection (AR) coatings.
Do solar panels have antifouling properties?
Scientific Reports 12, Article number: 1675 (2022) Cite this article Soiling of photovoltaic modules and the reflection of incident light from the solar panel glass reduces the efficiency and performance of solar panels; therefore, the glass should be improved to have antifouling properties.
Can reflected light improve the efficiency of PV panels?
Reflected light represents uncaptured energy; therefore, decreasing the proportion of reflected light represents a promising approach for increasing the efficiency of PV panels. Textures on the front surfaces of the panels are often used to reduce the reflectance; however, it will be significant if the surfaces achieve lower reflective light.
What factors affect the power difference between coated and uncoated PV panels?
It was found that conditions such as cloudiness, rainfall, and muddy stains significantly influenced the power difference (ΔP) between the coated and uncoated PV panels. The increase in ΔP was due to the improved dust removal from the super-hydrophilic surface of the coated panels.
What is the best cooling pattern for a photovoltaic module?
Analysis of radiative cooling for different patterns in the surface of the glass. Holes were the best cooling structures for temperatures below ambient at daytime. Pyramids, the best cooling pattern at daytime for a temperature 15 °C above ambient. Photovoltaic module 1. Introduction
How to evaluate thermal performance of glass textured with different patterns?
