6 FAQs about [The photovoltaic panel coating has spots]

Why do photovoltaic panels need a transparent coating?

When sunlight shines on the photovoltaic panel, part of the visible light will be reflected, and the rest will be converted and utilized. Therefore, the transparency and anti-reflection of the self-cleaning coatings applied on photovoltaic modules cannot be ignored.

Why do photovoltaic panels need a self-cleaning coating?

The self-cleaning coating has attracted extensive attention in the photovoltaic industry and the scientific community because of its unique mechanism and high adaptability. Therefore, an efficient and stable self-cleaning coating is necessary to protect the cover glass on the photovoltaic panel. There are many self-cleaning phenomena in nature.

What factors should be considered when applying photovoltaic coatings?

When applied to photovoltaic modules, it is crucial to consider the factors such as self-cleaning, transparency, anti-reflection, anti-icing, and durability. In future research, it is significant to improve the transparency, durability, and self-cleaning properties of coatings.

Do PV modules have anti-reflection coatings?

These reflection losses can be addressed by the use of anti-reflection (AR) coatings, and currently around 90% of commercial PV modules are supplied with an AR coating applied to the cover glass , . The widespread use of AR coatings is a relatively recent development.

How to choose the best coating thickness for photovoltaic modules?

The coating is superhydrophobic, with a contact angle of approximately 159° and a transmittance of 85% (Fig. 12). Thus, when applied to photovoltaic modules, the best coating thickness can be obtained by controlling the number of coating layers. This method is easy to implement and cost-effective.

Does dust affect the tilt angle of PV panels?

Ashhab and Akash (Akash, 2016) studied the dependence of PV panels' performance on dust accumulation in addition to tilt angle; their results indicated that the existence of dust in a certain area may modify the optimal tilt angle.
