6 FAQs about [The surface of the solar photovoltaic panel is scratched]

Do solar panels get scratched?

Where a solar panel is concerned, once it gets so scratched it no longer performs, you must replace the entire thing. One of the best ways to prevent scratches from occurring is to regularly clean the surface of your solar panels with water. This stops dirt from accumulating, which is when scratches can easily occur.

Can a scratch affect a PV panel's durability?

it just isn't acceptable. I really do not agree that the scratches can in any way affect the panel's durability. All MCS accredited panels are encapsulated in very thick glass and a scratch isn't going to make water go anywhere near the PV cells. I would suggest you ask for a replacement.

How do I prevent scratches on my solar panels?

One of the best ways to prevent scratches from occurring is to regularly clean the surface of your solar panels with water. This stops dirt from accumulating, which is when scratches can easily occur. Also, keep the surrounding vegetation down.

Can a scratch on a PV panel cause water damage?

All MCS accredited panels are encapsulated in very thick glass and a scratch isn't going to make water go anywhere near the PV cells. I would suggest you ask for a replacement. If the modules were already scratched when the installer received them, the module warranty should cover that.

What happens if you damage a solar panel?

Solar panels (good ones anyway!)have hydrophobic and antireflection coatings on them to improve the transmittence of light (by about 8%) and the panels ability to self clean. If you damage this coating water can get underneith. this then causes lifting of the rest of the coating, causing a delaminating effect over the surface of the panel.

Does dust deteriorate the productivity of solar PV panels?

The productivity of solar PV panels deteriorates by the deposition of dust on front surfaces (Al-chaderchi et al., 2017).
