6 FAQs about [There are scratches on the glass surface of the photovoltaic panel]

Why do solar panels have scratches on the glass cover?

On average, small and large scratches on the glass cover of solar modules are found during more than 70% of independent 3rd party quality inspections, such as those performed by Sinovoltaics Consultancy Services. This is a major and prevalent quality issue.

Why do solar panels get scratched?

Even the smallest debris, like twigs, leaves, or dirt, can cause small micro-scratches on your solar panels. The scratches from fallen debris can dramatically lower your panels’ energy output. The scratches can hinder sunlight from shining directly onto the cells, and that decreases the amount of solar energy each panel is able to absorb.

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.

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.
