6 FAQs about [There is a scratch behind 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.

Are scratches on solar panels a problem?

At the time, the installer said the scratches shouldn't be an issue at all for electrical output or for the long term durability of the system. However, our own research suggests otherwise. Fortunately, we've raised this to our solar company's attention, and they've been apologetic and (thankfully) willing to make it right.

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.

Are solar panels defective?

While modern manufacturing processes are constantly improving, solar panels can still develop defects during production. These common solar panel defects can impact performance, longevity, and safety. The first group of defective solar panels is related to cell issues that are easy to notice even before installation.

What causes a solar panel to fail?

Hail is another major cause of stress for solar owners. Large hailstones can crack the glass and damage the underlying cells. It causes solar damage, significantly reducing efficiency and performance. Debris is another common reason for a cracked solar panel.
