6 FAQs about [Scratches on the bottom 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.
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 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.
What causes micro cracks in solar panels?
Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module. The length of micro-cracks can vary; some span the whole cell, whereas others appear in only small sections of a cell. Micro Cracks in Solar Panel How do micro-cracks occur?
What causes scratches on thin glass covers?
On average, small and large scratches on the thin glass covers of solar panels are found in more than 70% of independent 3rd party quality inspections, such as those performed by Sinovoltaics Consultancy Services. Improper handling of the module at the factory or negligent and unsafe packing are common causes of these scratches.
