About Scratches on the photovoltaic panel surface
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.
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.
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. What may happen however is that the scratches may cause some very slight shading onto some cells, and even if only a couple of cells experience some shading the output loss may not be insignificant as cells are .
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.
The only sensible way to test which panels are underperforming would be to put either micro-inverter or optimisers on each panel. You may find that a panel with minor scratches performs worse than a panel with serious scratches. Solar Edge would be my choice if you were to go down this route.
Extended Lifespan: Accumulated dirt and debris can cause scratches, etching, and other forms of damage to the solar panel surface over time. Proper cleaning helps prevent such damage, extending the lifespan of your solar panel system.
As the photovoltaic (PV) industry continues to evolve, advancements in Scratches on the photovoltaic panel surface have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Scratches on the photovoltaic panel surface]
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.
How do I know if my solar panels are monocrystalline or polycrystalline?
The appearance of solar panels varies in color depending on if they are monocrystalline vs polycrystalline. Choose early morning or evening time to clean the panels. If you clean them during the blazing sunlight, the panels will dry quickly and smudges will appear on the surface.
How do I know if my solar panels are delaminated?
If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection. Micro cracks are tiny tears in solar cells stemming from haphazard shipping and installation or defects in manufacturing.
Why do I have dark spots on my solar panels?
Without a secure seal, moisture and air can enter the system, causing corrosion and substantially reducing panel performance. If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection.
