There are white spots on the photovoltaic grid line

If you see dark or brownish lines spreading across the panel surface, you have a case of snail trails. In most cases, this defect is a result of a combination of factors, including micro cracks. Moisture seepage into the panel material from a crack can lead to a chemical breakdown of the EVA (Ethyl Vinyl Acetate) material.

Potential induced degradation, hot spot, white spot, cell finger metallization, humidity corrosion, cracks, micro-cracks, soldering, discoloration, snail trails and other defects and failures can be detected by these assessment techniques (Ebner et al., 2013), (Potthoff et al., 2010).

Snail trails or worm marks are short thin dark lines on the surface of a solar panel. Just to clear it up: they have nothing to do with actual snails. They may appear several years after the installation along the edges and, most importantly, where microcracks are located.

As some brands cut corners on product quality to remain price-competitive, solar panels start to fail in the field before their expected lifetime is up. Here are 11 of the most common solar panel defects to watch out for in a solar installation, and how WINAICO works to prevent them from happening to your sites.

Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.

6 FAQs about [There are white spots on the photovoltaic grid line]

What causes hot spots on solar panels?

Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.

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.

How to detect hot spots in solar panels?

You can detect an emerging hot spot with an infrared camera only. Eventually, hot spots in solar panels become visible to the eye: the problematic cell becomes brownish. Hot spots lead to a faster solar panel degradation and can even start a fire on your roof. To avoid that, clean your panels from dirt every now and then.

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.

What happens if a solar panel is discolored?

This discoloration can impact the panel’s performance, leading to decreased efficiency and reduced power output. Solutions to solar panel discoloration include regular professional cleaning, proper installation, monitoring system performance, and contacting the installer for assessment and guidance.

How do I know if my solar panels are defective?

This issue can be detected using an infrared (IR) camera, which shows a noticeable temperature difference between the solar cell strings. To avoid this problem, using more advanced manufacturing techniques and conducting careful EL inspections before shipping can prevent such defects in solar panels. 22. Defective Junction Box
