6 FAQs about [What s the matter with white spots on photovoltaic panels]

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.

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.

Can discoloration damage a solar panel?

In some cases, severe discoloration could potentially indicate damage, although the presence of discoloration does not necessarily imply a solar panel defect. The most common defects in solar panels include issues such as hot spots, snail trails, and imperfections in the materials.

Why should solar power professionals know about common solar panel problems?

Thus, solar power professionals need to be knowledgeable about common solar panel problems to better service solar clients and prevent underperforming solar assets. Regular maintenance and performance modeling can help prevent revenue loss for solar system owners through early detection and corrective action.

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 solar panels crack?

This led to extremely brittle solar cells prone to crack from any forceful impact. When microcracks form in a solar panel, the affected solar cells will have trouble conducting electric currents, which lead to poor energy production and hot spots. EL picture of microcracks on solar panels due to poor handling practices.
