6 FAQs about [Photovoltaic panel blue spots]

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.

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.

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 is a hot spot in a PV module?

In a photovoltaic (PV) module, a hot spot describes an over proportional heating of a single solar cell or a cell part compared to the surrounding cells. It is a typical degradation mode in PV modules. Hot spots can origin, if one solar cell, or just a part of it, produces less carrier compared to the other cells connected in series.

What are the most common solar panel defects?

Common solar panel defects include microcracks, where small fractures in the cells can develop during manufacturing or transportation, potentially reducing efficiency. Delamination, the separation of layers within the panel, may lead to moisture ingress and performance degradation.

What causes PV module discoloration?

PV module discoloration can be caused by various factors, including: Exposure to UV Radiation: Over time, prolonged exposure to sunlight can cause degradation of the materials used in solar panels, leading to discoloration. This degradation can affect the appearance of the panels and reduce their efficiency.
