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.
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.
With prolonged exposure to sunlight, the EVA starts to oxidize and causes the surface to change color. Dirt, dust, bird droppings, and other environmental factors can also cause solar panel discoloration. Furthermore, pollution has been linked to causing a greyish hue on 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.
Solar panel defects are very rare, but they still might happen. Learn about the most common defects panels have, and where they come from.
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 you add solar panels to an existing installation?
For this reason, any panels you plan to add should have the same power rating as the original panels. Again, this issue is avoided by getting micro-inverters, as the solar panels work independently from one another. Roof. Solar panels weigh between 15 and 30kgs, so you''ll need to make sure that your roof can support the added weight and space.
Panels with small strange spots
Those spots are most likely inherent to the automated manufacturing process used to mass produce multicrystalline cells. I buy and sell solar panels and have noticed these markings on many panels from many different mfg. They (the markings) are all located on the same area of every cell in many A grade modules I have seen.
