6 FAQs about [Blurred spots appear on the back of the photovoltaic panel]

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 do you know if a solar panel is overheating?

It may either appear as noticeable damage on the surface or as a visible brown spot on the solar panel. A good way to detect them is through thermography. Thermography is a safe diagnostic tool that consists of a thermal camera to help identify overheating components and lines in the electric panels, cells, or modules.

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 left unchecked?

Portions of backsheet could show through and start a fire if left unchecked. To eliminate hot spots, reliable, skilled solar panel fitting companies like Aztech Solar check for imperfections on each solar cell before installing them. Broken cells and poorly soldered ribbons get automatically discarded. 2. Microcracks

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.

Are solar panel backsheet defects on the rise?

Here’s the bad news: according to the 2019 Global PV Reliability Report from DuPont, solar panel backsheet defects are on the rise. The good news is that Aztech Solar uses only PV panels with backsheet materials that have been tested for damp heat and thermal cycling reliability – ensuring maximum water insulation.
