Common solar panel defects.
Microcracks low cost solar cells can have structural defects which are not visually detectable.
Hotspots on panels are mainly caused by badly soldered connections or are a result of a structural defect in the solar cells.
If moisture finds its way into the panel it can cause internal corrosion.
Hot spots are places on the panels which are overloaded and therefore become warm.
It is therefore crucial to detect as soon as possible these problems.
The illustrations from the report below show the 5 different categories of backsheet defects and their frequency.
Broken and chipped solar cells are common and can indicate different issues.
