Here are 11 of the most common solar panel defects to watch out for in a solar installation, and how WINAICO works to prevent them from happening to your sites.
If these defective panels are put into use, they may reduce the efficiency of power generation and the life of the product, or even cause serious safety accidents. In order to avoid such accidents, it is a top priority to carry out relevant quality inspection before the solar panels leave the factory.
However, defects often are not the cause of power loss in the PV plants: they affect PV modules, for example, in terms of appearance (Quater et al.,2014). There are various diagnostic tools and methods to identify defects and failures on PV devices (Golnas, 2013), (Ndiaye et al., 2013) as discussed below. Visual Assessment.
Solar panels are generally very reliable and trouble-free as they have no moving parts and require minimal maintenance other than cleaning. However, like any manufactured product, solar panels can fail or underperform due to faulty materials or poor workmanship during the manufacturing process.
Most Common Solar Panel Problems include efficiency, maintenance, discoloration, degradation, cost, wiring concerns and hot spots.

6 FAQs about [Photovoltaic panels are defective when leaving the factory]
What are failures & defects in PV systems?
Failures & Defects in PV Systems: Typical Methods for Detecting Defects and Failures Generally,any effect on the PV module or device which decreases the performance of the plant, or even influences the module characteristics, is considered a failure. A defect is an unexpected or unusual happening which was not observed on the PV plant before.
Do solar panels have a manufacturing defect?
Fortunately, this is very rare, and usually, only 1 in 5,000 panels will suffer from a manufacturing defect. Defects are often associated with the constant drive to reduce costs, and not surprisingly, this is why lower-cost panels generally suffer more faults compared to panels from well-established premium solar brands.
Is it normal for solar photovoltaic (PV) cells to deteriorate over time?
In addition to the small number of manufacturing defects, it is normal for solar photovoltaic (PV) cells to experience a small amount of degradation over time.
Can a defect cause power loss in a PV plant?
A defect is an unexpected or unusual happening which was not observed on the PV plant before. However, defects often are not the cause of power loss in the PV plants: they affect PV modules, for example, in terms of appearance (Quater et al.,2014).
How to detect a defect in solar panels?
In order to avoid such accidents, it is a top priority to carry out relevant quality inspection before the solar panels leave the factory. For the defect detection of solar panels, the main traditional methods are divided into artificial physical method and machine vision method.
What are common solar panel problems?
In conclusion, being aware of common solar panel problems such as dust accumulation, shading, and microcracks can help system owners take timely action. Regular maintenance, professional inspections, and addressing potential defects will maximize solar panel efficiency. For more informative solar content, keep reading our blogs.
