When a PV system changes ownership, a solar inspection helps uncover any issues so that the buyer knows the true value of what they’re purchasing. In addition, most solar equipment has a warranty period. A successful solar inspection can help you locate warrantable issues and give you documentable proof to make your warranty claim.
A solar PV module sample will be considered to be rejected due to its observable quality defects if any one of the following conditions are met: If any single observed defect has been evaluated as a Severity of 5. A Severity of 5 indicates a major quality issue; a critical failure or a fraudulent module.
Photovoltaic inspection methods
Visual inspection of a solar system is the simplest method of finding defective PV modules. It basically consists of walking through the rows of modules and determining if there are any visible defects. Unfortunately, this method cannot detect many types of defects, so it does not provide a sufficient inspection.
