The guide is designed for the visual inspection of front-contact poly-crystalline and monocrystalline silicon solar PV modules, helping the inspector detect major defects. The guide should supplement international testing standards, but not replace them, the Sinclairs write (in the guide).
ks and potential-induced degradation (PID) in the module, which afect the overall performance of the module. The IR ther ographic inspection of PV modules is performed to detect non-conformities such as hotspot and diode failure. During thermo-graphic inspection the evalu
The inspection generally include factors such as: Visual Inspection: Visual inspection of solar panels include checking for visible defects, such as cracks, discolouration, scratches, or dents on the solar module, as well as any abnormalities in the framing or glass, junction box, and wiring.
One effective method is to conduct a during-production inspection. This quality check thoroughly inspects each panel’s materials, manufacturing process, and performance characteristics to ensure they meet the required standards. Ensuring the quality of solar panels during production inspection is important for multiple reasons:
In a single inspection step, CELL-Q checks every solar cell's print quality and anti-reflection coating. Any print and color defects on all cell technologies are reliably detected.
The schematics in the Terminology section describe where each component is found on a common solar PV module. A Severity Rating is also defined to give users guidelines on how concerning a particular defect may be.
