A solar module quality check during production comprises of various components, including a detailed assessment of workmanship, documentation, and field tests and measurements – but the solar PV inspection checklist can vary depending on case by case. 1. Assessing the Workmanship of the PV Panels
This inspection covers visual inspection, quantity verification, field testing and measurements, and certification checks such as IEC, UL, and CE marking. These inspections can be performed at various stages, including: Apart from our quality control inspections for solar PV, we provide a variety of vendor assessment services.
The growth of photovoltaic power plants in both size and number has spurred the development of new approaches in inspection techniques. The most commonly employed methods include visual inspections, current-voltage measurements, infrared thermography, and luminescence imaging.
Thermography inspections excel at detecting various faults within the PV module, including mismatched cells, shaded cells, resistive solder bonds, localized shunting in cells, defective bypass diodes, or degradation of packaging materials (Schirripa Spagnolo et al., 2012).
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:
Estimation of the terminal voltage of a solar cell within a module (Köntges et al., 2009; Potthoff et al., 2010): Since solar cells are encapsulated in the solar module, performing an electrical measurement to determine their voltage becomes impossible.
