6 FAQs about [Photovoltaic panel el visual inspection equipment]
Why is El inspection important for solar PV project development?
Indeed, today, everyone involved in PV project development is aware of the EL inspection as a non-invasive and hands-on methodology for the detection of electrical-based defects in solar PV modules .
What is El inspection?
EL inspection applied to research and development of new photovoltaic devices. All you need for PV module testing devices.
Can El & visual inspections help prevent module damage?
However, the combination of EL and visual inspections can provide more detail about the origins of module damage. Clean Energy Associates (CEA) was recently engaged by an asset owner during the acquisition phase to perform due diligence by conducting visual inspections and EL testing for a 7MW solar project in the US.
What is the difference between visual inspection and El image testing?
Whereas the visual inspection only indicated 3.1% anomalies/defects, the EL image testing revealed that 17.5% of the modules tested contained microcracks, 23.8% contained impact points, and 1.6% contained backsheet scratches. Microcracks are a type of defect that cannot be detected with visual inspection alone.
Why do solar panels need El testing?
Electroluminescence (EL) Testing identifies microcracks in your modules and can help in identifying the root cause. Microcracks are present in most solar installations, but catching severe microcracks and removing them early can prevent considerable performance issues and investment losses.
What did the El inspection of the 315 modules reveal?
The EL inspection of the 315 randomly selected modules, however, told a different story. Whereas the visual inspection only indicated 3.1% anomalies/defects, the EL image testing revealed that 17.5% of the modules tested contained microcracks, 23.8% contained impact points, and 1.6% contained backsheet scratches.
