6 FAQs about [What else can be checked for photovoltaic panels besides EL]

Why do solar panels need El testing?

EL testing acts as a preventive measure by identifying these issues early in the manufacturing process, allowing manufacturers to address them before the modules reach the end-users. Solar panel manufacturers leverage electroluminescence testing to enhance the reliability of their products.

What defects are common when testing solar panels?

The following defects are common when testing solar panels: Lower output than stated in data sheet (we require positive tolerance on each solar panel) Other defects that we find are dirt marks on the pv module, gaps on the corner of the pv frame, poor quality labels and solar panels that do not meet the requirement of positive tolerance.

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 .

Do PV panels need to be monitored online?

Thus, a proper monitoring of the PV panels is required. The current state of the art is that, despite lot of algorithms and hardware which were developed so far, online monitoring of PV systems is still in the prototyping stage and yield only limited fault information before a mature and standardized metrology can take place.

Why do solar panels need electroluminescence testing?

Solar panel manufacturers leverage electroluminescence testing to enhance the reliability of their products. By thoroughly examining each module for defects, manufacturers can provide customers with solar panels that are not only efficient but also durable.

Do solar panels need a visual inspection?

During the visual inspection each solar panel is reviewed by an independent certified testing agency for defectives, including scratches, glue marks, montage frame and anything that is deviant. Most manufacturers use what is called the I-V (Current-Voltage) data measurement test, sun simulation test or most commonly: flash test.
