6 FAQs about [Photovoltaic panels can pass EL test]

Should El imaging be performed in-situ at PV power plants?

Thus, conducting EL imaging in-situ at the PV power plants is a good measure. As proposed by the EU Horizon 2020-funded SolarBankability studies and Solar Power Europe conducting IEC62446 and additional tests, like that of site EL imaging are a best practice.

Why is El imaging important for PV power plants?

Having the EL images allows the site owner to have a baseline from which to work. Particularly, given that microcracks may also occur during the handling, installation, and operation of the solar asset. Thus, conducting EL imaging in-situ at the PV power plants is a good measure.

How does an electroluminescence camera detect damage in a PV module?

The cells are like resistors (similar to an LED) and start to glow, causing the cells to become visible to an adjacent infrared camera. Wherever the individual cells do not glow, there is a defect. As shown in the following figure, the electroluminescence camera locates damage in a PV module which is invisible to the human eye:

How does a hot-spot test affect a photovoltaic module?

The hot-spot test motivated manufacturers to use bypass diodes, which protect the modules when the photocurrent generated by each cell shows variations because of partial shading or cell damage. These three changes helped to avoid important design flaws, thus dramatically decreasing failure rates.

Does sinovoltaics have El image criteria?

Sinovoltaics has in-house up-to-date EL image criteria that can be shared on request. Allowing the template for discussions on procuring quality modules and a comparison to the manufacturer’s internal quality criteria.

What is an electroluminescence solar module tester?

The electroluminescence solar module tester is a key tool for manufacturers to check and improve solar panel performance. If you are interested in solar energy or work in the solar industry, this guide will help you learn more about the machine used in making solar panels.
