Lawrence Pratt is the CSIR’s primary solar expert and leads the application of electroluminescence technology for PV quality assurance. Solar panels and pixels aren’t often imagined in the same sequence of thought, but using the latter to evaluate the former can yield huge savings. That's because by reducing the technical risks of installing substandard panels, the financial risk is also reduced.
CSIR researchers go deeper. Using digital cameras with their high band-pass filters installed, Pratt’s team capture electroluminescence images. These image files can reveal even the tiniest microfractures within a solar panel’s structure, which might only be one or two pixels wide. Bringing electroluminescence imagery and testing software based on AI to the market enables the CSIR to empower solar customers and project engineers. The more panels are screened, the better the software becomes at recognising issues.
