Flash of brilliance

Machine vision has become established in almost every stage of the photovoltaic production process, in spite of it being a comparatively new element of automation technology.rnHowever, it offers more than a simple inspection capability used to check the quality at the end of individual process steps. While this approach prevents faulty product reaching the end user, it does not eliminate waste, as 'out of spec' product has to be thrown away. Using the image-processing data to provide real-time feedback on the process and to link into the process control system can keep a process under control and minirnise waste.
