In our final vlog, CEA’s Paul Wormser discusses how independent quality assurance and supply management can help prevent installing megawatts of defective modules

Video Transcript:

It's important to try to avoid having microcracks in the first place. And what that means is really good control over all of the different sources of microcracks along the line from the moment you slice a wafer, to the moment you install a module.

In terms of mitigating those risks, we would like to prioritize what's happening in the factory because that's where most of the microcracks are born.

And by having Clean Energy Associates in the factory, watching the process and making sure the process is running well, watching the offline testing and making sure the test results are pass, watching the electroluminescence imaging and the interpretation of those images to find out where the cracks might be, watching the repair process to make sure that you're actually doing a repair and not creating new damage, and watching the final product that comes off the line - all of these are areas where you invest in a quality assurance and quality oversight system to try to mitigate and minimize the presence of cracks to begin with.
