Analysis of module recycling using the AI techniques may consider one or more of the following: module model; module manufacturer; module type (e.g., c-Si versus CdTe); power rating; module history; module label information; predicted/actual market prices; others. An outcome of AI analysis can offer estimates of resultant effect(s) upon speed and efficiency, by which materials travel through the recycling system. One possible benefit is the ability to rapidly optimize system parameters, providing high solar module throughput in the recycling system over time.
