At Stony Brook University, researchers have quietly crossed a threshold that the solar industry has long sought: the ability to see failure before it arrives. By teaching a machine-learning algorithm to read the subtle language of inverter output and weather patterns, they have built a system that can identify physical defects in solar arrays weeks or even years before conventional methods would catch them. In an industry where equipment failures cost U.S. facilities an average of $5,720 per megawatt in 2024 alone, the shift from reactive repair to predictive care carries consequences that ext
