The study performed two related analyses using data from a new-construction residential community equipped with rooftop solar and storage (S+S) in Arizona. Analysis of customer bill savings: The study analyzed the factors that determine customer electricity cost savings from S+S adoption. Analysis of system performance: The research compared the Arizona case study data to modeled system performance to understand how models deviate from real-world outcomes. Based on these findings, NREL explored ways to improve such models and, conversely, use modeled results to suggest improvements to S+S dispatches.
