A Slightly Different Question

Five Years Measuring a Home Solar App's Daily Self-Sufficiency Score Against an Independently Metered Grid Draw

A School of Continuous Improvement Impact Report pairs five years of a home solar app's daily self-sufficiency score against an independently calibrated meter at 1,240 households' grid connection points, finding the two track closely on an ordinary day and diverge most in the week daylight saving begins, and that households check the score most often at exactly the hours it is least settled.
