Example: a Platt Park bungalow
A 1920s bungalow in Denver’s Platt Park with 14 panels on microinverters, its installer long out of business. Output watch starts in March. In May, one panel reads near zero on four clear days while its neighbors hold steady. The monitoring desk emails the owner panel-level screenshots and the dates, and suggests a licensed electrician, since one dark microinverter is an electrical question, not a cleaning one.
