In November 2011, Sunrun installed a solar energy system on the roof of my home in Westlake Village, California. The system was placed under a 20-year lease by a previous homeowner. When I purchased the property, the lease transferred to me — obligating me to purchase every kilowatt-hour the system generates at a rate that escalates 2.9% annually. In exchange, Sunrun owns, operates, maintains, and monitors the equipment for the life of the contract.
For the first several years, the system worked as described. Then, beginning in early 2024, it started shutting itself down. Not once. Not occasionally. Repeatedly — 237 times over two years, triggered by the same recurring ground fault condition. Each shutdown killed power production for the remainder of the day. Each event was logged by the inverter and transmitted to Sunrun's monitoring infrastructure. None of them generated an alert, a phone call, or a service visit.
I discovered the problem myself in February 2026 — not because Sunrun told me, but because I noticed my electricity bills climbing. When I investigated, I found not just the electrical fault, but a separate set of installation defects on the roof: abandoned penetrations, missing flashing, and code violations that have been exposed to the weather since the original installation in 2011.
This site documents what I found. Every data point presented here is derived from Sunrun's own monitoring systems, my utility records, and physical inspections of the equipment on my property. The production data comes from Sunrun's API. The fault events were detected from that same data. The photographs were taken by my own drone and camera.
