The project
A complete Tesla energy system for a San Diego home: a ~9.2 kW Tesla Solar Roof, two Tesla Powerwall 3 batteries totaling 27 kWh of storage, and a Tesla Backup Switch. Rather than panels mounted over an existing roof, the solar shingles are the roof itself — generation built directly into the roofline.
Installed in 2024 on SDG&E, the system charges the Powerwalls from daytime production and runs the home on stored energy through the evening peak, with the Tesla Backup Switch providing backup power when the grid goes down.
