Own it and you fix the price.

A properly sized solar and battery system puts your cost around 18–24¢ per kilowatt-hour and holds it for 25 years.3 The utility keeps filing for increases either way.

Three reasons people move now.

Peak pricing is the real cost
SDG&E charges up to 69.6¢/kWh between 4 and 9 PM in summer.² A battery moves your house off the grid during exactly those hours.
The grid goes down; you don't
Storage keeps your refrigeration, lights, and network running through an outage. Solar alone will not.
It is an asset, not an expense
Owned systems carry a measurable resale premium — roughly $15,000 on a typical home in the Berkeley Lab dataset.⁴ Leased systems generally do not.

What we take on.

C-10 licensed, CSLB #1088165. Any electrical work the install depends on is handled in the same scope.

New solar & battery
Custom-sized systems, designed around your actual usage rather than a package.
Battery add-ons
Storage retrofitted to existing solar, including arrays we didn't install.
Service & repair
Diagnostics, inverter faults, and monitoring on any manufacturer.
