Solar Battery Installation in Southern California

Under NEM 3.0, exporting solar to the grid pays a lot less than it used to. Batteries let you use your own solar in the evening instead of buying expensive peak-rate power back from the grid.

They also cover you during outages. Public safety power shutoffs, storms and grid events are a real thing – a battery keeps essentials running.

Time-of-use rate structures make the math even more favorable for storage – the priciest hours line up almost exactly with the evening window when solar production has already tapered off. A battery lets you shift the power you generated at noon into the 4–9pm rate spike instead of paying peak pricing for it.

We add batteries to systems we didn't originally install all the time. In most cases we can integrate storage without replacing your existing panels or inverter, depending on what you already have.

There's no universal battery size that fits every home. We look at your evening and overnight load – appliances, HVAC, any EV charging – against what your solar array actually produces in the shoulder seasons when days are shorter, and size around that instead of the sunniest day in July.

Homes that want whole-home backup during an outage need a bigger system than homes that just want the fridge, internet and a few circuits covered. We lay out both options with real numbers so you're choosing based on cost and need, not guesswork.
