Powering homes across Southern California
Every dot is one real OC Solar project or service call — thousands of them, blanketing Orange County, Los Angeles, the Inland Empire, Ventura County, San Diego, and the desert. Hover any dot for the project type, area, and year — chances are we've already powered a home near you.
across SoCal and beyond
Per our company records as of June 2026 — every project and service call we've taken on, excluding cancellations.

Your home.

Make more of the power you make.
Explore solar and battery storage designed around your home and the way you use energy.

My electric bill keeps going up
Rates rise every year, the 4–9 PM peak is priced highest, and NEM 3.0 pays little for solar you send back to the grid.
Your home runs the expensive evening hours on power it made at noon, so the hours the utility prices highest are the hours you're not buying.
Solar sized to your real usage plus a battery for the peak — designed online, no sales appointment.
A backup plan. Built into your home.
Find the right battery setup for the things you want to keep running when the grid goes down.
Explore this option
We lose power in outages
PSPS shutoffs and grid failures never warn you, and grid-tied panels alone shut off with the grid.
The lights, fridge, Wi-Fi, and medical equipment stay on — automatically — while the block goes dark.
A Tesla Powerwall 3 or Enphase battery sized to your essential loads, installed by a Powerwall Premier Certified crew.
Your solar. Ready for what’s next.
Explore adding storage or panels, starting with the system and utility agreement you already have.
Explore this option
I have solar but the bill is still high
Under NEM 3.0, exported daytime solar earns a fraction of what the evening peak costs, so panels alone leave money on the table.
Your existing panels start paying again, because the surplus gets stored and spent when power is priced highest.
We check the inverter, utility agreement and roof, then add storage or panels only where it pencils.
Get your solar back on track.
Find local help for a system that stopped working, an unfinished installation, or an installer that disappeared.
Explore this option
My installer disappeared or the system stopped working
Production dropped, the monitoring went dark, and the company that installed it no longer answers — or no longer exists.
A system that works and is monitored again, serviced by a local company that has been here since 2016 and answers the phone.
Any-brand diagnostics with a written scope before any repair, including manufacturer-warranty claims on orphaned systems.
Plan the roof and solar together.
Explore roofing and solar options together before deciding what belongs on your home.
Explore this option
I need a new roof too
A worn roof under a 25-year array means tearing the panels off later, and two contractors on one roof means a leak nobody owns.
One permitted project, one crew, one warranty — the roof and the solar finished together and never fighting each other.
Owens Corning re-roof or Tesla Solar Roof, with the array planned into the roof design from day one.
Come home. Plug in.
Explore home charging that fits your electrical panel, your solar, and your daily routine.

I'm getting an EV
Charging on grid power at peak rates hands back much of what you saved on gas, and a wall outlet takes days.
A car that fills up overnight or on daytime solar, on power you already made.
A Level 2 charger wired for your panel and your solar under our own C-10 electrical license.
