SCE, heat & permits
What shapes solar design in San Bernardino County
The cities we serve across the county are SCE territory under NEM 3.0 — and Inland Empire summers make battery-backed designs the default, not the upgrade.
SCE — NEM 3.0 Net Billing
Ontario, Rancho Cucamonga, Fontana, San Bernardino, Chino, and Chino Hills are Southern California Edison territory under the CPUC's NEM 3.0 Net Billing Tariff — where pairing solar with a battery to cover the 4–9 PM peak is what makes the math work.
Inland heat & summer peaks
The Inland Empire runs hotter than coastal Southern California, so cooling loads — and summer bills — climb fast. We size systems to your real usage pattern, with storage dispatching through the expensive evening window when air conditioning runs hardest.
Permitting by city AHJ
There is no single county permit: each incorporated city reviews solar through its own building department, and unincorporated communities go through the County of San Bernardino. We prepare, submit, and track every permit through your specific AHJ.

Proof you can see
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. Each dot is one real record (a couple dozen without a mappable location count toward the total but aren't shown); positions are approximated to the neighborhood to protect customer privacy.
Built for inland heat
Long cooling seasons meet the 4–9 PM peak
Inland Empire summers mean months of hard-running air conditioning — and on SCE time-of-use rates, the heaviest usage lands in the 4–9 PM peak window, the most expensive hours of the day, right as solar production falls off. That's why we design battery-first here: the panels generate through the long, sunny days, the battery covers the evening peak, and your home stays powered through outages. Every permit runs through your city's own building department, and we handle it — plan-check to final inspection to SCE Permission to Operate.

- Battery dispatch tuned to SCE's time-of-use peak pricing
- Each city's own building department managed for incorporated cities
