SDG&E territory
What shapes solar design in San Diego County
San Diego County runs on SDG&E — where unusually high rates make solar payback strong, and NEM 3.0 makes the battery the centerpiece of the design.
SDG&E — steep rates, strong payback
San Diego Gas & Electric's residential rates are among the highest of any major U.S. utility. Every solar kilowatt-hour offsets an unusually expensive grid one — which is why SDG&E territory has some of the strongest solar economics in California.
NEM 3.0 — battery-first design
SDG&E is CPUC-regulated, so the NEM 3.0 Net Billing Tariff applies: exports earn little, and the savings come from storing daytime solar for the expensive evening hours. We design solar-plus-battery as the default and model your actual rate plan.
Permitting by city AHJ
Each city — San Diego, Chula Vista, Escondido, Carlsbad — reviews solar through its own building department, and unincorporated communities go through the County of San Diego. 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.
The SDG&E math
High rates are the problem — and the reason solar works
San Diego's mild coastal climate keeps cooling loads modest, but SDG&E's per-kilowatt-hour prices do the damage on their own — among the highest of any major utility in the country. That flips the solar equation in your favor: every kilowatt-hour from your roof replaces one of the most expensive grid kilowatt-hours in America. Under NEM 3.0 we pair panels with a battery so daytime production covers the pricey evening hours, and we handle your city's permitting and SDG&E interconnection end-to-end through Permission to Operate.
- Designs modeled against your actual SDG&E rate plan
- Battery dispatch tuned to evening peak pricing under NEM 3.0
- Each city's own building department managed for incorporated cities
- One in-house team across design, permits, install, and inspection
