SCE, CPA & PSPS
What shapes solar design in Ventura County
Ventura County runs on SCE wires with Clean Power Alliance generation in most cities — and in fire-weather terrain, battery backup is as much about resilience as rates.
SCE delivery — NEM 3.0
Ventura County homes are in Southern California Edison territory, so the CPUC's NEM 3.0 Net Billing Tariff governs solar — exported power earns far less than it used to, which makes pairing solar with a battery for the 4–9 PM peak the design that pays.
Clean Power Alliance generation
Most Ventura County cities — including Ventura, Oxnard, Thousand Oaks, and Simi Valley — buy generation through Clean Power Alliance, the region's community choice aggregator, while SCE delivers the power and handles interconnection. Solar works the same; we design to your actual rate plan.
PSPS & fire-weather backup
High-wind fire weather brings Public Safety Power Shutoffs to hillside and canyon-adjacent parts of the county. A battery keeps refrigeration, Wi-Fi, and medical equipment running when lines are de-energized — backup value on top of the rate savings.

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.
Coast to valley
Marine layer at the beach, heat in the valleys
Ventura County spans two climates: coastal Ventura and Oxnard live with morning marine layer and mild cooling loads, while inland Thousand Oaks and Simi Valley run warmer summers with real air-conditioning seasons. Those are different production curves and different usage patterns — so we design from your actual roof and bills, not a county-wide template. Permits run through each city's own building department — or the County of Ventura for unincorporated communities — and we prepare, submit, and track every one until your system is switched on.
- Production modeled to your microclimate — marine layer or valley heat
- Each city's own building department managed for incorporated cities
- SCE interconnection through to PTO, CPA accounts included
- One in-house team across design, permits, install, and inspection
