Roof first. Solar second. One coordinated plan.
Most solar companies bolt panels onto a roof they never inspected. We start with the roof — because a system is only as good as what it's mounted to. Through our McKay Roofing partnership, you get one team that owns both layers of the job, and one warranty umbrella you can actually call.
- Roof condition assessed before designNo panels on a roof that won't outlast them.
- Single point of accountabilityNo finger-pointing between roofer and installer when something leaks.
- Storage-ready design from day oneEven if you add the battery later, the system's already wired for it.
From first quote to first sunrise on the meter.

Design meets your bill, not our sales quota.
Every system engineered for battery expansion.
What San Diego homeowners are saying.
"Nuon walked us through every rebate and made the roof + solar bundle a no-brainer. Crew was professional, install was clean, and the system's producing above estimate."
"Got four quotes — Nuon was the only one that actually inspected the roof first. Fair price, no upsell games, and the Powerwall has saved us during two outages already."
"From consult to power-on took about six weeks. They handled permits, HOA paperwork and utility interconnection. Best contractor experience I've had in ten years of owning this home."
Turn your rooftop into a P&L line item.
Warehouses, offices, retail centers, multi-family and agricultural operations across Southern California trust Nuon to design commercial solar and battery systems that offset demand charges, hedge against decades of utility rate hikes and qualify for federal ITC and depreciation benefits.
