Commercial Rooftop Solar in Southern California

Commercial roofs are some of the best solar real estate in California — large, unshaded, and directly connected to a high-consumption load. Nuon Energy engineers ballasted and mechanically-attached PV systems that offset daytime demand and hedge against decades of rate escalation.

The Nuon Standard for
commercial rooftop solar.

With high electricity rates and strong solar incentives, Southern California businesses are well positioned to see fast returns on commercial rooftop solar. Every system is custom-designed to fit your building, roof structure, and energy profile — providing reliable power while supporting long-term sustainability goals.

Systems are built with Tier-1 modules, string or central inverters sized to your service, and monitoring at the array, string and revenue-grade level so you can prove production for financing, PPAs, and depreciation.

Commercial Rooftop Solar FAQ

What size system do most commercial buildings need?

+
Most warehouses, retail and office buildings we serve land between 100 kW and 500 kW. Larger industrial sites and multi-building portfolios go into the multi-MW range. We size the array against your interval data, not just square footage.

PPA, lease or ownership — which is right for us?

+
Ownership delivers the strongest long-term return when you can use the ITC and MACRS depreciation. PPAs and leases work well for non-profits or businesses that prefer zero capex and a fixed $/kWh rate. We model all three side-by-side before recommending.

How long does a commercial install take?

+
Design, permitting and utility approval typically take 3–6 months; the actual roof install runs 4–10 weeks depending on size. PTO from your utility usually adds 2–6 weeks after mechanical completion.
