Commercial Solar in Arapahoe County, CO

Arapahoe County’s commercial stock ranges from office towers around the Denver Tech Center to light industrial buildings in Aurora and Englewood and agricultural operations on the plains. Utility territory — Xcel in the west, CORE in the east — and whether a property is incorporated determine both the economics and the permit path.

Business solar while the federal credit is still on the table.
01

Office and light industrial on Xcel

Office buildings have daytime loads that line up well with solar, but their bills are often driven by demand charges from afternoon HVAC. Light industrial buildings with big, flat roofs can host large arrays; the question is whether the load is big enough to use what the roof can produce.

We model energy and demand savings separately, and we’ll tell you if storage — not more panels — is the lever that moves your bill.

02

CORE commercial and agricultural accounts

CORE net-meters commercial systems up to 25 kW. Larger systems are interconnected as qualifying facilities under CORE’s tiered process, and how their exports are credited should be confirmed with CORE in writing before sizing. For farms and shops, sizing to on-site use usually beats oversizing.

03

Contractor requirements and federal timing

Unincorporated Arapahoe County requires NABCEP certification and a county license for solar contractors, and engineered structural review for arrays. As of September 2026, commercial solar generally must be placed in service by December 31, 2027 to claim §48E unless construction began by July 4, 2026; storage has a longer runway. Ask your CPA how 100% bonus depreciation applies.

FAQ

Questions we hear

Does solar make sense for an office building near the Tech Center?

Often, because office loads peak during daylight. Demand charges can limit savings, so we model solar with and without storage.

What’s CORE’s net-metering limit for businesses?

25 kW. Larger commercial systems follow CORE’s qualifying-facility interconnection process, so confirm export credits with CORE before sizing.

What licenses does a solar contractor need in unincorporated Arapahoe County?

NABCEP certification and an Arapahoe County contractor license, plus state electrical licensing for the electrical work.

Is the commercial federal credit still available?

As of September 2026, yes, for solar placed in service by the end of 2027 or begun by July 4, 2026. Confirm with your tax advisor.
