Commercial Solar in Denver County, CO

For Denver commercial and multifamily owners, solar is increasingly a compliance question as well as a savings question. Energize Denver building-performance rules apply to buildings of 5,000 square feet and larger, with updated rules adopted in August 2026. Commercial systems don’t qualify for SolarAPP+ and go through standard plan review.

01

Energize Denver and on-site solar

The city divides covered buildings into small (5,000–24,999 sq ft) and large (25,000 sq ft and up). Its rules and technical guidance set each building’s targets and deadlines. How on-site solar is credited toward a target is defined in those documents, so read your building’s requirements — or have your energy consultant do so — before sizing an array for compliance.

We design to the numbers you need to hit, and we coordinate with the consultant who handles your benchmarking.

02

Xcel commercial bills: energy vs. demand

Most commercial Xcel rates charge separately for energy and for peak demand. Solar cuts energy costs predictably; cutting demand charges usually takes a battery programmed to shave peaks. For restaurants, breweries and small manufacturers with sharp afternoon peaks, the storage piece often matters more than the panel count.

03

Tax treatment for 2026–2027 projects

Businesses can still claim the federal §48E credit for solar placed in service by December 31, 2027 (or later if construction began by July 4, 2026), and storage keeps eligibility much longer. 100% bonus depreciation has been restored for qualifying property. Confirm with your CPA — these rules have shifted repeatedly and court rulings are still pending.

FAQ

Questions we hear

Does Energize Denver apply to my building?

It covers commercial and multifamily buildings of 5,000 square feet and larger. Check the city’s current rules for your building’s category and deadlines.

Can rooftop solar help meet Energize Denver targets?

On-site solar can play a role; how it is counted is set by the city’s rules and technical guidance. Confirm the method for your building before sizing a system.

Can a commercial project in Denver use SolarAPP+?

No. Denver’s SolarAPP+ process covers single-family and duplex rooftop systems; commercial projects go through standard plan review.

Will solar cut the demand charges on my Xcel bill?

Not reliably by itself. Pairing solar with a battery that targets your peak is usually what moves demand charges.

Is there still a federal credit for commercial solar in Denver?

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