Stacking incentives, as of September 2026
The City of Boulder rebates roughly 15% of city sales and use tax on solar and battery materials and permits for Boulder businesses. Federally, §48E is available for commercial solar placed in service by December 31, 2027 (or begun by July 4, 2026), storage keeps eligibility through 2033, and 100% bonus depreciation is back. Talk to your CPA about how they combine.
Shutoffs have a business cost too
The December 2025 and March 2026 shutoffs de-energized customers across Boulder County, and a business on a de-energized line loses power like any home. For restaurants, labs and anyone with refrigeration or servers, commercial storage can keep critical loads running — and can shave demand charges the rest of the year.
FAQ
Questions we hear
Does Boulder’s tax rebate apply to commercial solar?
The city’s program covers Boulder residents and businesses. Apply within 12 months of final inspection; it’s subject to funding availability.
Can a leased commercial building in Boulder go solar?
Yes, with the owner’s agreement. A PPA or lease structure can work for tenants; roof rights and lease term are the first things to settle.
Is commercial storage worth it in Boulder?
When shutoff risk, demand charges and critical loads line up, often yes. Storage also keeps federal credit eligibility far longer than solar.
