Commercial Solar in Longmont: Value-of-Solar Math

For Longmont businesses, the value-of-solar credit rewards systems that are consumed on site. Manufacturers, food producers and offices with steady daytime loads can use most of what a roof produces; buildings with light daytime use export more and earn less per kWh.

01

Who’s a strong candidate

Longmont has a real base of manufacturing, food and beverage production and tech offices. Those operations tend to run through the solar day. We model hourly load against production so the design doesn’t lean on exports that LPC credits below retail.

02

Deadlines and depreciation

Commercial solar must generally be placed in service by December 31, 2027 to claim §48E unless construction started by July 4, 2026; consult a tax advisor, because a key IRS safe-harbor notice was vacated in court in June 2026. 100% bonus depreciation is available for qualifying property placed in service after January 19, 2025.

FAQ

Questions we hear

Does value-of-solar apply to commercial systems in Longmont?

LPC’s change applies to new or expanded systems after January 1, 2025. Confirm the treatment of your rate class with LPC; we check it for every proposal.

Should a Longmont business add storage?

If demand charges are a large share of your bill, or exports are credited well below retail, storage can improve the payback. Commercial storage keeps federal credit eligibility much longer than solar.

Who handles permits for a commercial project outside city limits?

If LPC serves the site, interconnection goes to LPC field engineering; the building permit comes from the county. We coordinate both.
