Do I need utility permission in Colorado?

It depends on your state's rules and your utility. The safe path in Colorado is to use a UL-listed (UL 3700) microinverter and check your utility's interconnection policy (major utilities here include Xcel Energy) before you install; see the status for Colorado above for specifics.

Colorado now has a plug-in solar law. HB26-1007, signed by Gov. Jared Polis on May 7, 2026, takes effect January 1, 2027 and creates a formal legal category for “portable-scale solar generation devices.” It sets the highest plug-in cap in the U.S. — 1,920W of panel capacity — and requires utilities to accept meter-collar adapters. Colorado is solar-friendly with good sun; still confirm the setup and any interconnection steps with Xcel Energy or your co-op before you buy.

Before you buy in Colorado

Call your electric utility and ask: (1) do they allow small plug-in / behind-the-meter grid-tied solar, and (2) is any notification or interconnection form required? Stay within the wattage they specify, use a UL-listed microinverter, and keep written confirmation.

Then estimate your numbers with our savings calculator (pre-loaded with Colorado's rate).
