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).
