Legal Status: Can You Plug In Solar in Colorado?

Current Disposition: Balcony solar legal

Colorado HB26-1007 was signed into law on May 7, 2026, and its general provisions take effect August 12, 2026 unless a referendum petition was filed. It adds C.R.S. 40-2-140 for portable-scale solar generation devices: a single photovoltaic system per address that supplies no more than 1,920 watts to the grid and is labeled and listed by a nationally recognized testing laboratory. A customer may connect no more than one device to a single wall outlet per address. Electric providers may not require prior approval, a fee, or equipment beyond what the device's UL listing integrates, but may require notice of the device's presence and size in kilowatts. Devices of 391 watts or less are also exempt from the solar photovoltaic installation requirements of C.R.S. 40-2-128 and from building safety code or product listing provisions that would require rewiring. From January 1, 2027, no person may unreasonably prohibit a device, and covenants that do are void; property owners may still set reasonable restrictions.

Statutory Capacity Limit

Authorized power: 1920W (Maximum output to the grid; a single labeled and listed system per address, one device per wall outlet. Devices of 391 W or less are also exempt from C.R.S. 40-2-128 installation requirements and from code or product listing provisions that would require rewiring). No provider approval, fee or equipment beyond the device's UL listing; provider may require notice of presence and size in kilowatts

Colorado HB26-1007 - official bill page

Colorado HB26-1007 (C.R.S. § 40-2-140) bars provider fees and eliminates separate production meters where net energy consumption can be measured at the customer billing meter.

Consumer Action: Check with Xcel Energy or your electric cooperative to verify your billing meter handles bidirectional flow. Colorado statute specifically finds that separate production meters add unnecessary cost, and prohibits electric providers from charging fees or requiring extra controls beyond the product listing.

Statutory Export Rule: “requiring separate production meters for customer-sited distributed energy resources in circumstances where net energy consumption can be accurately measured at the customer's billing meter adds unnecessary cost and complexity that discourage beneficial distributed energy resources.”

Utility Fee Prohibition: “A PROVIDER OF RETAIL ELECTRIC SERVICE OR WHOLESALE ENERGY SHALL NOT REQUIRE A CUSTOMER TO: ... (II) PAY THE PROVIDER A FEE RELATED TO A PORTABLE-SCALE SOLAR GENERATION DEVICE; OR (III) INSTALL ANY ADDITIONAL CONTROLS OR EQUIPMENT BEYOND WHAT IS INTEGRATED INTO A PORTABLE-SCALE SOLAR GENERATION DEVICE PURSUANT TO THE UL LISTING OF THE DEVICE.”

Incentives, Solar Rights & Grid Barriers

State Incentives & Solar Rights

No provider approval or fee, and no equipment beyond what the device's UL listing integrates, for devices up to 1,920 W
Devices of 391 W or less are exempt from the solar photovoltaic installation requirements of C.R.S. 40-2-128 and from building safety code or product listing provisions that would require rewiring
From January 1, 2027, unreasonable prohibitions of qualifying devices are void
By December 31, 2026, the PUC must revise its rules to require qualifying retail utilities to post a list of at least one approved meter collar adapter and to decide on customer-owned adapters within 90 days
Existing state rebates and tax incentives for full rooftop solar
