What the law says

HB26-1007 was signed May 7, 2026 and has been in effect since August 12, 2026 (Colorado legislature). The act "defines, and creates requirements for, portable-scale solar generation devices" and treats them as a distinct device class.

The signed act limits a device to 1,920 W of output to the grid, one system per address and one device per outlet; it does not say AC or DC. It also "prohibits a provider of retail electric service or wholesale energy from ... requiring a customer to obtain the provider's approval before installing or using a portable-scale solar generation device."

From January 1, 2027, a covenant that unreasonably prohibits these devices is unenforceable, and the act clarifies portable-scale devices are treated as an energy-efficiency measure on and after January 1, 2027. It requires the commission to revise interconnection rules by December 31, 2026 and directs municipally owned utilities to maintain a public list and process for meter collar adapters.

  • Signed: May 7, 2026; in effect since August 12, 2026 (legislature).
  • Cap: 1,920 W, one system per address; AC or DC not stated (signed act).
  • Utilities may not require approval or a fee but may ask for the device’s size; interconnection rules due by December 31, 2026.
  • Landlord and HOA restrictions are limited; devices treated as energy-efficiency measures from January 1, 2027.

Before you buy in Colorado

Check three things before you buy: your utility's published process for meter collar adapters, whether a landlord or HOA imposes reasonable restrictions, and the product's safety certifications. The law prevents utilities from requiring prior approval but also requires installations to meet fire and building codes.

Look at the product label for listed standards and for any UL 3700 listing. For example, EcoFlow's 800 W kit (2 × 400 W panels; inverter output up to 1,200 W AC) lists UL 1741 but its UL 3700 status is not published; it was $1,099 on the official store, checked October 14, 2026 (sold out that day). EcoFlow's single-panel kit (400 W) was $799 on the official store, checked October 14, 2026.

Kits that fit the 1,920 W limit include the EcoFlow options above and the Mango Power S 1200W (1,200 W of panels; inverter output up to 1,200 W AC), which lists CA Rule 21 / IEEE 1547 compliance and was $2,698 on the official store, checked October 14, 2026. Use the kit list and the calculator to compare production at your address.

  • Ask your utility about meter collar adapter processes and any municipal public lists.
  • Confirm seller-stated certifications; UL 3700 listing is separate from seller-listed UL 1741.
  • A property owner may set reasonable restrictions but may not unreasonably prohibit a device; from January 1, 2027 a unit owners’ association may not prohibit one.

Questions

Do I need my utility's permission to install plug-in solar?

No. HB26-1007 "prohibits a provider of retail electric service or wholesale energy from ... requiring a customer to obtain the provider's approval" before installation. The commission must update interconnection rules by December 31, 2026.

Can my landlord or HOA stop me from using a plug-in kit?

From January 1, 2027, a covenant that unreasonably prohibits a device is unenforceable, though a property owner may set reasonable restrictions. It also clarifies such devices are treated as an energy-efficiency measure on and after January 1, 2027 for unit owners' associations.

How big a kit can I have in Colorado?

HB26-1007 sets a limit of 1,920 W of output to the grid, one system per address. The act does not say whether that limit refers to AC or DC output.

How much will an 800 W kit produce and save in Colorado?

The calculator gives for an 800 W kit at the state population center: 892 kWh a year (vertical, south), with 397 kWh used at home (46%) and 458 kWh exported; at the EIA average rate of 16.72 cents/kWh that home-used power is worth $66 a year ($664 over 10 years, no rate growth; exports paid 0). Tilting the kit to 30° increases production to 1,302 kWh and raises annual savings to $82.
