What the primary source says
Colorado is one of the clearest enacted state markets for plug-in solar. The law defines qualifying portable-scale solar and says a utility may not require prior approval for a compliant device. It also makes unreasonable restrictions void and addresses common-interest communities beginning January 1, 2027. Verify the exact statutory definition, output limits and current code requirements before buying.
Utility permission is not the only check
A state interconnection rule is not a substitute for secure mounting or permission to modify rented or shared property. Review leases, association rules and local safety requirements separately.
What to verify before buying
- Open the official source below and confirm the current status and effective date.
- Ask the serving electric utility for its current process for the exact product and address.
- Match the complete system to required certification and outage-isolation language.
- Confirm electrical, mounting, landlord and association requirements.
- Estimate savings and payback using your electricity rate and realistic onsite use.
Quick answers
Can I use plug-in solar in Colorado today?
Colorado HB 26-1007 became law on May 7, 2026. It creates a state framework for portable-scale solar generation devices and limits utility approval requirements for qualifying systems. The statute does not erase electrical-code, safe-installation or property requirements, and common-interest-community provisions have their own effective timing.
Does buying a certified product make it legal?
No. Certification, state law, utility requirements, electrical code and property permission are separate checks.
Can a renter install a system?
Only after confirming the law and any lease, landlord, association, mounting and safety requirements.
