The "300 days of sunshine" in the Mile High City is more than a tourism slogan -- it is the primary weapon used by aggressive solar sales teams targeting homeowners from Highlands Ranch to Boulder. You have seen them in your neighborhood: reps promising you can "stop paying Xcel Energy" and "lock in 2024 rates forever." But as the 2026 energy landscape shifts, many Denver residents are realizing the math they were shown at the kitchen table does not match their actual bills.

Why Denver Homeowners Are Regretting Solar in 2026

• →The Xcel Rate Reality: Xcel Energy's Solar*Rewards credits and net metering policies have become more complex. Many homeowners find the "avoided cost" they receive for their power is far less than the retail rate they pay at night.
• →The Lien Surprise: Many Denverites are shocked to find a UCC-1 fixture filing on their property title when they try to refinance or sell in competitive markets like Wash Park or Cherry Creek.
• →Substandard High-Altitude Installs: Denver's intense UV rays and heavy snow loads require specialized mounting. Out-of-state crews unfamiliar with Colorado's climate cause frequent roof leaks and panel lift.
• →The "Free Solar" Deception: There is no "Colorado State Free Solar" program. If you were told the government is paying for your panels, you were likely misled into a high-interest private loan.

Colorado's New Consumer Protections for 2026

SB25-299: The New Standard for Solar Disclosures

This law requires solar companies to provide a clear, 4-page disclosure form before you sign. If you were not given this document, or if the "Welcome Call" required by law was skipped or forged, your contract may be legally voidable under the Colorado Consumer Protection Act.

Home Solicitation Sales Act (C.R.S. Section 5-3-402)

If a salesperson came to your door, you have a 3-business-day cooling-off period to cancel. If the company failed to provide the mandatory 10-point font "Notice of Cancellation," your right to cancel may technically still be open -- even months later.

"Click to Cancel" and Subscription Reforms

Colorado's 2025-2026 "Click to Cancel" rules require companies to provide a simple way to exit service agreements. If your solar provider is making it impossible to reach support or process a cancellation, they are in direct violation of state law.

Solar Companies We See Issues With in Denver

• →Sunnova: Flagged by the BBB in Denver for a pattern of complaints regarding service delays and misleading financing terms.
• →Tesla Solar: Known for leaving Colorado customers without support when inverters fail during winter.
• →Sunrun: Frequent issues with PPA escalators that make solar power more expensive than Xcel's grid power within a few years.
• →ADT Solar (formerly Sunpro): Since their exit from the industry, many Denver homeowners have "zombie systems" with no active warranty support.
• →Momentum Solar: Many disputes regarding aggressive door-to-door sales in Aurora and Thornton that misrepresented the federal tax credit.
