The Residential Clean Energy Credit lets people claim a tax credit worth 30% the cost of a solar panel system in the year it’s installed. The credit can only be used against taxes you owe or have already paid that year, but any excess credit can be rolled over to future years.

The credit is broadly available, though there are a few restrictions — you must own the panels and they must be on a house you live in — so be sure to consult a tax professional about your situation.

Colorado’s Property Tax Exemption for residential solar systems eliminates property taxes on qualifying solar equipment installed on your home. This means you won’t pay any additional property taxes on the value of your solar panels, inverters, and related equipment, even though these systems typically add significant value to your property.

To qualify for this exemption, your solar system must be installed on residential property, owned by you (the homeowner), produce electricity primarily for your home’s use, and have a capacity of no more than 100 kilowatts of AC electricity. The exemption applies only to the solar equipment itself – not your underlying property. There are no specific deadlines mentioned, but the system must meet all criteria to maintain the exemption. It’s important to note that this exemption is automatic for qualifying systems, and while Colorado doesn’t offer statewide property tax incentives, some local counties and municipalities may provide additional rebates or credits for renewable energy installations.

Colorado’s Sales Tax Exemption for renewable energy components allows homeowners to avoid paying state sales tax when purchasing solar equipment for their home. This exemption applies to essential solar system components including solar panels (modules), inverters, mounting racks, wiring, control systems, and other equipment needed to generate electricity from solar energy. The exemption helps reduce the upfront cost of going solar by eliminating the state’s sales tax burden on these qualifying components.

The financial benefit varies based on your local tax rates, but you’ll save the applicable state sales tax percentage on all qualifying solar equipment purchases. The exemption applies to Colorado state sales tax and certain special district taxes like RTD and Scientific and Cultural Facilities District taxes. However, it’s important to note that most city and county sales taxes are not included unless your local municipality has specifically adopted this exemption through their own ordinance. The exemption does not cover labor costs, energy storage systems like batteries, or remote monitoring equipment, and it only applies to components up to the generator step-up transformers at your property.

The Fort Collins Solar Rebates program is a utility incentive that helps residents reduce the upfront cost of installing solar panels and battery storage systems. Fort Collins Utilities offers cash rebates to customers who install qualifying solar equipment through their network of approved contractors. The program is designed to make solar more affordable while helping the city meet its renewable energy goals.

The financial benefits include a $200 per kilowatt rebate for solar installations (up to $1,000 maximum) and a $150 per kilowatt-hour rebate for battery storage (up to $3,000 maximum). The combined maximum rebate for a new system is $4,000. For example, a typical 5-kilowatt solar system would qualify for the full $1,000 solar rebate. These rebates are provided as checks after the system passes final inspection and are in addition to the 30% federal tax credit available through 2032.

To qualify, you must be a Fort Collins Utilities electric customer and work with one of their participating solar contractors. Your system must be at least 500 watts in size and meet all interconnection standards. The program requires you to assign the renewable energy credits from your system to the utility for 20 years in exchange for the rebate. Systems must be installed within six months of receiving approval, and you’ll need to manage any tree shading that might affect your panels between 9 a.m. and 3 p.m.

Important considerations include that rebate amounts may be reduced if your system produces less than 90% of optimal output due to shading or poor orientation. The program also offers on-bill financing through Epic Loans, and Fort Collins Utilities recommends completing an energy efficiency assessment before installing solar to maximize your investment. The utility maintains a list of approved contractors who understand local rates and requirements, ensuring a smoother installation process.

The San Miguel Power Association (SMPA) Solar Rebates program offers cash rebates to help members reduce the upfront cost of installing solar photovoltaic systems. This utility program provides $0.10 per watt for both residential and commercial solar installations, making clean energy more affordable for homeowners and businesses in SMPA’s service area.

Residential customers can receive up to $300 (for systems up to 3kW), while commercial customers can receive up to $1,000 (for systems up to 10kW). The rebate application must be completed by your solar contractor on your behalf – individual homeowners cannot apply directly. Your contractor doesn’t need to be pre-registered with SMPA, but they must meet certain eligibility requirements and handle all the necessary paperwork. The program mentions that deadlines apply, so it’s important to work with your contractor to submit applications promptly after installation.

The Xcel Energy Solar* Rewards Program – Low Income is a utility incentive program designed to make solar energy more accessible for qualifying low-income households in Colorado. This program provides financial assistance to help reduce the upfront costs of installing solar panels, making clean energy more affordable for families who might otherwise be unable to access solar power.

Unfortunately, the official source information provided appears to be incomplete or corrupted, so specific details about the financial benefits, exact eligibility requirements, and program deadlines are not available from the source material. Typically, utility solar programs for low-income customers offer rebates, reduced rates, or special financing options. Interested homeowners should contact Xcel Energy directly to learn about current incentive amounts, income qualification thresholds, application processes, and any program capacity limits or deadlines that may apply.

The Xcel Energy Solar* Rewards Program – Renewable Battery Connect is a utility program that pays Colorado homeowners for allowing Xcel Energy to use their home battery storage systems during times of high electricity demand. When you have a qualifying battery system connected to your solar panels, Xcel can remotely access stored energy from your battery to help balance the electrical grid during peak usage periods.

Unfortunately, the official program details including specific financial benefits, eligibility requirements, and deadlines are not accessible from the provided source. To get complete information about payment rates, battery system requirements, enrollment deadlines, and participation terms, homeowners should contact Xcel Energy directly or visit their website. This type of program typically requires you to have an approved battery storage system and may have specific technical requirements for grid connectivity and remote access capabilities.

The City of Boulder Solar Tax Rebate is a local incentive program that helps residents and businesses recover some of the sales tax they paid when installing solar electric or solar thermal (hot water) systems. This rebate program, established in 2008, allows property owners to get back approximately 15% of the city sales and use tax they paid on materials and permits for their solar installation.

To qualify for this rebate, you must be a Boulder resident or business owner who has completed a solar installation on your property. The most important requirement is timing – you must submit your rebate application within 12 months of the city’s final inspection of your solar system. You’ll need to complete the Solar Tax Rebate Application and Affidavit of Legal Residency, then mail these forms along with your project receipts and a copy of your ID to the city’s Finance department. Keep in mind that rebates are subject to funding availability, so it’s wise to apply as soon as possible after your installation is complete.

Net metering in Colorado allows homeowners with solar panels to receive credit for excess electricity they generate and send back to the grid. When your solar system produces more power than your home uses, the extra electricity flows to the grid and you receive credits on your utility bill. These credits can then be used to offset electricity you consume from the grid when your solar panels aren’t producing enough power, such as at night or during cloudy days.

The financial benefits vary by utility company, but most Colorado utilities offer 1:1 net metering, meaning you receive full retail rate credit for each kilowatt-hour of excess solar energy you produce. Credits typically roll over month to month, and at the end of each year (usually in March or April), any remaining credits are either cashed out at a lower rate (ranging from 1.5 to 5.5 cents per kWh depending on your utility) or can continue rolling over indefinitely. Some utilities like Xcel Energy and Black Hills Energy give customers the choice between annual cash-out or indefinite rollover, while others automatically cash out credits annually. It’s important to note that if you choose indefinite rollover and later move homes, you’ll forfeit any unused credits, so the cash-out option may be better for customers planning to relocate.

Leasing Solar Panels

Boulder homeowners have access to Power Purchase Agreements (PPAs) through multiple utility providers including Xcel Energy, United Power, Black Hills Energy, Colorado Springs Utilities, CORE Electric Cooperative, Grand Valley Power Cooperative, and DMEA.

With a PPA, you pay for the actual electricity your solar panels produce at a fixed rate per kilowatt-hour rather than a monthly lease payment. This means your bills vary seasonally – higher in summer when panels produce more, lower in winter – but your annual savings remain consistent compared to traditional utility rates.

Unlike purchasing solar outright, PPAs eliminate upfront costs, maintenance responsibilities, and system performance risks. Palmetto handles all equipment, installation, monitoring, and repairs while you simply enjoy clean energy at predictable rates. Learn more about solar financing options or explore our LightReach program for immediate savings without any investment.
