    Switch to solar with a system built for you.

      Solar can be a big investment. Our goal is to highlight companies that are best equipped to meet most Denverites’ energy needs. Here’s what residents should look out for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.

      NOTE: President Trump’s “One Big Beautiful Bill,” signed in July of 2025, phases out the federal solar tax credit. You now only have until Dec. 31, 2025, to install a system and get the 30% solar tax credit.

      Key insights

      Solar panel costs in Denver

      A typical solar panel installation costs anywhere from $9,920 to $28,342 in Colorado. Prices in Denver are comparable, ranging from $10,030 to $28,656.

      This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing, like at night or during outages. It’s worth considering if your area gets frequent blackouts.

      System size is the other major solar cost factor. The average Denver household needs a system with a capacity of 4.9 kW (kilowatt) to fully offset its electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.

      How can I pay for solar panels?

      Getting solar panels is like buying a car. Most people pay cash, finance or lease.

      • Solar loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright.
      • Solar leases are a good option if you have limited savings and don’t want to take on debt. A potential downside to leasing is that you won’t be eligible for the federal solar tax credit.

      Is solar worth it in Denver?

      Solar panels are generally worth it in Colorado if you like the idea of lowering your monthly utility bills. On average, Denver homeowners with solar panels can avoid $39,344 in total utility costs over 25 years.

      As long as your house is a good candidate for solar, it’s at least worth considering. Higher elevation means more intense sunlight will meet the surface of your solar panels. This increased solar exposure can enhance their efficiency, making Denver an ideal location for solar energy production.

      Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

      We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator that may also be helpful.

      The main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 11.05 years to break even (when your savings with solar panels make up for the cost).

      Potential roof problems

      As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This is an expensive and frustrating process.

      How to find a reputable solar company in Denver

      In our experience, the best solar companies in Colorado have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

      • Check certifications: The Colorado Solar & Storage Association’s COSSA Member Directory is a good place to start. You can verify a solar installer’s electrical license with the Colorado Department of Regulatory Agencies. We also recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).
      • Read reviews: Avoid companies with recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication.
      • Ask questions: Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

      Solar incentives in Denver

      The federal solar investment tax credit (ITC) is still the best incentive for most homeowners. It reduces your federal tax liability by 30% of how much it costs to install solar panels. You can combine the ITC with local solar incentives in Colorado to maximize savings.

      For instance, Xcel Energy has the Solar*Rewards program, which is a performance-based incentive for homeowners and business owners. You also don't have to pay sales tax on solar panels and other renewable energy equipment.

      Federal solar tax credit expires at the end of 2025

      The ITC is now set to expire at the end of the year, much earlier than previously scheduled. The credit was expected to drop gradually, then fully expire in 2035 — but those future step-downs have been eliminated under the “One Big Beautiful Bill,” signed in July of 2025. This means you have until Dec. 31, 2025, to install and pay for a system to qualify for the 30% credit.

      Denver solar FAQ

      How does the federal solar tax credit work?

      The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income.

      For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $5,000 in taxes, the $3,000 credit reduces what you owe to $2,000.

      Any unused portion rolls over to the next tax year. However, it’s possible to get a refund check if the ITC credit reduces your taxes to the point where you overpaid during the year.

      Will solar panels make my property taxes go up?

      No. Solar installations are exempt from property tax assessments in Colorado, meaning the value added to your home by solar panels won’t increase your property taxes.

      How does net metering work in Denver?

      Net metering lets you draw power from the grid when your solar panels aren’t producing enough. In return, you can send excess energy back to the grid for credit. These credits can then be used to offset your electricity bill when your solar panels are not producing enough energy.

      If you use Xcel Energy, you’ll be compensated for each kilowatt-hour of surplus solar-generated electricity supplied to the local power grid. Credit rates are based on the electricity rate during that specific time, making on-peak credits more valuable than off-peak ones. Any excess energy at the end of the billing period is carried over to the next month.

      What are the different types of solar panels?

      Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.

      Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient the solar panels you buy are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.

      Denver is prone to hailstorms, so homeowners should consider installing solar panels that are certified for impact resistance to withstand damage from hail.

      Can I get solar panels for free in Denver?

      We’re not aware of a totally free solar option in Denver. You can lease solar panels with minimal upfront costs, but there is usually an ongoing monthly fee.
