    “The installation of our Ion Solar was very quick and painless. They've been very helpful as well.”
    James Cheyenne, WY

    Some reviewers in other states mentioned communication issues or delays during the installation process. We think ION Solar could be a little more transparent about its financing options and additional services provided. The company also doesn’t perform maintenance or repair services.

    ION Solar operates in several states, including Wyoming. The company employs NABCEP-certified professionals, a nationally recognized credential for solar installation expertise. Installers use Silfab solar panels (premium monocrystalline panels designed for performance and curb appeal) and Enphase microinverters. Most projects are completed in 60 to 90 days.

    Project Solar reps take a no-sales-gimmicks approach that appeals to more budget-conscious solar clients. We like that pricing is competitive and transparent. As of August 2025, projects start at $1.61 per watt — that’s about half the average cost per watt in Wyoming. For homeowners comfortable with hands-on planning and oversight, it’s the cheapest way to go solar in Wyoming.

    Customers seem generally satisfied with the quality of the products Project Solar offers and the savings they see on their electricity bills.

    “Project Solar is practical. They're well-priced, and they work with their customers. It's a great company.”
    Janet Lyman, WY

    Project Solar does not offer professional installation in Wyoming. It’s strictly a DIY option, which means you’ll need to handle permitting, inspections and the physical installation (or hire your own local electrician). If you're not confident managing a project or troubleshooting issues, the risk of frustration or errors is high.

    Switch to solar with a system built for you.

      We’ve heard from over 100,000 verified solar customers since 2018. Here’s what we’ve learned: People love cutting their energy bills with clean, reliable power. But they hate ending up in solar contracts that don’t deliver. In Wyoming, where electricity rates have traditionally been low but are now rising fast, it’s more important than ever to understand what you’re buying. This guide breaks down what to expect from solar in Wyoming, how incentives and utility policies affect your savings and what to look for in an installer so you can avoid surprises.

      Key insights

      In Wyoming, a typical residential solar panel system costs $12,365 to $35,328, depending on the size of your system and what financial incentives you qualify for.

      Jump to insight

      The federal investment tax credit (ITC) is the most significant financial incentive for buying solar panels in Wyoming. You can also lease a system with little upfront cost, but you aren't eligible for the ITC.

      Jump to insight

      Many solar customers are happy with the service, installation and cost savings. Others felt misled by pushy sales tactics and ended up with monthly bills higher than expected. Watch out for false advertising and door-to-door scams that attempt to gather your information.

      How to choose a solar company in Wyoming

      To choose a solar company in Wyoming, look for a provider that understands the state’s unique solar landscape. Great reviews, transparent contracts, reliable equipment and comprehensive warranties are also important factors to consider. The best installers combine technical experience with local knowledge around regulations, permits and available financial incentives.

      Follow these steps to find a solar company in Wyoming that fits your needs:

      • Check certifications: Look for companies with NABCEP-certified installers. This nationally recognized credential signals technical expertise and a commitment to quality.
      • Read reviews: Research the company's track record and read reviews. Look out for red flags — complaints about misleading sales tactics, equipment failures, billing issues and lack of communication are common themes in negative solar company reviews.
      • Get quotes: Get multiple solar quotes from different companies to compare prices and services. Be cautious of companies that provide significantly lower estimates than others — this often signals outsourced labor, weak warranties or lower-grade equipment.
      • Ask questions: Ask if the company handles storage batteries, EV chargers, monitoring software or critter guards. Many Wyoming homeowners opt for backup batteries due to remote locations or grid unreliability. It’s also smart to ask about critter guards in Wyoming.
      • Read the fine print: Carefully review proposals and financials, understand legal considerations and ask about maintenance before signing an agreement with any solar company. If you don’t understand something about the payment terms, warranty or ongoing services, ask.

      Solar panels last a long time — you want to hire a well-established company that will still be around for system support for at least 25 years.

      Going solar in Wyoming

      Wyoming does not require special solar licensing, but installers must be licensed electricians — either master, journeyman or apprentice — working under a Wyoming-licensed electrical contractor. Always ask who will be performing the installation and confirm their licensing status.

      How much does it cost to go solar in Wyoming?

      Average solar panel costs in Wyoming typically range between $12,365 to $35,328. The total cost of solar installation depends heavily on the system size. It also depends on what incentives you’re eligible for, the condition of your roof and how much sunlight exposure it gets.

      Most installers set the price according to the system's wattage, with a typical cost between $2.50 and $5 per watt. In Wyoming, the cost per watt is $3.53.

      Average solar panel costs by system size in Wyoming

      These figures cover equipment and labor but don’t include the cost of solar batteries, which can add $10,000 to $20,000 to your total price. Battery storage is essential for off-grid homes or anyone who wants backup power during outages.

      Other cost factors include permitting fees, interconnection charges, panel removal (if reroofing is required), and optional add-ons like critter guards, EV chargers and performance monitoring.

      How can I pay for solar panel installation?

      Buying solar is like buying a car: you can pay in full or finance it over time. Most Wyoming homeowners either pay cash or use a solar loan.

      • Cash purchase. Paying upfront avoids interest and gives you the fastest return on investment. It also maximizes your savings from the 30% federal tax credit.
      • Solar loans. Most installers partner with third-party lenders to offer solar loans with terms from 5 to 25 years. Monthly payments are often lower than your current utility bill, but you’ll pay more over time due to interest. Qualification is credit-dependent.
      • Solar leases and power purchase agreements (PPAs). Leases or PPAs can lower your upfront costs, but you won’t own the system, which means you don’t qualify for the tax credit and may see fewer long-term savings. However, leasing solar equipment is an attractive option for people who don’t want to get a loan or be responsible for maintaining a system.

      Not all companies offer all payment options. Always ask what loan terms and lenders they use, and whether you’ll be eligible for incentives based on ownership.

      » COMPARE: Leasing vs. buying solar panels

      Solar incentives in Wyoming

      The federal solar investment tax credit (ITC) reduces your federal tax liability by 30% of the cost of your solar energy system. This tax credit applies to both residential and commercial installations, and it includes the cost of the solar panels and other equipment, labor and additional features for monitoring the system.

      The ITC expired at the end of 2025.

      For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $15,000 in taxes, the ITC reduces what you owe to $12,000. You don’t get these benefits automatically, though. You have to claim your solar equipment, labor and permits on your federal taxes for the same year you started using your system on Form 5695.

      Don’t get confused: The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which reduces your taxable income. It isn’t a rebate or a refund. It only offsets your tax liability; you can't take advantage of the ITC if you don’t owe taxes in the first place. However, the credit rolls over to the next tax year if you don’t use the full amount.

      Be skeptical of claims about Wyoming solar rebates. No statewide solar tax credits or sales tax exemptions currently exist. Some rural customers may qualify for USDA REAP grants, but those are limited to agricultural producers and small businesses.

      Net metering in Wyoming

      Wyoming doesn’t offer upfront rebates, but most utilities participate in net metering, a billing program that credits you for excess electricity your solar panels send back to the grid. This helps lower your electric bill over time.

      Under state law, utilities must offer net metering for systems up to 25 kW, which covers nearly all residential setups. How it works varies slightly by provider, but the core structure is similar:

      To maximize value, size your system to match your annual energy usage.
      • Monthly credits: If your system generates more electricity than you use in a billing cycle, you earn a kilowatt-hour (kWh) credit. Utilities like Rocky Mountain Power and Carbon Power & Light roll these credits forward to offset your usage in future months.
      • Annual payout: At the end of the year, any unused credits are typically purchased by your utility at the avoided-cost rate — a wholesale price that's lower than what you pay. For example, Rocky Mountain Power’s avoided-cost rate is around 3 cents/kWh, compared with a retail rate of about 13 cents/kWh.

      Are solar panels worth it in Wyoming?

      Yes, solar panels are worth it in Wyoming, but only if you understand what you’re getting. Solar panels can save you thousands of dollars over time, especially as utility rates rise. But savings vary widely depending on your system size, roof conditions, electric usage and installer quality.

      Upfront costs in Wyoming are higher than in some other states, and low historical utility rates have made solar a longer-term investment. But that’s changing. Major utilities like Rocky Mountain Power raised residential rates by over 10% in early 2025, and more increases are likely. This makes solar more appealing as a way to lock in predictable energy costs.

      However, we’ve also heard about problems with leaks and roof damage caused by the installation of solar panels, leading to frustration and difficulties in getting repairs.

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

      It’s a common misconception that solar panels always eliminate your monthly power bill — this is not always the case. On the bright side, people who still have a bill after going solar typically pay significantly less than before.

      The return on investment of a solar panel installation depends on your system's efficiency and size. Assuming an upfront purchase, it takes about 14.49 years to break even (when your savings with solar panels make up for the cost).

      The general consensus is that solar panels are worth it in Wyoming. On average, homeowners can avoid $46,147 in total utility costs over 25 years.

      Solar is worth it in Wyoming if:

      • You plan to stay in your home for at least 10 to 15 years
      • You work with a reliable installer
      • You size your system carefully to avoid overproduction at avoided-cost rates

      There are pros and cons to going solar. It’s not a guaranteed payoff for everyone, but for many Wyoming homeowners, solar delivers both long-term savings and energy independence.

      FAQ

      How do I know if my house is a good candidate for solar?

      Plenty of unshaded roof space that faces south or west is best for optimal sun exposure. Solar photovoltaic (PV) technologies, more commonly known as solar panels, absorb sunlight and convert it into usable electricity. If you have a lot of shading around your house, they might not get enough sun to power your home.

      It’s also smart to upgrade any old, inefficient appliances first. Reducing your electrical loads now means you can get a smaller system, which will be cheaper.

      Use the National Renewable Energy Laboratory’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house — just type in your address. Project Sunroof is a free solar savings estimator powered by Google Earth imagery.

      Should I replace my roof before installing solar panels?

      As a rule of thumb, if it’s more than 10 years old, consider fixing your roof 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 will cost around $5,000 for a 19-panel setup.

      Can I get free solar panels in Wyoming?

      We are not aware of any legitimate programs for free solar panels in Wyoming. However, you can lease a solar energy system with little to no upfront costs. Just look out for scams that promise free solar panels — they can end up costing you quite a bit of money.

      What’s the difference between a solar broker and a solar installer?

      A solar broker is a middleman or intermediary who helps connect homeowners with solar installation companies. A solar installer specializes in designing, procuring and installing solar panels and related components. Ultimately, deciding between a broker and an installer depends on how much you want to be involved. A broker is helpful if you value convenience. If you want more control and potentially lower costs, working directly with a solar installer is best.

      How does net metering work in Wyoming?

      Net metering is a system of give-and-take between you and your utility company. It lets you access power from the grid when your panels don’t generate enough electricity.

      In Wyoming, some utilities may offer a kilowatt-hour (kWh) credit at the full retail rate, while others apply an avoided-cost rate, which could be lower than the retail rate. At the end of the year, the utility typically purchases any unused credits at the avoided-cost rate.

      How long does it take to install solar panels in Wyoming?

      Installation times depend on a range of factors, especially seasonality and supply chain issues. The actual installation might take only a day, but it takes time to design and plan, and you also have to activate the system.
