Blue Raven received 4.4 out of 5 stars according to our rating system. The company scored the most points for its customer service reputation and warranty coverage. It also earned points for providing all standard solar panel services but lost some due to its limited financing options and lack of roof leak coverage.

Solar Energy World
Solar Energy World (SEW) is one of the most robust and well-regarded solar installation companies. It boasts several impressive features, such as its 30-year manufacturer’s warranty. Its service area is limited, and it doesn’t offer energy auditing services. We like that SEW discloses what solar panels it primarily works with and that the panels are from trusted, quality brands such as Qcells and Silfab.

SEW offers a 30-year manufacturer’s warranty on all its solar panels and inverters, whereas many providers only offer 25-year warranties.
- Solar Equipment and Services (18 out of 25 points): The company is an ideal option for many basic solar products and services, such as solar panels and battery installation. It lost points because it doesn’t install EV chargers or perform energy audits.

Sunrun
We like Sunrun for its four financing options, including its unique leasing options if you don’t want to own your system. This stands out to us because the other companies on this list don’t offer as many options.

- Solar Equipment and Services (15 out of 25 points): Sunrun provides solar panel and battery installation but uses third-party installers. Though this is becoming an industry standard, in-house installers typically yield better communication and quality. The company also doesn’t provide roofing services or energy audits but does offer quality active monitoring assistance.

What Are the Available Solar Incentives in Wisconsin?
Wisconsin tax incentives and rebates help make solar more affordable and further reduce your electricity bills. Our list details some of the state’s most significant incentives, but we recommend checking the Database of State Incentives for Renewables and Efficiency (DSIRE) for more localized, city-specific options.
Federal Solar Tax Credit
All Wisconsin residents qualify for the federal tax credit. This program allows you to claim 30% of your solar panel costs on your federal taxes. This also applies to stand-alone solar battery installations. The federal tax credit is not a rebate or cash payment. Instead, it helps to reduce or eliminate any owed taxes at tax time.
Net Metering in Wisconsin
Wisconsin’s net metering program is backed by the Public Service Commission of Wisconsin. This program allows you to send excess energy produced by your system back to the power grid in exchange for credits on your utility bills. Terms vary based on how much power your solar panels produce and your specific utility company’s rate. Xcel Energy provides one of the most extensive net metering programs in the state.
Other State Solar Rebates
Wisconsin legislation also offers the following incentives to reduce your up-front costs.
- Focus on Energy Home Solar Rebate: Wisconsin’s Focus on Energy Program provides residential solar customers with cash rebates for installing solar panels. It awards approximately $500 to Wisconsin homeowners in populated areas and up to $1,000 to rural residents.
- Solar Energy System Property Tax Exemption: Typically, solar panels increase your home’s value, resulting in higher property taxes. However, Wisconsin’s property tax exemption ensures that homeowners won’t face additional taxes due to their solar installation.
- Renewable Energy State Sales Tax Exemption: Wisconsin imposes a 5% sales tax on all purchases. However, the state’s solar sales tax exemption exempts any qualifying solar equipment from this tax. It applies to photovoltaic (PV) cells, modules, arrays, and any tracking equipment that maintains the system’s orientation to the sun.
What Should You Look For in a Solar Company?
Finding a reliable and reputable solar installer is essential, but there’s a lot of information to sift through. Consider the following factors to help you narrow down your choices as you compare solar companies.
Solar Services
Some companies focus solely on solar panel installation, while others offer several solar battery types, EV charger installation, and system monitoring. Some providers even offer energy audits to help improve your entire home’s efficiency. A company that provides these extras treats solar as a long-term investment rather than just a one-time installation.
Warranties
A strong warranty protects your solar investment and provides long-term reliability. Look for companies that offer 25-year warranties on both equipment and workmanship, covering the lifespan of your panels. Some providers also include performance guarantees, stating that your panels will produce a minimum amount of energy for a set period.
Payment Options
The best solar financial options include cash payments and solar loans, which provide ownership and access to tax incentives. Leases and power purchase agreements (PPAs) have lower upfront costs but limit financial benefits since the company retains ownership. Homeowners who purchase their system see the greatest return on investment through energy savings and incentives.
Customer Support
A good solar provider should offer multiple ways to get in touch, including phone, email, and online service requests. Access to responsive customer support is important for handling repairs, system monitoring, and maintenance. Companies that provide educational resources, like blogs and guides, are committed to customer knowledge.
How To Get a Solar Quote in Wisconsin
It’s easy to get a solar quote in Wisconsin by following the steps below. This process typically only takes a few minutes.
- Contact the solar company: Visit the company’s website and fill out an online quote form or call the customer support team. When we contacted solar companies for sample quotes, representatives verified our eligibility and confirmed that the installer serviced our area. You’ll need to provide your address for this confirmation. After speaking with a representative, you’ll schedule an in-person or virtual consultation.
- Assess your energy needs: During the consultation, you’ll review your average energy usage to determine the right system size. Have your most recent energy bill ready and, if possible, bring at least three months of statements to account for seasonal fluctuations. Some solar providers request multiple months of data to get a clearer picture of your energy consumption.
- Review your home design and roof space: The installer will assess your roof space to determine how many panels you need. They will also evaluate your roof’s condition and recommend any necessary repairs or upgrades. Virtual consultations use satellite imaging to estimate roof capacity and system compatibility.
- Build your project: You’ll receive a detailed, itemized quote outlining all required equipment, including solar panels, inverters, and any optional add-ons like battery storage or EV chargers. Review the pricing, warranty coverage, and financing options. The representative will also review available Wisconsin solar incentives to help you maximize savings.
Our Conclusion
We recommend All Energy Solar for Wisconsin homeowners. The company is NABCEP-certified and offers a wide range of solar products.
We suggest getting quotes from at least three providers before choosing. This will help you compare each provider’s products, warranties, and additional services.

FAQs About Solar Companies in WI
Is solar in Wisconsin worth it?
Yes, going solar is worth it in Wisconsin. The state has clear access to sunlight, numerous reputable solar installers, and several incentives to reduce installation costs.
Does hail damage solar panels?
Hail does not typically cause severe damage to solar panels. Most solar panel manufacturers design their products to withstand the elements in all weather conditions. However, more powerful storms may cause chipping or cracking, so we recommend working with a solar installer that offers maintenance services.
Does solar increase home value in Wisconsin?
Yes, solar panels increase home value in Wisconsin by an average of $15,000, according to a study conducted by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
What happens when solar panels are covered in snow?
Light snow has little effect on solar panels, given that wind can blow it off and light can still reach the panel. However, heavy snow that accumulates on panels can prevent them from generating power.
