    Switch to solar with a system built for you.

      We’ve heard from more than 100,000 verified solar customers since 2018. A couple of things we know for sure: People like powering their homes with a reliable source of cheap, clean energy. They don’t like getting into solar contracts that don’t meet their expectations. Here’s what to expect and what to look out for when buying solar panels in Vermont.

      Key insights

      How to choose a solar company in Vermont

      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.

      In our experience, the best solar energy companies have a few things in common: great reviews, quality equipment and solid warranties.

      1. Compare quotes

      Get multiple quotes from different solar companies to compare prices and services. Be cautious of companies that provide significantly lower quotes than others — this may indicate lower quality.

      » TIPS: Get the best solar quotes

      2. Check licenses

      The State of Vermont does not mandate any certification or licensing requirements specifically for solar power system installers. However, Renewable Energy Vermont (REV), a prominent industry association, has curated a directory of solar installers servicing the state.

      Watch out for door-to-door solar scams that attempt to gather your personal information.

      Solar companies listed in the REV directory maintain active general liability insurance coverage with a minimum of $1 million in policy limits. This ensures that homeowners are protected in the event of unforeseen incidents during the installation process.

      It’s a bonus if the company also has NABCEP-certified installers.

      3. Read the fine print

      Review proposals and financials carefully, understand legal considerations and ask about maintenance before signing an agreement with any solar company. If you don’t understand the payment terms, warranty or ongoing services, ask the representative.

      How much does it cost to go solar in Vermont?

      Average solar panel costs in Vermont typically range between $10,319 and $27,666. The size of your solar panel system is a big factor in your total cost. 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 Vermont, the average cost per watt is $2.77.

      The table below doesn’t include the cost of a solar storage battery, which sometimes costs as much as the panels. Solar batteries are a must if you want real energy independence and essential if you go off-grid. Permitting, utility fees and maintenance also add to the cost of going solar.

      How can I pay for solar panel installation?

      Getting solar panels is similar to buying a car. You could pay cash, but many people finance their system through a solar loan. If you have enough savings to pay upfront, the biggest advantage of paying upfront is avoiding interest charges.

      Leasing solar equipment is an attractive option for people who don’t want to get a loan or be responsible for maintaining a system.

      Vermont also has legalized power purchase agreements (PPAs), which work very similarly to leases.

      Solar incentives in Vermont

      The federal solar investment tax credit (ITC) is now set to expire at the end of the year, much earlier than previously scheduled. This means you have until Dec. 31, 2025, to install and pay for a system to qualify for the 30% credit.

      The ITC expired at the end of 2025.

      Additional statewide residential solar panel incentives in Vermont include a sales tax exemption and a property tax exemption.

      You might also be eligible to enroll in net metering, which lets you earn credits for sending any excess solar energy to the grid. These credits can offset the cost of electricity consumed at other times.

      FAQ

      Are solar panels worth it in Vermont?

      For many, going solar in Vermont is worth it for lowering energy costs. On average, Vermont homeowners with solar panels can avoid $41,197 in total utility costs over 25 years.

      Patricia in Burlington put it this way: “I don't see any downsides at all in going solar. You’re always saving money.” For others, it’s more about reducing reliance on local power companies or helping the environment.

      However, the return on investment also depends on the efficiency and size of your system. Assuming an upfront purchase, it takes about 12.84 years to break even (when your savings with solar panels make up for the cost). If you finance, it’s worth it if your loan payment is cheaper than your current utility bill.

      » STILL NOT SURE? Solar energy pros and cons

      Can I get free solar panels in Vermont?

      We’re not aware of a totally free solar option in Vermont. Scams that promise free solar panels can end up costing consumers quite a bit of money.

      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. We recommend using NREL’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.

      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.

      Should I replace my roof before installing solar panels?

      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 will cost around $5,000 for a 19-panel setup.

      » SHOULD YOU: Replace your roof before going solar?

      Is my HOA allowed to restrict solar panel installations?

      No, Vermont laws protect your right to install solar panels and other renewable energy devices on your property. Homeowners associations can’t restrict their installation.
