What Are the Available Solar Incentives in Vermont?

Vermont offers multiple solar tax rebates and incentives to make going solar more affordable. Here are some of the key incentives Vermonters can benefit from.

Federal Solar Tax Credit

Net Metering in Vermont

Other State Solar Rebates

All homeowners who own their solar panels qualify for the federal tax credit. This program provides a tax credit equal to 30% of your solar installation costs. It also applies to stand-alone solar battery installation. The federal tax credit is not a rebate or cash payment. Instead, it helps to reduce or eliminate any owed federal taxes at tax time.

Net metering is a billing policy that lets you reduce your energy bills by sending excess energy your system generates to the power grid. Contracts vary based on how much power your solar panels produce and your local utility company’s rate. Green Mountain Power has the top net metering program in Vermont.

Here are some smaller tax incentives you can use to lower costs. 

  • Bring Your Own Device (BYOD) Program: Popular energy company Green Mountain Power awards up to $10,500 to qualifying applicants who purchase a solar battery.
  • Home Solar System Sales Tax Exemption: The Vermont Department of Taxes prevents you from paying the state’s 6% sales tax on solar equipment.
  • Renewable Energy System Property Tax Exemption: Installing a solar energy system boosts your home value, which typically comes with increased property taxes. However, Vermont’s property tax exemption eliminates these additional taxes.

What Should You Look For in a Solar Company?

There’s a lot of information to sift through to find the right solar provider for your needs. Here are some things to consider when comparing solar panel companies.

Solar Services

Warranties

Payment Options

Customer Support

We suggest looking for companies that offer additional services beyond just solar panel installation. Many companies also install solar batteries or provide system monitoring for ongoing support. These additional services show the company is committed to ensuring you get the most from your solar system and will treat your project as a long-term investment.

A quality solar provider will include a 25-year equipment warranty. Solar panels last an average of 25 years, so this ensures they’re covered throughout their lifetime. We recommend looking for providers that also include 25-year manufacturer (or product) warranties and workmanship coverage. Some solar installers include power performance guarantees that promise a certain level of power output for a particular time frame.

If you have the up-front capital or a great credit score, we recommend purchasing solar panels in cash or taking out a solar loan. These options offer the best return on investment (ROI) because they make you the system owner and qualify you for federal and state solar incentives. 

Solar leases and power purchase agreements (PPAs) offer fewer financial advantages because the solar company remains the system owner. This means you can’t qualify for solar incentives.

Consider solar companies that provide various ways to contact customer support, including phone, email, and an online chat or service form. Also, check if the company offers emergency repairs or ongoing system maintenance.

Offering educational materials online, such as an online blog or videos, is a sign that a company cares about keeping its customers knowledgeable and informed.


How To Get a Solar Quote in Vermont

You can follow these easy steps to get a solar quote in Vermont. The process typically only takes a few minutes.

  1. Contact the solar company: Contact the solar company online or by phone. We spoke with a representative who verified we were eligible for solar and that the installer serviced our area. You’ll need to provide your address for confirmation. Then, you’ll set up a time for a consultation either in-person or virtually so the company can begin the design process.
  2. Assess your energy needs: During your consultation, you’ll provide your monthly energy bills to help determine your needed system size and power. We recommend having at least three months of statements handy for your consultation to account for seasonal fluctuations.  
  3. Review your home design and roof space: A company representative will assess your roof space and condition and recommend any required repairs or updates. A virtual consultation may use satellite imaging to assess your home design, but the results can be less accurate.
  4. Build your project: The solar company will provide a final, itemized quote with a detailed inventory of all required equipment. You can add solar batteries or electric vehicle chargers to your system if your installer offers them. Review your quote for pricing and warranty information. You’ll also discuss available financing options and local solar incentives during this step.

Our Conclusion

SunPower is our top-recommended solar company in Vermont. It offers some of the most efficient solar systems available, guaranteeing long-term performance and energy savings. We also like that it uses in-house components to create a streamlined system designed for peak production. 

We recommend getting quotes from at least three providers to compare products, warranties, and additional services.
