As energy costs continue to rise, more Vermonters are turning to solar power to reduce their electricity bills and carbon footprint. With some of the highest electricity rates in the nation, going solar in Vermont can lead to substantial long-term savings. The state also offers generous incentives, including tax exemptions, that make solar adoption even more appealing. In this article, we’ll dive into the costs of going solar in Vermont, the top incentives available, factors that impact solar panel performance, and the best local solar companies to consider in 2024.

Solar System Costs in Vermont

According to 2024 data, the average cost of installing solar panels in Vermont ranges from $10,000 to $15,000 for a typical 5 kW residential system. On a per-watt basis, Vermonters can expect to pay between $2.62 and $3.54. While these figures are higher than the national average, the state’s strong solar incentives and high electricity rates still make going solar a smart financial move for most homeowners.

System SizeAverage Cost (After 30% Federal Tax Credit)
3 kW$6,593
5 kW$12,636
10 kW$21,978

Over 25+ years, the average Vermont homeowner can expect to save $26,468 by going solar. With a cash purchase, the typical payback period is around 10 years.

Applying the 30% federal tax credit reduces the average cost to $12,636 for a 5 kW system. Typical costs after the tax credit range from $6,593 for a 3 kW system to $21,978 for a 10 kW system. Factors like system size, panel type, and your location within Vermont can all impact the final price.

Homeowners have several financing options to make going solar more affordable:

  • Cash purchase: Paying upfront provides the best long-term savings and shortest payback period.
  • Solar loans: Many installers partner with lenders to offer $0-down, low-interest financing.
  • Solar leases and power purchase agreements (PPAs): These arrangements require no money down but provide lower savings compared to ownership.

Over 25+ years, the average Vermont homeowner can expect to save $26,468 by going solar. With a cash purchase, the typical payback period is around 10 years.

Vermont Solar Incentives

Vermont offers some of the most generous solar incentives in the country, making it easier for residents to afford the upfront cost of installation. Key incentives include:

Federal Solar Tax Credit

Deduct 30% of your solar installation costs from your federal taxes. For the average Vermont system, that’s a savings of $5,166. Available through 2032 before stepping down to 26% in 2033 and 22% in 2034.

Net Metering

Vermont has a statewide net metering program that credits you for excess solar electricity sent to the grid. Green Mountain Power offers one of the top net metering rates, compensating customers at the full retail rate for their surplus generation.

Factors Affecting Solar Panel Performance

When evaluating solar for your Vermont home, it’s important to consider the factors that will impact your system’s energy production:

Climate and Weather

Vermont sees an average of 111 sunny days per year, below the U.S. average of 205 days. However, even on cloudy days, solar panels continue to generate electricity, just at a lower rate. Vermont’s cold winters can actually boost solar panel efficiency, as PV performance improves in lower temperatures. Snow can temporarily block sunlight from reaching your panels, but they are designed to shed snow quickly once the sun returns.

Roof Characteristics

The ideal roof for solar has a south-facing orientation and a 30-degree tilt. However, east- and west-facing roofs can still be viable for solar. Shading from nearby trees or buildings can reduce energy production, so it’s important to assess your roof’s solar potential throughout the day. Your installer can help determine if any obstructions will significantly impact your system’s output.

System Design

Proper solar panel sizing and design are critical for maximizing your energy production and savings. A knowledgeable installer will take into account your energy usage, roof space, shading, and local climate to recommend the optimal system size and configuration. Investing in high-efficiency panels and quality inverters can also boost your system’s performance and reliability over the long term.
