Vermont's residential solar market is mature despite small size. Green Mountain Power's progressive storage programmes (Bring Your Own Device battery incentive, Resilient Home programme) have made storage-attached installations a larger share of new work than most states. Group Net Metering supports community solar and multi-household arrays.

Incentives

State and local solar incentives in Vermont

Beyond the 30 percent federal Residential Clean Energy Credit, which applies in every US state through 2032, Vermont has these state and local programmes.

Vermont Clean Energy Development Fund incentives

The Clean Energy Development Fund provides periodic incentives for residential solar. Current programme structure varies; confirm with the Vermont Department of Public Service before quoting.

Green Mountain Power Bring Your Own Device battery incentive

GMP pays residential customers an upfront incentive (up to $10,500 for a Powerwall-class battery as of 2025) in exchange for allowing GMP to use the battery during grid stress events. The incentive makes storage-attached installations substantially more affordable; some installations are effectively cash-flow positive from day one.

Group Net Metering

Vermont permits a single solar installation to credit multiple customer accounts under the Group Net Metering rules. This supports community solar farms, multi-family housing, and shared arrays among neighbours. The programme is unique to Vermont and a few other states.

Sales-tax exemption

Vermont exempts residential solar PV equipment from the state's 6 percent sales tax under the renewable energy equipment exemption.

Permits and interconnection

Permits and interconnection

Permit timelines in Vermont are generally fast. Most towns handle residential solar permits in 1 to 4 weeks via the state-level Certificate of Public Good process (expedited for systems under 150 kW). Burlington and Montpelier may take 3 to 5 weeks. SolarAPP+ is not accepted. Interconnection with GMP typically runs 3 to 5 weeks post-install.

Questions people ask

Solar in Vermont: FAQ

Does Vermont have net metering?

Yes, under Public Utility Commission rules. Residential solar exports credit at a 'blended rate' close to retail with specific adjustments for project size and location. Monthly rollover; annual true-up. Group Net Metering permits a single installation to credit multiple customer accounts.

What is Green Mountain Power's Bring Your Own Device programme?

GMP's Bring Your Own Device (BYOD) programme pays residential customers an upfront incentive (up to $10,500 for a Powerwall-class battery as of 2025) in exchange for GMP's right to use the battery during grid stress events. The incentive makes storage-attached installations substantially more affordable and sometimes net-positive from day one.

How much does solar cost in Vermont?

Residential solar in Vermont averages around $3.10 per watt installed, meaning a typical 7 kW system costs about $21,700 gross. After the 30 percent federal tax credit and any applicable GMP BYOD battery incentive for storage-attached systems, net cost is approximately $11,000 to $15,000.

Is solar worth it in Vermont?

Yes for most Vermont homes with suitable roofs. The combination of retail-rate net metering, strong GMP storage programmes, and the federal tax credit makes residential solar payback typically 8 to 12 years for solar-only and faster for storage-attached under BYOD. Winter snow derating stretches payback; honest annual yield modelling matters.
