Solar Incentives in Vermont

Vermont's net metering, regulated by the Vermont Public Utility Commission (PUC), is among the most generous in the United States for residential customers. Tier 1 systems (≤ 15 kW residential) receive 1:1 retail-rate compensation plus a Renewable Energy Credit (REC) value adder. The adder varies by system size, technology, and whether the host is a residence vs preferred site. Larger Tier 2/3/4 systems receive lower compensation. Green Mountain Power (the dominant utility, covering ~75% of customers) operates the program alongside Vermont Electric Cooperative, Burlington Electric, Stowe Electric, and other municipals. The 20-year contract structure locks in compensation. Vermont's combination of high retail rates and the REC adder makes it one of the few states where post-ITC residential solar economics remain in the 7–9 year payback range.

Under Vermont law (32 V.S.A. § 3845), residential solar PV is exempt from local property tax assessment of the increase in value. Filing is via the local town assessor; some towns require homeowner application, others apply automatically. The exemption is permanent (lifetime of system). Vermont education property tax is also exempted under separate provisions.

Vermont sales tax exemption under 32 V.S.A. § 9741(46) covers solar PV equipment installed on residential or commercial property. Battery storage paired with PV is generally covered when supplied as part of a single bundled service. The installer applies the exemption at point of sale; no separate filing required. Standalone DIY equipment purchases without an installation service may require alternate exemption documentation.
