What Vermont pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Vermont's current rule in plain words, with the official source.
Under Vermont's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Derby Line homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Derby Line, Vermont has about 670 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
Whether solar still pays in Vermont after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.
The honest 2026 answer for Derby Line: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Vermont's export compensation, covered in the net metering section.

Vermont rules that decide your payback
| Rule | Vermont status |
|---|---|
| Export compensation (net metering) | Vermont pays net-metering customers a bill credit built from three PUC-set numbers - a statewide blended residential rate plus a REC adjuster and a siting adjuster - and effective August 1, 2026 the blended residential rate rises to $0.2071/kWh, with the siting adjuster for Category I systems (up to 15 kW, the typical residential size) at negative $0.05/kWh and the REC adjuster at $0.00/kWh if you transfer your renewable energy credits to your utility. |
| State incentive | Net-metering rate adjusters set by the Vermont Public Utility Commission under Commission Rule 5.100 / 5.128 (biennial update), which function as the state's net-metering incentive; no separate state rebate verified. |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
Keeping your renewable energy credits costs you money: if you retain the RECs instead of transferring them to your utility, a REC adjuster of negative $0.04/kWh is applied to ALL kilowatt-hours your system produces - including the power you use on site, not just what you export - and it shows up as a charge on your bill. Also, timing matters: a complete certificate of public good application had to be filed on or before July 31, 2026 to lock in the prior incentive levels, since the new adjusters apply to systems whose complete CPG application is filed on or after August 1, 2026.

Getting Derby Line quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
