The seasonal swing is large here
Vermont sits far enough north that daylight hours vary substantially across the year, and winter brings both low sun angles and snow cover on panels.
Household consumption often moves the other way, particularly for homes with electric heating or a heat pump, where the heaviest demand falls when the array produces least.
That is not a reason against solar in Bennington; it is the reason the compensation arrangement matters. Vermont net metering compensation, built from a blended residential rate, is what bridges the gap.
It does mean an annual total conceals more here than in a milder state. Ask for the production estimate month by month rather than as a single figure.
Snow, tilt and the shoulder seasons
Ask what snow allowance the production model applied and how it was derived. Snow cover produces no electricity at all until it clears, and how quickly it clears depends on tilt and orientation.
Ask about tilt specifically. A steeper tilt sheds snow more readily and shifts output toward spring and autumn, which in a northern climate is often a better trade than maximising a summer peak.
Ask about the mounting and whether shed snow would land somewhere it causes a problem, such as over a walkway or an entrance. That is easier to solve at design stage than afterwards.
Ask what the model assumed about degradation over the system life. A model holding production flat across twenty-five years overstates the back half of the projection.
Sizing against the seasonal profile
Because Vermont compensation is built from a blended residential rate rather than an avoided cost figure, sizing here is less punishing than in states that pay wholesale rates for export.
That said, ask what percentage of your annual usage the design covers, and ask how generation beyond that is treated under your utility tariff.
Ask for the monthly profile with production and consumption shown together, so you can see how much of the year the system covers and how much it does not.
A heat pump is the most plausible reason for a Vermont household to size ahead, because it genuinely raises winter consumption. That is worth modelling rather than assuming, since winter is when the array produces least.
What belongs in a Vermont projection
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase in Bennington receives no federal tax credit.
Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask what a provider claims and what reaches you in the rate.
What exists is net metering compensation under Rule 5.100 built from a blended residential rate and two adjustors, and the electricity you stop buying.
Ask for a monthly production and consumption profile with a stated snow allowance, the tilt decision explained, and degradation applied across the term.
