Summary

Consultants from GRP Wegman presented a preliminary plan to install 136 rooftop panels (≈48.1 kW) at Town Hall, estimating roughly 90% offset of usage, a total project cost just over $125,000 before incentives, and a payback of about six to seven years; council asked for the presentation and agreed to revisit the proposal at next month’s work session.

Consultants from GRP Wegman laid out a preliminary plan to install rooftop solar panels at Central Town Hall during Monday’s council meeting, saying the installation could cut the building’s electric use by roughly 90 percent and pay back the town’s investment in the medium term.

Mike Wilson, a GRP Wegman representative, said the company could place 136 panels on the town hall roof and emphasized long-term savings: "We're just taking advantage of the sun to reduce the power bill here," he said, adding that faster-rising utility rates make self-generation a practical hedge.

Eric, GRP Wegman’s electrical engineer, gave technical figures: "We're looking at 136 panels…with an AC system size of 48.1 kW," and he estimated annual production at about 79.3 megawatt-hours. He described a total project cost "just over $125,000," with an investment tax credit (ITC) returning roughly $37,000, producing a net capital cost near $87,000 in the company’s model. Eric also said the company includes an inverter-refresh plan (about every 10 years) and warranties panels for 30 years.

Council members asked about batteries and resiliency. Company representatives said batteries increase resiliency but currently add significant cost and can extend payback periods; they recommended batteries primarily for emergency operations centers. On the question of timing, GRP Wegman estimated a 60-day installation once a contract is signed.

Town staff asked the company to provide the presentation slides and supporting documents for council review. The council agreed to place the project on next month’s work session for further discussion and to review the emailed materials before taking next steps.

The presentation included explanations of procurement options (cooperative purchasing and tax-exempt lease purchase), a guaranteed-production clause that the company said it would back in contract, and examples of expected lifecycle savings: GRP Wegman estimated a net benefit over 30 years in their model, but stressed the town should review the full financial worksheets and procurement terms before committing.

The council did not authorize construction or sign a contract at the meeting; members voted to consider the proposal again at the next work session after receiving the consultants’ presentation and supporting documents.
