DuPage County committee approves solar roof installation, pursues federal renewable tax credits

DuPage County’s facilities committee approved a contract to install phase two solar panels on the roof of the administration building and authorized county accounting consultants to pursue federal renewable energy tax credits tied to the project.

Committee members approved a not-to-exceed contract of $574,833 for the phase-two rooftop installation and separately approved a $23,500 contract with Baker Tilly to provide accounting services and support related to pursuing federal renewable energy tax credits under the Inflation Reduction Act of 2022. The committee also processed a rescission and re-award route for a smaller accounting contract (recorded as $16,370) tied to the same tax-credit work.

Discussion centered on project economics and funding. A committee member said, “I thought I heard we're making about $2,000 a month on solar,” reflecting the panel of comments during the meeting about current production. Presenters cautioned that pure solar payback without grants can be decades long: “If you looked at solar straight up without any of the grants, anything like that, it's probably, like, a 20, 25 year payback,” a county staff member said. County staff added that federal grants and rebates — including an EECBG (Energy Efficiency and Conservation Block Grant) allocation noted in the presentation and payments from the local utility — materially improve the project’s financial viability.

Staff described the tax-credit work as time-sensitive and partly contingent on federal rules. One presenter said the county would pursue the “elected pay” option under current IRS rules that allow local governments to receive direct payments in lieu of tax credits, while cautioning that federal program rules could change. Staff also noted procurement and supply constraints: the EECBG funding requires domestic production for some components, which narrowed the pool of eligible vendors and was given as a reason the county had to re-bid or reissue contract notices.

Committee members asked about panel lifespan, maintenance and warranties. Presenters said modern panels typically have expected useful lives in the 20–27 year range with annual degradation in output, and that the contract includes a vendor service plan. Staff acknowledged that routine maintenance matters: county-owned solar fields previously saw output decline after limited upkeep. The county said energy savings from the installations would be applied to campus energy and infrastructure funds and that Facilities and Finance meet annually to align anticipated utility bills and budget offsets.

All three contract moves — the solar installation award and the accounting-contract actions tied to federal credits — were approved by committee motion.

Staff flagged the possibility that federal program changes could affect final reimbursements or payments; the committee approved the work while noting that tax-credit recovery is not guaranteed and depends on federal program continuation and final IRS determinations.
