What Midwest communities should ask before productive farmland becomes an energy site
Drive almost any rural road in northern Illinois and you may see a new kind of crop: rows of dark solar panels on fields that recently grew corn or soybeans. Their rapid arrival raises a difficult question for McHenry County: How do we welcome cleaner energy while remaining faithful stewards of some of the nation’s most productive agricultural land?
This need not be a choice between being “for” or “against” solar. Photovoltaic panels generate electricity without air pollution or greenhouse-gas emissions at the site. They can provide dependable lease income, broaden the tax base and reduce reliance on fossil fuels. But output varies with daylight, season and weather, so a dependable grid also needs transmission, storage and other sources of power. The cost-benefit discussion must consider the whole system—not merely the panels inside a fence.
Land is part of that cost. Ground-mounted solar commonly requires roughly five to seven acres per megawatt. Nationally, substantial growth could be accommodated through rooftops, parking areas, brownfields, landfills and less-productive acreage. Yet national percentages obscure local consequences: concentrating development in a county with exceptional soils is a different proposition.
What Illinois law changed
Illinois law sharply limits county regulation of commercial solar facilities. Counties must hold a public hearing, allow comment and permit interested parties to present evidence. Yet a proposal that meets the state framework, a compliant county ordinance and other applicable laws “shall be approved.” Counties also may not prohibit solar in districts allowing agricultural or industrial uses or impose more restrictive standards.
Public opinion therefore has a voice, but not a general veto. The most useful participation is specific and evidence-based: Does the plan protect drainage and neighboring farms? Are screening and perennial cover adequate? How will soil, roads and habitat be monitored and restored?
Important local levers remain. Counties may require farmland drainage plans, certain vegetative screening, perennial ground cover, natural-resource review and adherence to some state ecological recommendations. These provisions make the quality of project design—not simply the approval vote—a legitimate focus of public scrutiny.
McHenry County residents push back
Local resistance is not new. In April 2018, residents packed a zoning hearing over a proposed 35-acre development on unincorporated farmland. Neighbors and nearby officials argued that it belonged on a brownfield or industrial site, while also raising concerns about glare, taxes, property values and possible health effects. The turnout was unmistakable, though not every claim carried equal scientific support.
After Illinois narrowed county authority in 2023, McHenry County approved a dozen solar farms but added conditions responding to watershed, farmland and pollinator concerns. A developer sued, arguing that the conditions exceeded state law. In January 2024, the County Board voted 11–6 to repeal them.
The conflict intensified in 2025. Residents repeatedly filled the County Board room to oppose Water Locust Solar near Ringwood and Spring Grove roads outside Johnsburg, many wearing “Protect Johnsburg—Deny Water Locust Solar” stickers. They cited productive farmland, groundwater, environmental effects, rural character and perceived health risks. One neighbor stressed that she supported solar, but not on highly productive land at the village boundary.
In December, the board rejected Water Locust 13–4 and denied three other proposals; Pebble Solar near McHenry lost 16–1 amid questions about woodlands and wetlands. Developers went to court. In July 2026, judges directed approval of several denied projects, and the board approved five solar farms under court orders. Public concern is not proof—claims require competent evidence—but this sequence explains why many residents feel their role has been reduced from consent to mitigation.
It also reveals a larger civic tension. Land-use decisions are experienced locally—in a changed view, a neighboring drainage system or the loss of a familiar field—while much of the governing policy is now determined in Springfield. A durable energy transition will need public trust as well as legal compliance.
A solar farm is temporary—if we make it so
Most photovoltaic systems are expected to operate for 25 to 35 years. An owner may then re-power the site with newer equipment or decommission it. A superior technology will not automatically restore the field: existing transmission access may keep the site attractive for energy production. Its future will depend on economics, ownership, lease terms and obligations established decades earlier.
Illinois requires an Agricultural Impact Mitigation Agreement calling for a professional deconstruction plan, equipment removal and financial assurance. Funding phases from 10 percent after the first year to 100 percent by year eleven, with an updated estimate in year ten and possible county reviews every five years thereafter.
These are meaningful protections, not a magic reset button. Some deeply buried cable may remain, and agricultural value resides in soil structure, organic matter, contours and drainage. Heavy traffic can compact soil; grading can redirect water; damaged tile can affect land beyond the project. Restoration on paper may not equal restored productivity.
The ecosystem ledger
A field is more than a production surface. Healthy soil stores and filters water, cycles nutrients and supports living organisms. Construction can impair those functions through compaction, grading, bare soil, runoff, invasive weeds and drainage damage. Sediment and altered water flow may reach neighboring fields, wetlands and streams. Conventional fencing can also fragment habitat and impede larger wildlife.
What the project replaces matters. Converting prairie, a wetland buffer, woodland or a wildlife corridor is not equivalent to converting an intensively managed row-crop field. Good siting avoids sensitive habitat and preserves connected travel corridors; wildlife-permeable fencing can help where security allows.
There can also be gains. Diverse, locally adapted perennial vegetation may reduce erosion and chemical use, improve infiltration, rebuild organic matter and provide habitat for pollinators and birds. Sheep grazing or other agrivoltaics can keep land in agricultural use and diversify farm income. But repeatedly mowed turf—or an impressive seed list that never becomes established—is not functioning habitat. Benefits depend on design, seed selection, management, monitoring and accountability over the full life of the project.
A better-looking—and better-functioning—edge
Illinois law already allows counties to require certain vegetative screening between solar facilities and nonparticipating residences, although it must be commercially reasonable and may not reduce energy output. Within those limits—or through stronger state standards—approvals could require shelterbelts along visible boundaries: layered native grasses, shrubs and trees that screen fencing and panels while slowing wind, intercepting rainfall, reducing erosion and runoff, and providing habitat. Plantings should be wide enough to work, maintained for the project’s life and independently inspected. Species and placement must respect drainage, utility access and panel shading, using lower shrubs where necessary and taller trees where distance and orientation permit.
Planning now for an unknown future
End-of-life responsibility extends beyond soil. Panels contain mostly recoverable materials, but recycling is not always the cheapest option and some discarded panels may require hazardous-waste handling. Every project should maintain an updated plan for reuse, recycling and disposal.
The wisest path is neither to reject solar nor treat every acre as interchangeable. Policy should favor roofs, parking lots, disturbed ground and less-productive land; protect soil and drainage from construction onward; require durable landscaping and transparent monitoring; and keep decommissioning funding current through ownership changes.
The sunlight harvested for thirty years has value. So does soil that may feed people for centuries. Today’s energy solution must not become tomorrow’s abandoned infrastructure, restoration bill or diminished field. Progress and stewardship can occupy the same ground—but only if we plan for both.
