Ready for solar panels on your neighbor's lawn? Waukee is a step closer to making it happen.
The city is considering allowing ground-mounted residential solar energy systems — but only at homes on large plots of land. Sound Insulation
While the change wouldn't allow the same flexibility other homeowners in the Des Moines metro have to decide what kinds of solar panels work best for their homes, it still would be a first for Waukee and part of a growing trend across Iowa in homeowners who choose solar energy.
For the owner of what could be the first ground-mounted residential solar panels in Waukee, it's about lowering his electric bill.
Ron Grubb has lived on 5 acres in the city for about 25 years. He has a large home with a pool and a pool house that run up his electric bill.
Grubb thinks turning to solar panels is the solution. But while Waukee allows roof-mounted panels, Grubb, a homebuilder and owner of Jerry's Homes, said he "would never encourage anybody to drill any holes in their roof."
So he went to the city to request a change in its code. The Waukee City Council will consider an ordinance Monday to allow ground-mounted solar panels in backyards in three zoning districts: agricultural land intended for future urban development, agricultural areas tabbed for large-lot residential development and single-family residential areas.
But not all homes would be eligible because the code would require ground-mounted solar panels on larger lots, according to Andy Kass, the city's community development director.
"The minimum required acreage is 2 acres, and there aren’t that many single-family lots that large in our community," Kass said.
Allowing both options gives homeowners more flexibility in choosing alternative energy sources, said Kerri Johannsen, energy program director for the Iowa Environmental Council, an environmental advocacy nonprofit.
Some roofs may be too shaded, have an odd shape or are not structurally sound for panels, she said.
"Allowing ground-mounted systems is a more flexible option, and definitely restricting to roof mount only can cause people to lose out," Johannsen said.

Most cities in the Des Moines metro allow for both ground-mounted and roof-mounted solar panels on homes, according to city officials, though laws vary:
There also may be specific rules of homeowners' associations.
Ground-mounted systems are not allowed in most residential areas of Clive, according to city spokesperson and assistant city manager Pete De Kock. A special use permit is required for ground-mounted solar panels where they are allowed in commercial and some residential areas, he said.
Most new installation of solar energy systems in Iowa through last year continued to be driven by utility companies, according to the Solar Energy Industries Association.
But the power-generating capacity added in the state by new residential solar panel installation has been growing since 2018. In 2022, home panels surpassed the capacity added by panels newly installed on commercial properties, according to the association.
Prices for residential installation of an average 5-kilowatt or 6-kilowatt system can run up to $20,000 or more, according to various industry and news sources.
Scott Prohaska, executive vice president of 1 Source Solar — the Ankeny-based company Grubb is working with for his home — said Grubb's prospective 28-kilowatt system could cost between $68,000 and $70,000, before deducting a federal tax credit.
The federal government last year extended a tax credit for home solar installation through December 2034 and increased the credit to repay 30% of installation costs.
Johannsen said the federal tax credit helped contribute to a jump in solar panel installation between 2021 and 2022.
But there's also been a "big uptick" in Iowa that started in 2020 when Iowa passed a law that allows for net metering — when any excess generated power is sent back to the grid and credited to the customer. MidAmerican Energy Co. and Alliant Energy both provide net metering.
Johannsen said net metering and high electric rates make solar energy more economical because it means faster payback on the cost of a system.
"This law provided certainty that policy would be stable and favorable for customer-owned solar in Iowa for years into the future," she said.
