HARRISBURG, Pa. — In a decision earlier this year, the Commonwealth Court of Pennsylvania held that agrivoltaics, commonly referred to as “solar farms,” do not constitute an agricultural use. The case, West Lampeter Solar 1, LLC v. West Lampeter Township Zoning Hearing Board, et al., 2026 WL 110932 (Pa. Cmwlth. Jan. 15, 2026) may have broader implications for Pennsylvania farmers seeking to modernize and further monetize their farming practices.
According to the U.S. Department of Energy, Solar Farms, or “Agrivoltaics,” also referred to as “dual-use solar,” is the practice where agricultural products, including crops and livestock, are located under or between solar panels. As stated by the United States Department of Agriculture, a symbiotic ‘cooling’ relationship occurs when growing crops under solar panels; plants growing under the diffused shade of photovoltaic panels are buffered from the day’s most intense rays. In the northeast, the most common form of agrivoltaics involves the integration of livestock grazing and solar panels, referred to as “solar grazing.” Sheep are commonly used to maintain grasses while decreasing fuels and emissions related to mowing. The increasing frequency of agrivoltaics is likely due to farmers’ desire to diversify their activities on their properties.
With this background, the Commonwealth Court analyzed whether the Applicant, West Lampeter 1 LLC, could develop a 25-acre agrivoltaics facility, specifically solar grazing involving sheep, on its 55-acre property. The Applicant’s property was located in West Lampeter Township’s Agricultural District and was subject to the Commonwealth’s Clean and Green Program. The Applicant sought a special exception from the Township, which limited non-agricultural uses on properties within the Agricultural District to less than 5 acres. Thus, the Zoning Hearing Board had to determine whether the proposed agrivoltaics facility was an agricultural use.
The Zoning Hearing Board ultimately determined that the proposed agrivoltaics was not Agriculture and thus denied the application. Without taking additional evidence, the trial court affirmed the Zoning Hearing Board’s holding that the photovoltaic generation of electric power, by itself, is not agriculture – citing the Clean and Green Program’s determination that solar power generation was not an agricultural use.
On appeal, the Commonwealth Court looked to the Township’s Subdivision and Land Development Ordinance’s failure to define the terms “agrivoltaics,” “agriculture,” or “agricultural activities,” and Section 107 of the Municipalities Planning Code (MPC), which defined “agricultural operation,” providing that: “…The term includes an enterprise that implements changes in production practices and procedures or types of crops, livestock, livestock products, or commodities produced consistent with practices and procedures that are normally engaged by farmers or are consistent with technological development within the agricultural industry.” See 53 P.S. §10107 (emphasis added). In light of this definition in the MPC, the Court found that there must be a connection between the technological advance and the preparation of agricultural products, finding that “Here, Applicant’s generation of electricity will not advance sheep grazing enterprise of [property owner]. Each use can be undertaken separately from the other.” Because the Applicant’s 25-acre solar farm exceeded the 5-acre limit for nonagricultural uses, the Court found the use was not permitted, holding that “agrivoltaics is not an agricultural use, and Applicant did not establish that its proposed use complied with the applicable requirements of the Zoning Ordinance for a nonagricultural use.”
With this decision, the Commonwealth Court has further limited the definition of “agriculture” which may cause a significant impact on Pennsylvania’s agricultural community. This case follows a similar pattern to that of the Pennsylvania Agritourism Activity Protection (AAPA) Act. In 2021, the AAPA was passed, limiting the definition of what constitutes “agritourism” and, in turn, broadening civil liability of certain activities on agritourism farms such as overnight accommodations, weddings, and concerts. Through both agrivoltaics and agritourism, Pennsylvania farmers who intend to diversify and modernize their properties are now limited. Farmers throughout the Commonwealth will continue to avail themselves of advancing farming technologies, which may not technically constitute “agricultural activities” under the new era of the West Lampeter Solar 1, LLC determination. The Commonwealth’s legislature should consider this decision’s impact on those farmers seeking to focus more on modern day technologies such as agrivoltaics.
