Common Questions
What happens at the end of the solar farm’s useful life?
At the end of the project’s operational life, the solar farm will be fully decommissioned in accordance with the approved decommissioning plan. Decommissioning includes removing all solar panels, inverters, racking systems, underground cabling, and related equipment. The land is then restored to its pre-project condition, consistent with local regulatory requirements and landowner agreements.
How long will construction last, and what can neighbors expect?
Construction timelines vary depending on project scale and conditions, but solar projects of this size typically take several months to approximately one year to complete. During this period, neighbors may notice increased vehicle and heavy equipment traffic on local roads. Atlantica coordinates with county and township authorities to minimize traffic disruption, manage construction hours responsibly, and keep the community informed of the construction schedule and any anticipated impacts.
Will the solar farm affect local agricultural operations?
Osseo Solar is being developed on privately leased agricultural land. Participating landowners receive long-term lease payments while the project is in operation. Surrounding farmland will not be disrupted by project operations, and Atlantica works closely with landowners and local stakeholders to ensure continued agricultural activity in the area where feasible. Vegetation management within the project boundary is also designed to be compatible with the rural landscape.
What impact will a solar farm have on my property value?
Multiple peer-reviewed studies have found that solar farms do not have significant long-term impacts on the property values of nearby homes or land. In many cases, the economic activity associated with a solar project—including local tax revenue and infrastructure investment—has a net positive effect on the surrounding community.
