The oldest utility-scale solar plant in the county came online in 2024.[1] Solar lease agreements can last 20 to 30 years.[2] The newest came online in 2025.[1] Federal guidance for farmers describes solar lease payments as typically structured as a fixed annual or monthly fee per acre, or as a percentage of the energy generated by the solar panels.[3] Rent during the operations period will likely include an inflation adjustment, which may be tied to a measure like the Consumer Price Index or set at a fixed rate.[4]
What Buckhead buys depends on the deal, and Buckhead tells the seller up front which interest it is offering to buy — for example, the payments for the rest of the current lease term, a term easement, or a longer-term interest. Solar rent is paid period by period, the operations period may last 20 years or more, and renewals are at the developer's option.[4] The land can be converted back to agricultural uses at the end of the installation's operational life.[3]
