Increasing public policy support for solar energy production in the United States provides opportunities for farms to expand into vegetative management services for array operators and remediates some concerns associated with the loss of farmland. A farmer-owned solar grazing cooperative is examined to understand the potential for transaction cost savings of collective action. A needs assessment survey to current and prospective sheep farmers demonstrates sufficient interest to explore a cooperative business model for coordination across farms and solar sites. A detailed analysis of the costs associated with contract negotiation, mobilization, and shepherding services identifies minimum lease payment rates required from solar array operators for financial feasibility. Profit margins and returns on investment suggest competitive returns to alternative investment opportunities and where cooperative returns are at or nearly twice as large as those from individual action, but with results highly sensitive to lease payment rates secured.
