A 1 MW solar farm requires approximately $950,000 to $1,230,000 in equipment and installation costs, excluding land acquisition. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. These benchmarks help measure progress toward goals for reducing solar electricity costs. . Utility-scale solar farms function like traditional power plants, generating electricity for wholesale markets. Electric utilities either own these facilities directly or purchase. . The focus is on ground-mounted systems larger than 5M AC, including photovoltaic (PV) standalone and PV+battery hybrid projects (smaller projects are covered in Berkeley Lab's separate U. This work has grown to include cost models for solar-plus-storage systems. However, high costs and limited efficiency kept it from widespread adoption.
