Ground-Mounted Commercial Solar Farms

Solar farms, also called ground-mounted solar arrays or solar fields, are utility-scale or community-scale solar installations built on open land rather than building rooftops. Commercial solar farms range from small community solar projects of a few hundred kW to utility-scale installations exceeding 100 MW. For businesses, municipalities, agricultural landowners, and commercial property owners with available acreage, solar farm development represents a significant income or savings opportunity.

The economics of ground-mounted solar are often more favorable than rooftop solar on a per-kW basis because installation is simpler, system design is more flexible, and optimal panel tilt can be achieved precisely. Single-axis tracking systems that follow the sun throughout the day increase production by 15-25% compared to fixed-tilt ground-mounted systems, and are standard for projects over 1 MW.

Solar Farm Models

  • On-Site Self-Consumption: Ground-mounted arrays adjacent to or near your facility, sized to meet all or most of your electricity demand, delivered via direct connection or power line to your facility
  • Utility Power Purchase Agreement: Sell electricity to the grid under a long-term utility or corporate PPA at a fixed rate, generating land lease or sale income
  • Community Solar Subscription: Develop a community solar farm whose production is subscribed to by local utility customers, generating income from subscriber contracts
  • Land Lease for Utility Developer: Lease land to a utility-scale solar developer who handles all development risk and pays annual lease income per acre for 25+ years

Land Requirements for Solar Farms

Ground-mounted solar requires approximately 5-7 acres per MW of installed capacity at typical system densities. A 1 MW community solar farm requires roughly 5-7 acres of flat to gently sloping land with good solar exposure, reasonable proximity to existing utility infrastructure, and clear title without deed restrictions prohibiting solar development. Ideal land is within 1-2 miles of existing transmission or distribution lines to minimize interconnection costs.

How much income can a solar farm generate per acre?
Land lease income for utility-scale solar typically ranges from $500-2,000 per acre per year, depending on location, solar resource, proximity to transmission, and local land markets. In strong solar markets in the Southeast and Southwest, premium land with excellent grid access can command higher rates. For self-developed community solar projects, income depends on subscriber rates and production, but fully subscribed projects in strong markets can return $1,500-4,000 per acre annually.
What permits does a commercial solar farm require?
Solar farm permitting varies significantly by state and county. Requirements typically include zoning approval or conditional use permits, state environmental review, stormwater management plans, decommissioning bonds, and utility interconnection approval. Some states have expedited solar permitting pathways for projects under a certain size. Our EPC partners manage the full permitting process and have completed solar farm projects in multiple jurisdictions.
Does a solar farm qualify for the federal ITC?
Yes. Ground-mounted commercial solar farms qualify for the Section 48E ITC at the same base 30% rate as rooftop systems, with energy community and domestic content adders available. For utility-scale projects, the Production Tax Credit (PTC) under Section 45Y may provide greater value than the ITC in some circumstances. Our advisors model both credits for projects where the choice between ITC and PTC is available.
