How many acres do you need for solar panels? Acres per MW, sourced
General information, not a substitute for the advice of an attorney.
Short answer: utility-scale solar uses roughly 4 to 7 acres per megawatt. Small projects can fit on 10 to 25 acres, but most Texas grid-scale projects need hundreds of acres. Battery storage needs far less land.
Solar
Utility-scale solar typically uses roughly 4 to 7 acres per megawatt (Penn State Extension; University of Wisconsin Extension). Lawrence Berkeley National Laboratory found U.S. plants built in 2019 used a median of about 5.6 acres per megawatt (AC) with tracking panels, which by 2019 outnumbered fixed-tilt plants about two to one nationally, and about 3.6 with fixed panels (Berkeley Lab).
Extension guides put the practical minimum at roughly 10 to 25 acres for small projects, depending on the guide, with larger parcels more attractive (Penn State Extension; University of Missouri Extension). Texas grid-scale projects are much bigger: the median solar project in ERCOT's September 2026 interconnection report is about 200 megawatts, which at Berkeley Lab's median densities (3.6 to 5.6 acres per megawatt) means roughly 700 to 1,100 acres; at 4 to 7 acres per megawatt, 800 to 1,400 (our count from ERCOT's interconnection status report). Usable acres are what counts: wetlands, flood zones, pipelines, steep ground, and setbacks come off the top.
Battery storage
Battery sites are much smaller. Indiana's state energy office estimates about 0.03 to 0.1 acres per megawatt, so a 100 MW site needs roughly 3 to 10 acres (Indiana Office of Energy Development). One land-leasing firm describes typical battery projects as 40 acres or less (Trigen), and one leasing marketplace says the most important factor is whether a substation is on or near the property (SolarLandLease).
Location beats size
A smaller tract next to a strong power line can be worth more to a developer than a large one far from the grid. See how close to power lines your land needs to be.
