<meta http-equiv="x-dns-prefetch-control" content="off">It will depend on the technology of the modules, too--whether you're using monocrystalline, poly, or thin-film. I recently spec'ed a thin-film design which worked out to 150 kW per acre. With more efficient modules you could be 50% better, so your 5 acre/MW number is reasonable.<div>
<br></div><div>It also will depend on where you are building the plant. At higher latitudes, you might want the array to have a greater tilt, which probably means you will space the rows out more to minimize inter-row shading.</div>

is the approximate land usage of a ground array in acre/MW. I have estimated
around 5 acre/MW but I'm really not sure if I am way high or low.
