I know next to nothing about solar power but was curious about some of the numbers posted here so I did some internet searching. I am assuming numbers vary a lot by location, but it seems technology is improving in regards to output per acre. It seems as of 2 years ago, the most common number was 4 acres per MW. I did see one report that said 2.5 acres, but I didn't find any other reports to back that up. IF the 4 acre number is accurate that would mean an output of 1500 MW on a 6000 acre parcel.
It varies, depending on the number of days of full sun, versus days of cloudiness. Today's solar panels can produce power even on cloudy days, but it won't be to full capacity.
Most solar farms are restricted not by how much the total farm can produce, but by how much spare capacity there is on the transmission lines nearby.
This one, (there will actually be 3 different farms in the immediate area) has spare capacity of about 1800 MW in the transmission lines. They are feeding DFW.
Invenergy approached Prairiland ISD last week with a plan to build a 300- to 500-megawatt solar farm on 6,500 leased acres near Cunningham in southeastern Lamar County. Cost of the Samson Solar Energy Center is between $350 million to $450 million.
In August, the district gave preliminary approval to German-based Alpin Sun to build a 250-megawatt farm on 1,867 acres, also near Cunningham. With a cost of $240 million, the Impact Solar project has a value limitation agreement with Prairiland ISD awaiting approval with the Texas Comptroller's Office.
Alpin Sun also plans a 100-megawatt solar farm on 968 acres in Fannin County, according to the firm's value limitation application, available online with the Texas Comptroller's Office. The Impact Solar farm comes with a cost of $96 million.
