Sorry, that's Texas farmland "acres". An "acre" is a medieval unit of measure defined as one "chain" by one "furlong", the area a single man can plow in a day with a team of oxen. Although people have been plowing with horses since the 12th century, the "acre" is still in use in Texas, where it is roughly equivalent to 0.405 hectares (4050m² in SI units). In Texas, latitude ≈30°, it amounts to roughly a megawatt of solar energy (3 megawatts peak) before accounting for panel inefficiency.
Also when I said "US$0.10/Wp" I was wrong. I'm in the lazy habit of rounding US$1 = €1, but that's a significant error now. The correct price of €0.100/Wp for mainstream solar modules is more accurately US$0.117/Wp.

1) People plowed with oxen well into the 20th century. Most places, only fancy people could afford horses at least into the 17th-18th century. So not so totally-medieval.
2) The acre is used in all kinds of backwards (Anglophone) places, not only Texas. All of the USA for starters, probably Australia, maybe the UK... Heck, I remember my elders using the (roughly) corresponding "tunnland" in daily conversation in Sweden as late as the 1970s. (But yeah, they were really rather elderly.)
3) Aren't you the guy who should call that "the 0012th century"? (Sorry if I'm getting you mixed up with someone else.)
