Re: 10,000 acres of solar panels

My price list says 120 Watt solar panel goes for $1200.00. So if noontime sunlight is 250 watts per square meter, then two of these panels would be needed. That's $2400.00 per square meter. One hectare has 10,000 square meters, and 10,000 acres is roughly 4047 hectares.

So 10,000 acres has 40,470,000 square meters > $ 97 billion cost. Then you need inverters, batteries, support frames, electrical cables, yadda yadda.

Just 10,000 acres too, a mid-size ranch in Texas. Perhaps about the size of a large commercial farm in the prairies.
