I wonder how long it takes them to break even on these things lol?
According to some rough calculations, about 5 years:
Higher-end SunPower panels go for ~$0.90 per watt of capacity (cheaper brands are cheaper... I don't know what brand Apple is using). For 20MW, that would be about $18 million for the panels. Add $3 million for the land and you get $21 million. To round things out, we can add another $4 million for installation, maintenance, etc, for a total of $25 million.
Electricity is pretty cheap in NC, about $0.12 per kwh. Apple expects to generate 42 kwh per year, so that's roughly $5 million per year in savings. Assuming the $25 million total cost for the array, Apple will break even after about 5 years.
Of course, if Apple uses cheaper panels, gets preferential electricity rates, or if the construction/maintenance costs differ from what I assumed, the payback period would either be pushed out or occur sooner.
Environmentalists have been demanding "renewable energy" for a long time.
Solar power has been touted as wonderful and desirable for a long time.
Well, there it is. That's what solar strip-mining looks like.![]()
With solar, you only have to clear a finite area of land once (if the land actually needs clearing). With coal, you have to blow up additional mountains every year.
