The SP75's are 16 for $5k. If they keep the SQ80's priced the same, then your best possible under ideal circumstances power cost would be: 16*80*12 hours = 15.4 kwh per day

Times 365 (must be good weather somewhere) days = 553kwh per year or 110.6 kwh per Dollar (about $.01 per kwh).

Which would be cheap enough if you got that much peak Sunlight. With no rain. No clouds.

Somebody out in Arizona is going to love these things. Somebody in London is never even going to get to use them.

I doubt the average power is even 30% of the peak number.

If you're off the grid, wind and solar aren't unreasonable options.

They are not solutions for an advancing civilization. Both transmission and storage are nightmares.
