And 1300 sf is less than the roof area of a normal house.
And besides I saw that a guy is not building a factory to make the cells that can actually be used as shingles on the roof and will be much cheaper than what we have now.
And you are right it is current not voltage that counts. but what I would really like to know has more to do with chemistry than electricity. And that is how much energy does it take to separate Hydrogen from watter, because a fuel cell could deliver the needed power when it is needed and the Hydrogen can be made when the sun shines.

But Edison argued, and I think he may have had something there that AC was dangerous because of the induced voltage from the alternating current.
And His power plants were all local so there was no problem with transmission losses.
EVery thing that can be done with an AC motor can be done with a DC motor and in face in some cases it is better. and 100 volts AC will deliver the same power as 100 volts DC. The space station operates quiet well on DC power.
