Indeed, but also with this amount of solar, free money would need to be issued, to represent the product being added to economy which is the Joules put into all things. Otherwise money will devalue even further, since it would be not representing actual product being put into use. That done, and given to all people, then finally we see how it converts to wealth for all people, to buy fuel or whatever.
A further technical consequence is that by scaling up the solar energy a little further, using some of this stimulus, would enable all batteries to be replaced by fuel cells, then all domestic transportation fueled from hydrogen continuously produced by all communities. All existing evs are theoretically aftermarket convertible from ev to hev, and all internal combustion engines are convertible to burn hydrogen. The financial reward received by all people at the rate of a proportion of the number of Joules solar energy received and put to use, would be a significant income, removing the need for anyone to work at anything other than voluntary, and probably most crime.
It would also cut all bullshit industrty currently dependent on the fossil fuels industry, such as taxing pollution, and decarbonisation, they would no longer be required, removing more of the industrial burden from the grid, maybe even rendering the grid itself mostly redundant if the bigger industries also go fully solar powered.
The is the real revolution waiting to happen, it seems to me.
