Energy payback is now as little as 0.5 years for utility scale PV. Not counting any open source integrated design improvements. To take it to 0.25 year energy payback time (UMG gets us 30% lower energy already), which is impossible, and thus a perfect project for OSE to take on.
But if we start with 1MW of PV power, and use 1/2 of that for producing more PV - then the time to breed 20TW, starting from 1 MW - is :
T_p is payback time. f = reinvestment fraction. So real impact comes from payback time shortening, and reinvestment expansion.
If we start with 1 MW, and reinvest 50% of energy back into PV manufacturing as a 'solar breeder reactor' - then we have 17 years to replace all energy on earth.
