The 7x more claim depends largely on the fact that the space base solar power system would have 3-5x higher capacity factor compared to typical land based solar systems. Curiously, the space based solar idea doesn't offer significant area savings on the planet due to the very large area required for the terrestrial absorber. The real question therefore is whether this can compete with land based solar with storage and HVDC such as solar thermal with thermal storage or PV farms with pumped hydro. Once properly sited, a solar farm with storage is quite dependable and one can use biogas for occasional weeks of prolonged clouds. It seems to me that such a combination would be much more practical than space solar power. No, its less than a factor of 2 increase in power density.

But checking the available spectrum and the energy, seven is times is a valid but optimal multiplier. The atmosphere and the magnetosphere are significant barriers. Interesting point from Russ.

The above statement is new to me - not even close to correct is it? The project got regulatory OK? The headline is totally smoke - they just said that if the power was competitive PG&E could buy it. İ hope PG&E is not being allowed to invest any funds whatsoever in this until it is a bit father along than just dreams! ‘Space based solar also could collect as much as 7 times more power per area unit as the collector isn’t blocked by the atmosphere.’
