The cost of solar production is highly dependent on geography, and in some places, like California, Nevada or Arizona deserts cheap land and good weather allows for massive economies of scale https://gigaom.com/2015/01/20/a-special-report-the-rise-of-a...

Countries with sunny deserts do get an economic edge on this one though compared to overcast, densely populated countries http://www.bloomberg.com/news/articles/2015-01-15/acwa-power...

But there's no turning back - once the newcomer into space gets a massive economic advantage by having access to cheap energy, they attract industries that are relying on cheap energy, and soon those market participants overrun their competitors whose cost structure includes higher energy costs.
