That's rather the point; tech breakthroughs happen when there is a drive to achieve something, increased demand for solar causes that pressure to strive and thus increases the likelihood of innovation. The more panels that are built, the better we get at building them, innovate, repeat.

Except this is not a demand for solar, just for cheap energy - it just happens to be that solar is cheap sometimes.

If solar happens to not be cheap, very sustained, increased demand for non-solar sources increases the likelihood of non-solar success.

Solar is already the cheapest source of energy ($0.03 to $0.06 per kilowatt-hour), and it's getting cheaper by the day.
