No, the real concern is average output, not the "HURR DURR WHAT WHEN THERE ISN'T ANY SUN OUT". There are cases for solar and wind too (I mean denmark and the netherlands pull it off), but you need to balance your infrastructure. There is no one size fits all solution (except nuclear, which really is that, but it requires a real investment into expensive infrastructure and thus usually nationalised ownership or at least subsidies, no private energy startup company can afford it).
