There's lots of creative accounting behind the recent headlines on the competitiveness of solar. Without an efficient means to store solar power, you can't run an electricity grid off solar alone, and you need a more reliable baseload. Not only that, but the base load stations need to be able to raise and lower their own power generation (gas is best for this) to accommodate the sudden spike in solar energy supply.
