It's a great point. Even in my spot in northern California this winter, it's been so cloudy this year, I can't imaging an all solar+storage grid would have worked out well this year. In this case having electricity that costs 45% more when it's cloudy is a lot better than none at all. Actually this gave me an idea, it would be really neat to have an comprehensive simulator of power grids that incorporated weather, demand spikes etc. to play around with different energy source mix to get an idea of what actually works and when it fails as well as total cost, environmental impact etc.
