The economics of that when you have to include storage is different than places with almost no cloudy weather. There isn't much interest to invest in solar + storage solutions without subsidizes.

Solar/wind in combination with natural gas is very profitable in the UK as long the natural gas is cheap enough. Right now that is not the case so the cost of the energy grid in UK is extremely high, and much higher than in solar heavy countries located next to deserts that don't need to use natural gas to cover all those rainy and snowy days.
