> Solar panels are already good enough that they are used in developed countries such as USA and UK. Are they perfect? No, they cost too much, and they don't generate enough electricity, but they are used none-the-less.
Subsidy and vanity explain a lot of economic activity.
Plus, energy costs are not very uniform. It's much easier/cheaper to get power to the next house in a suburb than it is to get power to a freeway sign 10 miles from the nearest town. That's why solar is cost effective in some situations even when it doesn't make sense in general.
