One of the problems with building solar plants on desert is that solar panels won't be able to generate enough electricity when they are covered by sand after sandstorm.
I've heard that it's not cost-effective to build solar plants on dessert, if they need cleaning frequently.
When we build solar panels, we will have to make sure how often we have to clean solar panels.
