It remains to be said where the resources will come from to install these dozens of solar plants.
Although the system pays for itself in 4-5 years, this involves a lot of public resources for the projects and for the bidding processes for the implementation and maintenance of the plants.
For certain city halls that can barely manage to pay their employees, this could be a shot in the foot.
