I note the use of passive voice ("...people are not encouraged...") and that is the root of the problem.

Just who is it that is supposed to encourage these people?

The electric company? They're in the business of selling electricity, not buying it.

The solar panel manufacturers? Why would they want to sell their products at a loss?

The government? Here in Mexico, the government IS the power company.

Where I live, solar seems like a marvelous idea, until it's time to pay for it. Solar is expensive, particularly in relative terms. There is no way that the majority of people here can put two year's gross income on their roof when many of them can barely put tortillas y frijoles on the table every day.

From the point of view of benefiting the ecology and reducing consumption, CFE (the Mexican power company) does indeed encourage low usage through their punitive rates for high consumption - something I am in favor of. (The punitive rates, that is, not the high consumption )
