Solar: crossroads
The consumer of residential energy, who evaluates a solar solution is faced with a challenge in Brazil..
What will make more sense?
1) Invest to have solar energy
or
2°) Migrate to the free market
Investment is an alternative that requires a period measured in many years to make the return viable, especially if real remuneration is required (inflation + compounded interests).
Migration is just a change in the way you contract energy. It does not depend on investments. But you have to wait for it to be available.
Summary: it is the horizon that you use that defines what will be most advantageous. If you can afford to wait 3 or 4 years, migration to the free market should be much more attractive because savings should be significant WITHOUT investments.
