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
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.
