Is solar energy viable in São Paulo?

 Friends and neighbors always ask me this question.

Recently, for one of my neighbors, I informed, on the portal specialized in residential solar systems, (Portal Solar) that the local concessionaire charges R$ 400/month (about USD 70) of electricity.

The simulator presented the following results:

* Specified power of solar equipment is 5.1 kW
* The investment required in the installed system is R$ 30,000
* The monthly savings it will generate is R$ 400/month
* The financing for payment in 84 months (7 years) is R$ 730/month

Thus, the solar system will have a monthly amortization cost that is almost double the savings it makes.

This means that the decision to deploy a solar system would be especially associated with a passion for the solution and not for the cost reduction.

1 USD = R$ 5.6
