VA Engenharia conducts studies and implementation of photovoltaic systems to ensure the consumer a distributed generation with clean energy, in addition to a more sustainable energy matrix, better use of resources and greater energy efficiency in enterprises, thus contributing to a more sustainable planet. The photovoltaic system is part of the Distributed Generation according to RN 482/2012 (normative resolution of ANEEL) in which is the energy produced by a source located in the own consumer. By ANEEL the energy generation is classified as follows:
- Distributed Microgeneration: Systems for the generation of renewable energy or qualified cogeneration connected to the grid with power up to 75 kW;
- Distributed Minigeneration: Systems for generating renewable energy or qualified cogeneration connected to the grid with a power of more than 75 kW and less than 5 MW.
With its implementation, all the energy that the consumer-generator produces is used by himself and, after deducting his own consumption, the surplus is returned to the distributor. All the energy that is "left over" and returned is credited to the consumer-generator's account, thereby making available a positive balance in energy credit, in its next bill, with a period of up to 60 months for use.
