Solar Energy in Brazil´s northeast Dear Folks, my friends and I decided to start our own company that will be in charge of develop projects and installation of photovoltaic (PV) solar energy systems in Brazil´s northeast region. In this region we have a lot of sunlight during the day and that is very important to obtain electrical energy using this system. This kind of system isn't popular in this region nowadays, but the potential to do it here is enormous. People pay expensive bills for the energy supplied by the Electrical companies and a PV solar system should be an alternative to have a cheaper bill and to use a renewable energy source. Depending on the PV solar system installed, you should even sell the surplus energy that you produced to the electrical company.
