- Abstract
Despite presenting a considerable potential for photovoltaic (PV) solar energy conversion, many times larger than the country’s current and future energy needs, PV generation still plays a negligible role in the Brazilian energy mix, lacking a proper market, legislation and incentives to make use of this benign energy source. The still high capital costs involved in PV project implementation, associated with the perception that grid-connected PV is only suitable for developed countries, are the typical arguments used to justify the lack ofinterest in PV as an energy alternative for urban grid support in metropolitan areas. It is possible to demonstrate that in the near future, the price of energy generated by a residential consumer with a roof-mounted, grid-connected PV system can be lower than the corresponding residential tariff paid by this electricity consumer to the local distribution utility. It is then argued that, from this moment on, this consumer has the right to decide for the least-cost alternative, and that the Brazilian legislation has the duty of enabling this option. In this article we present the situation in Brazil regarding the application of grid-connected PV, and we demonstrate the potential benefits of this energy generation technology. We also summarize the current legislation and commercialization aspects related to grid-connected PV installations. Furthermore, the paper presents bottlenecks to a more widespread use of PV generation in the Brazilian energy mix, and identifies the need for the creation of an incentive mechanism that can assist in bridging the gap to grid parity, which is expected to take place in Brazil in the coming decade.
