Geração distribuída de energia elétrica e panorama fotovoltaico brasileiro e português

This work presents a study on the design of a photovoltaic system connected to the grid.It discussed the main characteristics of the solar cell which is the basic component for the manufacture of solar modulethe main components of the photovoltaic system and the steps of the photovoltaic and electrical design of the system, ranging from the choice of the photovoltaic module to the dimensioning of the components of the electrical installation.In addition to the technical design, this work contains a complete comparative analysis of the current situation of photovoltaic generation distributed in Brazil and Portugal, through incentive programs to energy use as well as current legislation in both countries

Proposta de controlador de carga com MPPT utilizando LabVIEW

This paper presents one proposal of the energy management's model system using photovoltaic panels. The module proposed seeks to monitor photovoltaic panels, which have intermittency in power generation caused by environmental or load conditions, in order to control the coupling between the panel and the load - through the charge controller, of aiming that the panel's operation will be always on the maximum power transfer point as possible. For this, it used the maximum power point tracking technique - MPPT, implemented in LabVIEW software, also utilizing the data acquisition card NI myDAQ. In addition, it was implemented the controller access remote module, from the sharing of network data, so the panels performance can be through a tablet, monitored and controlled with no need for direct contact with the Supervisory server

Utilização de painéis solares fotovoltaicos no segmento residencial

In order to diversify the global and national energy matrix and reduce harmful impacts on the environment caused by the emission of polluting gases into the atmosphere, the use of clean and renewable energy sources is presented as a good alternative. This work discusses the use of photovoltaic solar energy, a source that presents such characteristics. The photovoltaic system under study is the type distributed connected to the grid, in the residential segment. It is informed of its use in the global and national levels. They are also present their characteristics, electrical and electronic circuits that make up the equipment required for its operation and the design of a system to be installed in a residence
