The November issue of “FotoVolt” is online. The article “Analysis of large photovoltaic system connected to the grid”, on page 10, presents the results of energy quality measurements performed on a 1 MVA photovoltaic system belonging to CPFL. The objective is to evaluate the impact of centralized photovoltaic systems in the electric grid, focusing on energy quality. The performance of the inverters under generation conditions during a typical day was also analyzed. See on page 22 the article “Advances of photovoltaic generation distributed in Brazil”, showing that the downward trajectory of PV technology prices should accelerate the growth of distributed solar photovoltaic systems in Brazil. But there are still obstacles to the development of the source and the productive chain. Read on page 26 the article “Sectioning DC circuits of PV generators on roofs”, which deals with the application of a DC remote-disconnect switch, to ensure that the intervention and rescue teams are not exposed to live parts. This issue brings also the update “PV inverters” buyers’ guide.
