This work aims to experimentally evaluate the string, microinverter and d.c.-d.c. converter technologies, in order to contribute to scientific knowledge construction in applications of the different interconnection architectures of photovoltaic generators to the conventional electric grid. For this, were used different systems installed at GEDAE’s laboratory (UFPA), located in northern region of the country. It was compared the performances according to the information from different data acquisition mechanisms available in the laboratory. In face of some of these data acquisition mechanisms provide only the value of energy accumulated throughout the day, a focus was given on the overall operation of the different systems analyzed. However, in those systems which greater operational details were monitored, either by the equipment's own acquisition system or already existing equipment in the laboratory (Fluke Digital Storage Oscilloscope, Digital Power Meter, etc.), important point analyzes with more detailed operation of the system were performed. The obtained results show that the d.c.-d.c. converters system presented superior performance to the other monitored systems. However, it has been found the occurrence of problems due to the pairing process of the d.c.-d.c. power converters in the operation of such systems that remain until now.
