This paper presents the development of an automated experimental platform that has the ability to collect photovoltaic energy generation data as well as factors that influence the generation of energy by photovoltaic panels. The system has the capability to analyze different photovoltaic systems, being able to compare them in different conditions or to compare different systems. The energy generated by photovoltaic systems is controlled by electronic loads. Both voltage and current are measured by Hall Effect sensors, which guarantee galvanic isolation between the power and the instrumentation systems. The platform also has the capacity to perform temperature readings of the photovoltaic modules and solar radiation, which are factors of influence in the generation of photovoltaic energy. The sensor signals are conditioned and read by a data acquisition device (DAQ) that sends this data to a personal computer. In the computer was developed a supervisory program for reading and storing the information. The platform has the ability to test and analyze either photovoltaic panels individually or multiple panels and even photovoltaic systems with direct current (DC /DC) converters. The automatically acquisition of data allows the registration at short intervals of time (every second) during long periods of measurement (days), without the need for human intervention. Therefore, it guarantees flexible tests with reliability and high resolution. |
