Abstract
This thesis describes the implementation of an experimental setup to capture the maximum power point data of photovoltaic (PV) modules. The experimental setup operated for a one and a half year period, and the data collected is analyzed in this paper to determine if it is possible to maximize power conversion by varying the step and interval parameters of maximum power point tracking (MPPT) algorithms for each day. For each day, short circuit current data is collected at a high frequency (2 kHz) and full sweeps of the PV IV curve is done about every three seconds. The large amounts of data are broken down and each sweep is parameterized and then the perturb and observe algorithm is run over the data for different interval and step parameter sets. The conclusion is that it is possible to maximize the power conversion over the whole year, though further analysis is currently needed to ascertain to what extent this is possible.
