Abstract/Summary:


As a rule of thumb, PV power plants arrays are planned and installed with a fixed optimal position to collect as much sunlight as possible throughout the year. In southern and northern latitudes this means finding the best configuration for summer seasons, which leads to a typical midday peak-­shaped power curve. On the other hand, in order to reshape the power supply curve, assuming Solar PV as part of the supply of a base daily load, the solar tracking option involves not only a higher initial investment but also higher maintenance costs, not even taking into account the power drawn from each array multi-­axis servo-­drive. For research, energy savings and carbon reduction levels purposes, a 1 MW peak Grid-­Connected Solar Power Plant in a “Static Solar-­Tracking Configuration (SSTC)” was commissioned in July 2014 at the North Campus of the Karlsruhe Institute of Technology (KIT) in Karlsruhe, Germany. A total of 102 fixed solar arrays with different PV modules available on the international market, with nine different orientation angles, each one with more than 3 different tilt angle setups and different individual market available power converters, which are monitored independently to assess the everyday performance of each array, feed all the instantaneous generated power as part of the base load supply of the KIT facilities. This research focuses on analysing the effects of the SSTC designing approach on the performance of the PV Power Plant through the different day-­to-­day scenarios involving the randomness of weather conditions, which affect solar irradiance.
