Solar Photovoltaic System Control Topology Investigation For Power Source Mismatch, Lynette O'Callaghan
Conference papers
An investigation into solar photovoltaic (PV) system control topology selection, when partial shade is anticipated in the solar array, is presented. As available area is maximised in Building Integrated PV (BIPV) systems, shading is an inevitable consequence. The presence of partial shading in a PV array leads to multiple power peaks in the power-voltage curve, due to bypass diode sections being triggered, and an increase in module mismatch losses in the array. A building energy design software, Integrated Environmental Solutions, is used to determine the shadowed area on PV modules throughout the year, incorporating the PV system location and geometrical …

Multifunctional glazing is a combination of various glazing systems and can comprise permutations of vacuum glazing, aerogel glazing, PV double glazing and Electrochromic (EC) glazing. It controls solar heat gain, improves thermal conductivity and can generate small scale electricity, in a variety of climates. The objective of this research is to investigate the switching voltage of multifunctional glazing, with respect to orientation, time of day and temperature of the system. We report a relation between temperature and voltage required for the switching condition.
