Solar Photovoltaic System Control Topology Investigation For Power Source Mismatch, Lynette O'Callaghan
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 …

First Outdoor Characterisation Of A Pv Powered Suspended Particle Device Switchable Glazing, Aritra Ghosh, Brian Norton, Aidan Duffy
Articles
Suspended particle device (SPD) switchable glazing is a candidate intervention to adaptively control solar heat gain. A high voltage low alternating current (AC) to operate a large area SPD applications, can be provided by a photovoltaic (PV) array. The first outdoor characterisation of side-by-side comparison of PV-powered SPD glazing has been conducted. Using an inverter to convert direct current (DC) power from PV to AC a 40 Wp PV device continuously powered a 0.07 W SPD glazing. High inverter power losses were found due to high PV inverter sizing ratio, inverter high self-consumption, and low solar radiation. Low sizing ratio …
