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 1.12 between PV and inverter offered less power losses from inverter output. PV powered SPD is a promising self-powered switchable solar heat gain control glazing.
