Abstract

A multi-parametric evaluation of a photovoltaic (PV) solar wall device was performed. The PV solar wall device was built with a pair of PV modules, a ventilated air cavity and an insulating back panel of plywood board filled with polystyrene installed in an outdoor test-room. The full scale outdoor test-room experimental facility for a PV solar wall device was set up at Concordia University, Montreal, Quebec, Canada. The experiments were conducted for obtaining currents, voltages, temperatures, air velocities, sensible heat capacity and thermal storage capacity of a PV solar wall device with active ventilation through an outdoor room. The effect of heat conduction and radiation exchange was considered in evaluating a PV solar wall device through an energy analysis model. Photovoltaic amplification was attained with power output from a potentiometer through rotation of its circular knob. A PV solar wall device was further analyzed for its electrical parameters as Resistance-Capacitance (RC) electrical analog circuit. The effect of inductive and capacitive heating losses was considered in evaluating electrical characteristics of a PV solar wall device exposed to solar radiation. A definition, measurement expression and unit for an electrical noise were also coined.
