A 2.5 kW peak, CPV demonstrator and testing facility has been deployed in Ottawa, Canada's northern climate (45.45°N, 75.62°W). In order to analyze the most important influences on overall system performance, the demonstrator was fully instrumented and a versatile system model was developed. Three inputs are currently evaluated in the model: spectral variation throughout the day, an optical transfer function (OTF) of the concentrating optics and the solar cell external quantum efficiency (EQE). The model has shown that the introduction of an OTF that absorbs/scatters light across the spectrum and cuts off wavelengths below 400 nm shifts the entire system efficiency curve down and its peaks to lower air mass (AM) values.
