Abstract

A study is commencing on relating the spectral responsivity of reference cells in the field to changing spectral distribution during the day. Initial results indicate that measurements of the incident spectral distribution can match relative results of reference cell measurements on a two-axis tracker with a standard deviation of ±0.25% under clear-sky conditions. As the study progresses under a variety of field conditions and locations, the robustness of these results will be tested.
