Raw data used in "A Spatial Irradiance Map Measured on the Rear Side of a Utility-Scale Horizontal Single Axis Tracker with Validation using Open Source Tools"

This is the raw data used in the publication "A Spatial Irradiance Map Measured on the Rear Side of a Utility-Scale Horizontal Single Axis Tracker with Validation using Open Source Tools" presented at the 47th IEEE Photovoltaic Specialists Conference (PVSC). The expanded measurement uncertainty of the rear plane of array (POA) irradiance measurements was estimated at ±9.3%. The three principal components driving the uncertainty are the spectral mismatch observed in the field, the lab calibration (light source irradiance), and the angular response. No corrections are applied to these data.Edge modules are about 0.5 m north of the tracker's south edge. Inner modules are about 21.5 m north of the tracker's south edge. Cell Number 10 is the closest to the torque tube, Cell Number 1 is the farthest away from the torque tube (see Fig. 2 and Fig. 3 from publication). Cells are 125x125mm with ~2mm spacing between each cell. Cells are approximately in plane with the tracker torque tube.
