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.

本数据集系《在水平单轴跟踪器后侧测量的空间辐照度图及其使用开源工具进行验证》一文中所用原始数据。该文发表于第47届IEEE光伏专家会议（PVSC）。通过开源工具对阵列后平面（POA）辐照度测量的扩展测量不确定度进行了估算，其值约为±9.3%。导致不确定度的三个主要因素为现场观测到的光谱失配、实验室校准（光源辐照度）以及角响应。对这些数据未进行任何校正。边缘模块位于跟踪器南侧边缘北约0.5米处，内部模块位于跟踪器南侧边缘北约21.5米处。第10号电池单元距离扭矩管最近，第1号电池单元距离扭矩管最远（参见文献中的图2和图3）。电池单元尺寸为125x125毫米，相邻电池单元间间隔约为2毫米。电池单元大致与跟踪器扭矩管处于同一平面内。
