Rooftop Module Test Station

photovoltaic Rooftop Module Test Station

A rooftop test station is installed on top of Building 226 on the NIST campus.  This station currently monitors modules from the same batches as those installed at each campus array in the same orientation as they are installed at the arrays.  Current-voltage (I-V) curves are measured at 1-minute intervals for each module, and the backside panel temperatures and the plane-of-array irradiance are measured at 1-second intervals. obtained for each module along with backside panel temperatures and the irradiance in the plane of each module at 5 minute intervals.
