PVA Data Analysis Tool

The Data Analysis Tool (DAT) is an Microsoft Excel™ based tool that automates the analysis of large blocks of PV Analyzer I-V curve measurement data. Results of the analysis are displayed in many different formats. A string table lists the key PV parameters for each string, flags any strings that do not conform to your test limits, and provides a statistical summary of all strings in the array. String I-V curves are combined on common charts at the combiner box level, graphically showing the consistency of the results and identifying any non-typical strings. The tool also provides histograms for each of the PV parameters for the entire string population of the array. The tables and data can be added to a customizable report that can be exported as a PDF.

The Data Analysis Tool (DAT) can be downloaded for free use with any PV Analyzer. Click the link to the left to download.
