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.

New in version 4.5:

• Fixes some graphical issues

New in version 4.4:

• Runs faster
• Data from multiple PVA projects can be merged into a single analysis file and report
• Populations of I-V curves can be normalized in order to highlight differences in curves without the variations from irradiance or temperature
• I-V curves can be translated to STC, average, or other conditions
• You can now assign a custom project title
• Array tree locations for strings are more concise
• I-V plot legends can be turned on/off
• 4th order MPP fit can be turned on/off
• Degradation in performance factor can be modeled based on annual degradation
