Frequently Asked Questions about the PV Analyzer
For PVA-1500S/V2/V3/V4/T/HE, PVA-1000S, PVA-600+
The Data Analysis Tool (DAT) is an Excel program that is recommended for validating results in the field, analyzing large PVA data sets, and for generating professional reports of your measurement results. For more info about the DAT go here.
Note: the DAT works best with MS Excel and Windows 10 or Windows 11 operating system fully updated. The source (“exported”) data also needs to be local on the PC. IF you get run-time errors, please update Windows, re-install MS Office, and install/repair vc/redist x64.exe (see link below). Contact Solmetric Support for assistance.
Note: The PV Analyzer application and the Data Analysis Tool work best with Microsoft Windows 10 or 11 with ALL recommended Updates installed, including the latest Visual C++Redistributable x86 and x64 updates from option for each. If they are missing, please install them via these links:
Office DB Engine (Install if missing in Apps, and/or PVA app crashes on module database or array tree edits):

Poor PV source performance hurts the bottom line. Fortunately, performance problems show up in the measured I-V curve. This article describes the six ways that measured I-V curves can deviate from normal curve shape and provides an Array Troubleshooting Flowchart to help you identify the most likely causes.
The PV Analyzer user saves the I-V curve measurement of a PV string by just touching the corresponding branch of a graphical ‘array tree.’ This Application Note describes use of the Array Navigator, including the Symmetrical Tree Builder, that lets you quickly customize your array tree and name the layers to exactly match the engineering drawings. This improves the reliability of the measurement process in the field and assures that the measurement results will be correctly labeled in your final report.
