Solmetric Releases PV Analyzer


Solmetric Corp. has introduced the PV Analyzer (PVA), an electrical test product for verifying and troubleshooting photovoltaic array performance.

For each string, the analyzer measures current and power as a function of voltage. Measured results of the I-V and P-V characteristics are compared to the performance predicted by advanced built-in models. When predicted results match modeled results, system performance is verified.

Any differences can offer insights into potential performance issues such as excess series resistance, failing cells or module mismatch, the company says. The PVA solution is suitable for system verification during installation and for troubleshooting performance problems.

The Solmetric PVA compares measured and modeled array performance. Several models are available, including the advanced model from Sandia National Laboratories. To specify the system configuration, the user chooses the module and inverter type, the number of modules, and the array orientation. Strings up to 600 V and 20 A can be measured and compared to the model.

Currently the PV Analyzer is available for sale in North America, and international versions are planned for release later this year.
