At Intersolar North America 2014, taking place July 8-10 in San Francisco, Solmetric, a software and tool developer for the solar installation industry, has a lot to offer, including a workshop and new product extension.
The Commissioning and Troubleshooting PV Arrays with I-V Curve Tracing workshop describes the use of I-V curve tracing instruments to commission, audit, and troubleshoot the performance of PV arrays. The training covers the entire spectrum of topics from how I-V curve tracing works to analyzing and reporting measurement results. I-V curve tracing is the most comprehensive performance measurement that can be performed on a PV array.
This training will explore the use of metrics like Performance Factor and Fill Factor, which curve tracing provides, to identify underperforming strings and modules. The six common deviations from expected I-V curve shape will be explained and examples of physical causes will be given. The company will also give examples of how the selective shading method can speed troubleshooting by identifying the problem module in a string without disconnecting the modules from one another.
Solmetric recently released a new version of their SunEye Extension Kit. The new design of this SunEye accessory was developed to give installers greater flexibility. The new Extension Kit Platform allows for customers to attached the SunEye to many different types of extension poles. This design includes a tightening mechanism that allows customers to choose their own telescoping poles.
