California based technology provider, Solmetric, has released a new version of its PV Analyzer.
The new wireless I-V curve tracer has the ability of measuring I-V curves for strings of up to 30 Amps and 1,000 Volts.
"We are happy to announce our newest 30 Amp I-V Curve Tracer," said Keith Rose, Solmetric vice-president. "It was developed to address the growing trend in large scale PV systems that use harnessed strings."
Large EPCs and project developers are continually focused on installation efficiency and cost reductions. For the past few years we have seen a trend in larger scale systems towards using 1,000-Volt strings, allowing for significant savings in wiring and cabling costs.
A newer trend called harnessing strings, where two strings are joined together before reaching the combiner box, seems to be gaining momentum. However, testing these strings to identify underperforming modules has been proven to be difficult and time consuming for operation and maintenance providers.
"The PVA product family was developed to provide a wireless solution with a focus on speed and accuracy in for in-the-field testing and troubleshooting," added Rose.
Solmetric's 30 Amp PV Analyzer follows the success of the previous version of the product. Customer features include: a database of more than 12,000 modules, its newest software version 3.4 and use of the Solmetric SolSensor wireless PV reference sensor with a wireless range of up to 100m.
Solmetric's proprietary software includes Angle of Incidence correction (AOI) factors boosting the accuracy of irradiance measurements taken in the field as well as their SmartTemp calculation, blending module back side temperature with effective cell temperature for the best cell temperature measurements.
Solmetric will present its new 30A Wireless I-V Curve Tracer at Intersolar from June 4-6 in Munich at trade show booth 554 in hall A1.
