PVA-1000S PV Analyzer Kit

I-V Curves and PV Performance Verification

For 1500V curve tracing see the PVA-1500.

For each string, the PV Analyzer measures the I-V (current vs. voltage) and P-V (power vs. voltage) curves with a single button click. The measured results are compared to the expected performance, taking into account the irradiance and module cell temperature at the time of the I-V measurement. The I-V Unit communicates wirelessly to your Windows tablet or laptop (not included), enhancing safety and allowing freedom of movement during testing. Automated data analysis and reporting save you time.

The PV Analyzer is designed to work as hard as you do. High measurement throughput means it can measure 1 MW in less than 2 hours--even in hot environments where other curve tracers shut down. The rugged enclosure is moisture and dust resistant. The incident angle corrected SolSensor is able to make accurate irradiance readings in lower light conditions extending your working window.

I-V curve testing is the preferred method for commissioning, O&M, and troubleshooting of PV arrays because it provides the most complete performance measurement possible. Populations of curves can be analyzed quickly for outliers and data can be archived as a baseline for future reference if performance questions arise.

Measure strings up to 30 Amps. The high current rating can be useful for measuring multiple strings in parallel, for example when harnessing before the combiner box is employed. Please note, however, the maximum current for strings of high efficiency modules with ≥ 19% efficiency is 10 Amps. For more information on high efficiency modules, see the Solmetric app note I-V Curve Tracing of High Efficiency PV Modules.

Purchasing Terms:

Shipping: For new products, shipping costs are not included in the published prices, but are quoted separately.

Returns: Orders may be returned within 30 days of purchase with a 10% restocking fee. Returns are not accepted for orders more than 30 days old.

Computer Requirements

The PV Analyzer requires a Windows laptop or tablet that is not included with a PVA purchase. Minimum requirements and recommendations are given below.

• OS: Windows 7, 8, and 10
• Processor speed: 2 GHz or more
• RAM: 2 GB or more
• Hard drive: 100 MB free space or more
• Screen resolution: at least 1024 x 600
• Bright outdoor readable display
• USB port
• An extended life battery, swappable battery, or external backup battery is convenient for full days of testing (a 4MW system can take 8 hours to measure every string.
• For extreme, hot, or dusty environments we strongly recommend the Panasonic Toughbook or similar.
