I-V Curves and PV Performance Verification

The PVA-1500T PV Analyzer Kit is a 1500 volt I-V curve tracer with built-in PV performance modeling and advanced wireless irradiance, temperature and tilt sensing. It provides unprecedented measurement throughput and accuracy and delivers deep insight into the performance of your arrays.

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 user interface is via your Windows tablet or laptop (not included), which connects via WiFi to the PVA, and presents a large clear display of your results in the field.

Irradiance, module temperature, and tilt are measured with the SolSensor. The I-V Unit communicates wirelessly to the Solsensor, enhancing safety and allowing freedom of movement during testing. Automated data analysis and reporting save you time.

Measure strings up to 30 Amps. This 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.

Unprecedented Measurement Throughput

The PV Analyzer is designed to work as hard as you do. The PVA-1500V4 (and older S, V2, and V3 models) had the best measurement throughput of any 1500V curve tracers in the industry--until now. The 'T' in the PVA-1500T stands for 'Throughput' and means 2x higher I-V measurement throughput and 2x longer run-time before cool down when compared to the PVA-1500V4 (and S, V2, and V3). Sweep-to-sweep delays are now 9 seconds in the 'T' versus 18 seconds in the older models (at Voc<1350V). The PVA-1500T can measure 3.5 MW in less than an hour--even in hot environments where other curve tracers over-heat and shut down.

In an example PV system with Voc=1300V, 16 strings per combiner box, 9 seconds between each of the I-V sweeps followed by 5 minutes to move to the next combiner (during which there are no measurements), the PVA-1500T can run all day long at 75°F (25°C) ambient temperatures and can make 330 measurements at 113°F (45°C) ambient before a longer cool-off period is required (assuming no direct sunlight on the PVA I-V Unit).

Furthermore, the incident-angle-corrected SolSensor is able to make accurate irradiance readings in lower light conditions extending your working window.

Save Time, Reduce Risk, Maximize ROI

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. Maximize your ROI--Return On Irradiance!
