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.
Unprecidented Measurement Throughput
The PV Analyzer is designed to work as hard as you do. The older PVA-1500S/V2/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-1500S/V2/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 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 measurmeents), 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!
Included with the PVA-1500T
SolSensor-300 Wireless PV Reference Sensor (included):
Irradiance, module temperature, and tilt readings are captured at the instant the I-V curve is measured. Improves effectiveness of expected performance models. The SolSensor has a range of more than 300 ft and includes a module rail clamp and precision mounting system for POA alignment.
PVA Test Leads (included):
1500V rated alligator-clips ("dolphin" clips) enable connecting directly to combiner box bus-bars. more...
I-V Data Analysis Tool (included):
Excel macro for analysis of populations of curves and data plus report generation. more...
30A Measurement Capability (included):
Measure up to 30A strings. This can be useful for measuring many strings in parallel, for example when harnessing before the combiner box is employed. Please note, however, that parallel strings of high efficiency modules can not be measured in parallel even if the total current is less than 30A.

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
