Measure your solar PV system performance:-
The PVA-1500 is a cutting-edge IV Curve Analyzer tracer kit designed to measure with fluke solar tester system performance. With this high-precision testing equipment, you can reliably assess the health and performance of solar modules and arrays, making informed decisions to enhance their output and longevity. The PVA-1500 kit offers an array of advanced features, including high throughput I-V curve tracing, providing quick and detailed performance data. Its intuitive user interface enables easy navigation and real-time analysis, allowing for immediate identification of potential issues. By pinpointing problems early, you can maximize your solar energy production and minimize downtime.
Comprehensive measurements and efficient analysis:-
For commissioning, operations, maintenance, and troubleshooting of PV arrays, I-V curve testing is the most complete solar module performance measurement. Quick analysis of curve datasets aids in detecting outliers, and the stored Data Functions as a baseline for future performance inquiries.
Accurate I-V curve tracing:-
The PVA measures the I-V (current versus voltage) curve of a PV string or module using a capacitive load. The measurement is typically performed at the string level by connecting directly to the string or at a combiner box using the fuses to select the string under test. The number of I-V curve points can be selected at 100 or 500. Additionally, the PVA generates the P-V (power versus voltage) curve, Isc, Voc, Imp, Vmp, Pmax, fill factor, and performance factor (the ratio of measured to expected maximum power).
Time-saving interface:-
With a tablet or laptop (Windows only) as the user interface, perform more tests per hour and display the data in multiple, easy-to-read formats. Save your measurements by touching your customized array tree at the branch you are measuring. The software automatically calculates the expected I-V curve and displays the performance factor.
Advanced High-Efficiency PV Testing Capabilities:-
Accurate measurement of high-efficiency modules up to 30A: Highly efficient modules (>19% module efficiency) possess high capacitance, posing a challenge for some I-V curve tracers that may not be able to measure them. The PVA-1500HE2 is uniquely designed to measure all string types, even those with high-efficiency modules, up to 30A. Rapid performance in high-temperature environments: The PVA-1500HE2 operates with a swift sweep-to-sweep delay of 9 seconds (at Voc < 1350V). This results in the ability to measure 3.5 MW within an hour, even in high-temperature settings where standard curve tracers often fail due to overheating.
SolSensor™ Wireless PV Reference Sensor:-
The SolSensor™ provides irradiance, module temperature, and array tilt data to the PV model. The model uses this information to predict the I-V curve shape at these operating conditions and to translate the measured curve to standard test conditions. The SolSensor™ clamps to the module frame, automatically orienting the irradiance sensor to the plane-of-array.
The spectral response of the silicon photodiode sensor in the SolSensor™ is corrected for the PV technology under test. Special factors are provided for multi- and mono-crystalline cells as well as cadmium telluride (CdTe) and other thin-film technologies. The sensor is temperature-compensated and the angular response of each unit is calibrated for rotation and elevation. As a result, the SolSensor™ is accurate over a broad range of technologies, sky conditions, and sun angles, allowing I-V curve measurements earlier and later in the day.
The SolSensor™ provides two external thermocouple inputs for measuring module backside temperatures. Effective cell temperature can also be calculated directly from the measured I-V curve per IEC 60904-5. The PVA’s SmartTemp™ feature, optionally, blends these two methods for best accuracy.
The PVA and SolSensor™ communicate wirelessly with your PC via WiFi with a line-of-sight wireless range of 100m. That means no wires underfoot, quick setup, the ability to move around while troubleshooting strings, and flexibility to measure multiple combiner boxes with a single SolSensor™ setup.
Turn PVA data into key insights, visualizations, and customizable reports:-
Capture data in the field with the PVA Application and validate the results with the Data Analysis Tool (DAT), a Microsoft Excel™-based solution streamlining the analysis of PVA I-V curve data. It presents analysis results in multiple formats. It compiles key PV parameters in a string table, flags non-conforming strings, and delivers a statistical overview of the entire array.
Additionally, it visually combines string I-V curves at the combiner box level, offering a clear depiction of consistency and identifying atypical strings. The tool also generates histograms for PV parameters across the string population, and this data can be added to a customizable report exported as a PDF. The Data Analysis Tool [DAT] can be downloaded for free use with any PVA. Supported languages: English, French, Spanish, German, Italian, Traditional Chinese, Simplified Chinese, and Brazilian Portuguese.
