Maximise solar energy and minimise solar panel downtime with the Fluke Solmetric PVA-1500 Series PV Analyser & I-V Curve Tracer. This high-precision instrument empowers engineers to assess the health and performance of solar modules and farms, enabling them to make informed decisions that enhance the output and longevity of PV arrays. Advanced features such as a high throughput I-V curve tracing (up to 1500V and 30A); a SolSensor™ PV Reference Sensor; and compatibility with Fluke’s PVA Application and Data Analysis Tool, combined with the Solmetric PVA-1500’s wireless connectivity and intuitive user interface facilitate detailed, efficient, real-time testing. As a result, engineers can pinpoint and address potential problems at an earlier stage, thereby reducing both downtime and repair costs while maximising solar energy productivity. Moreover, data may be stored to serve as a baseline for future performance inquiries. Consequently, the Fluke PVA-1500 is suitable for commissioning, operations maintenance, and auditing, as well as troubleshooting applications.
Using a capacitive load, the PVA-1500 measures the I-V (current vs voltage) curve of PV strings or modules. Engineers can set the number of I-V points at 100 or 500. Further to this, the Fluke PVA-1500 can generate the P-V (power vs voltage) curve, as well as determine Isc, Voc, Imp, Vmp, Pmax, fill factor, and performance factor (the ratio of measured to expected maximum power).
The SolSensor™ clamps onto the frame of the solar panel frame and automatically orientates the irradiance sensor to the plane-of-the-array. It provides the PVA-1500 Analyser with irradiance, solar module temperature, and array tilt data which the analyser uses to predict the I-V curve shape under real-world conditions and subsequently converts this to standard test conditions.
To ensure the SolSensor™ remains accurate when measuring an array of solar technologies under various sky conditions and sun angles, its silicon photodiode sensor includes:
As a result, I-V curve measurements may be taken earlier and later in the day. Effective cell temperature can be calculated from the measured I-V curve per IEC 60904-5. Alternatively, the SolSensor™ includes two thermocouple inputs for measuring module backside temperatures. To ensure the best accuracy, the PVA-1500 offers a SmartTemp™ feature which blends both of these methods.
The Fluke PVA-1500 Analyser and SolSensor™ communicate wirelessly with the engineer’s Windows laptop or tablet. Both offer a line-of-sight wireless range of 100m. This delivers maximum flexibility and efficiency as engineers can move around sites freely without cumbersome wires and enables multiple combiner boxes to be measured with a single SolSensor™ setup.
Furthermore, as the engineer’s laptop or tablet serves as the user interface, performing tests and viewing data in multiple formats becomes quick and easy.
Fluke’s PVA Application enables data capture in the field while the Microsoft Excel-based Data Analysis Tool facilitates streamlined analysis of I-V curve data. The Data Analysis Tool is available in multiple languages and can be downloaded for free. It offers the following capabilities:
There are two versions of the Fluke PVA-1500 available: the standard PVA-1500T2 and the high-efficiency PVA-1500HE2. The Fluke PVA-1500HE2 High-efficiency PV Analyser & I-V Curve Tracer differs in that it can measure all string types, including high-efficiency models up to 30A. Furthermore, the PVA-1500HE2 operates with a sweep-to-sweep delay of 9 seconds which means it can measure 3.5MW within an hour even under high temperatures.
Fluke’s high-efficiency PVA-1500HE2 PV Analyser & I-V Curve Tracer is available independently or as part of four kits. Please see the table below for details.
