I-V Curve Tracer

I-V Curve Measurement - The I-V curve measurement provides Isc, Voc, Imp, Vmp, Pmax, Fill Factor, and Performance Factor— the ratio of measured to expected maximum power. The measurement is typically performed at a combiner box, using the fuses to select the string under test.

I-V Curve Accuracy and Detail - The design of the PVA is optimized to accurately measure both standard and high efficiency modules, and the number of I-V curve points can be set to 500 for demanding applications.

High Throughput in Hot Conditions - All I-V curve tracers absorb energy with each measurement. The PVA’s high thermal capacity allows it to commission 1 MW in less than 2 hours without overheating, even in environments exceeding 43 C ambient.

Time-Saving User Interface - With a tablet PC (user provided) as your user interface you can perform more tests per hour and display the data in multiple easy to read formats. Save your measurements by simply touching the array tree. The PC interface also allows future addition of data analysis tools for the O&M application.

Data Analysis and Reporting - The I-V Data Analysis Tool, provided with the PVA, automates the process of preparing detailed, professional reports of your measurement results. The tool generates a table of the key performance parameter values for each string, group I-V graphs for each combiner box, and histograms showing how the data for each parameter is distributed.

SolSensor Wireless PV Reference Sensor

SolSensor provides irradiance, temperature, and module tilt data to the PV model. The model uses this information to predict the I-V curve shape at operating conditions, and to translate the measured curve to STC. SolSensor clamps to the module frame, automatically orienting the irradiance sensor in the plane of the array.

Irradiance Accuracy - The spectral response of SolSensor’s silicon photodiode sensor is corrected for the PV technology under test. Special factors are provided for multi- and mono-crystalline cells as well as 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 of these features, SolSensor makes accurate irradiance measurements over a broad range of technologies, sky conditions, and sun angles, allowing use of the equipment earlier and later in the day.

Temperature Accuracy - SolSensor provides two external thermocouple inputs for measuring module backside or ambient temperatures. Cell temperature can also be calculated directly from the measured I-V curve using methods described in IEC 60904-5. The PVA’s SmartTemp feature blends these two methods for best advantage. Temperature is calculated from the measured I-V curve at high irradiance, taken from the thermocouple at low irradiance, and derived from a blend of the two at intermediate irradiance values.

Wireless Range - SolSensor’s range to your PC is 100m, allowing you to test more of your array with each redeployment of the sensors. When the distance from your PC to SolSensor increases beyond the direct wireless range, the PVA’s mesh-type wireless network transparently switches to use the curve tracer as a high power relay station.
