Peak Power Measuring Device and Curve Tracer for Photovoltaic Modules
The devices of type PVPM enable the measurement
of the I-V-curve of photovoltaic modules as well as of
strings or arrays. By a newly developed procedure the
device can measure and calculate the peak power Ppk,
the Rs and Rp directly at the installation site of the PV
system. Calculation results and the diagram can be
displayed on the internal LCD-display.
The peak power is the power of a module under
Standard Test Conditions (STC) [1]. So far the very
complex measurement of the peak power was
possible only in particularly suited laboratories. By a
patented procedure [2], which was developed by
Professor Wagner at the University of Applied
Sciences Dortmund, the measurement with the
PVPM can easily be performed.
So the quality control of a PV system can be executed
fast and economically. This simple and meaningful
check in practice serves the certainty of the customer
and also that of the installer.
The Device
The PVPM is a mobile measuring device with
integrated battery supply and charge controller in a
durable metal housing. The
device has its own industrial
miniature PC and a highcontrast LCD display and
thus its function is
independent of other
The Measurement
The PVPM automatically measures the I-Vcharacteristic of the generator at a capacitive load.
From the measured data it calculates the effective solar
cell characteristic, Ppk and Rs. [2], [3]. The I-Vcharacteristic can be shown directly on the LCD
display. After the measurement the data are stored
automatically in a non-volatile storage and so are
available also later (in the office) [4]. The device
internally stores the data of several thousand
measurements.
