EETS range of PV module testers are designed to achieve a high accuracy measurement and archived record of output.
They may be constructed as module face down, face up or vertical, (types D,U,V)
The EETS PV module tester measures the current -voltage (I-V) characteristics of PV modules up to 2.0m x 1.5m. The steady-state light is adjusted to the required intensity and is measured by a calibrated reference cell located in the test plane.
A data acquisition system acquires the module performance data and controls the electronic load which varies the resistance across the module output terminals. The computer plots the I-V curve and displays a variety of module characteristics. Curves and data can be printed and archived.
Measures and displays the following module parameters:
- Complete I-V curve.
- Open-circuit voltage, Voc.
- Short-circuit current, Isc.
- Maximum power point, Pmp.
- Module efficiency.
- Fill factor.
- Module temperature, oC.
- Data and I-V curve corrected to standard conditions.
- Conforms to IEC 904-9 Class C or Class B.
- Optional alternate thin film reference cell.
