PV Module Tester

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.

Features:

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.
