FMT-500 – Light I-V Testing for Modules

Advanced analysis of solar modules including light I-V and Suns-Voc data. Capability to accurately measure high-efficiency modules.

Sinton Instruments’ FMT-500 measures any crystalline silicon module, including high-capacitance, high-effciency modules, using patented electronic load technology

Product Overview

The FMT instrument has been designed to have the highest possible accuracy for measuring high-efficiency silicon solar modules. This is accomplished using a patented multiflash technology.

The standard analysis includes the commonly reported parameters for module testers, but is supplemented with the Suns-Voc analysis that precisely indicates the source of power loss due to shunt and series resistance effects.

Over 7 GW of product has been tested to date using the FMT instrument. It is also ideal for R&D.

The FMT interface displays both I-V and Suns-Voc data. This permits direct comparisons of module data to cell data and quick identification of series resistance, shunting, and cell mismatch.

The FMT-500 illumination area uniformity is Class A (±2%) uniformity over a 1 x 1.5 m test area. The figure above shows data from a setup that achieved Class A (±2%) uniformity over 1.2 x 2.4 m.
