What is a TestLab PV module?

At the accredited TestLab PV Modules, founded in 2006, Fraunhofer ISE tests PV modules according to IEC and European standards for design qualification and type approval. In Raman spectroscopy, critical points of the module are irradiated with a laser.

How many pages is a photovoltaic module report?

This report consists of 12 pages, including annexes, and cannot be reproduced in part without a written permission. IEC 61215-1-1:2016 / EN 61215-1-1:2016 Terrestrial photovoltaic (PV) modules – Design qualification and type approval – Special requirements for testing of crystalline silicon photovoltaic (PV) modules. Low solid. No clean flux

How do you determine the robustness of a PV module?

With a special compressed air gun, developed by Fraunhofer ISE, the robustness of the module is determined by firing hail stones at defined, standardized target points (such as the conductor connection points). Our services include all measurements and tests for the design qualification and type approval of PV modules.

How does a hot-spot test affect a photovoltaic module?

The hot-spot test motivated manufacturers to use bypass diodes, which protect the modules when the photocurrent generated by each cell shows variations because of partial shading or cell damage. These three changes helped to avoid important design flaws, thus dramatically decreasing failure rates.

How to detect defects in infrared images of PV modules?

Image processing scheme comprising filtering, color quantization, and canny edge detection can be used for detection of defects with differing severity in infrared images of PV modules . This scheme can locate normal operating, mild defective and severe defective regions in infrared images of PV modules.

Why do PV modules have defects?

The defects generated during manufacturing phase grow with the passage of time as the PV module is subjected to various kinds of thermo-mechanical loads during subsequent stages of life . The transportation of modules, handling, and installation might become a source of mechanical loads and produce some defects .
