Thin-film terrestrial photovoltaic (PV) modules - Design qualification and type approval

IEC 61646:2008 lays down requirements for the design qualification and type approval of terrestrial, thin-film photovoltaic modules suitable for long-term operation in general open-air climates as defined in IEC 60721-2-1. This standard applies to all terrestrial flat plate module materials not covered by IEC 61215. The significant technical change with respect to the previous edition concerns the pass/fail criteria.

Modules photovoltaïques (PV) en couches minces pour application terrestre - Qualification de la conception et homologation

La CEI 61646:2008 fournit les exigences sur la qualification de la conception et l'homologation des modules photovoltaïques en couches minces pour application terrestre et pour une utilisation de longue durée dans les climats généraux d'air libre, définis dans la CEI 60721-2-1. La présente norme s'applique à tous les équipements à module à plaque plane non couverts par la CEI 61215. Une modification technique significative par rapport à l'édition précédente concerne les critères d'acceptation/de refus.

Foreword
The text of document 82/512/FDIS, future edition 2 of IEC 61646, prepared by IEC TC 82, Solar
photovoltaic energy systems, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 61646 on 2008-06-01.
This European Standard supersedes EN 61646:1997.
EN 61646:2008 includes the following significant technical changes with respect to EN 61646:1997:
The major change is in the pass/fail criteria. It no longer relies on meeting a plus/minus criterion before
and after each test, but rather on meeting the rated power after all of the tests have been completed and
the modules have been light-soaked. This was done to eliminate the technology-specific preconditioning
necessary to accurately measure the changes caused by the test. (Some modules lose power in light
while others lose power during dark heat.) Since all modules must work after exposure to light, this
seemed like a good approach and will streamline the test procedure, hopefully reducing the testing cost.
– updated normative references;
– added a definition of “minimum value of maximum output power”;
– modified the wording in major visual defects to allow some bending and misalignment without failure;
– added requirements to the report from EN ISO/IEC 17025;
– removed the “Twist Test” as was done from EN 61215, since no one has ever failed this test;
– made the pass/fail criteria for insulation resistance and wet leakage current dependent on the module
area;
– added the temperature coefficient of power (δ) to the required measurements;
– modified temperature coefficient section to allow for measurements under natural sunlight or a solar
simulator;
– deleted reference plate method from NOCT;
– added apparatus sections to those test procedures that did not have apparatus sections in
EN 61646:1997;
– rewrote the hot-spot test;
– eliminated edge dip method from wet leakage current test;
– changed mechanical load test to 3 cycles to be consistent with other standa
