6 FAQs about [Photovoltaic inverter aging test equipment]

Are there opportunities for accelerated aging testing in photovoltaics?

Discussions with industry and observations by U.S. Department of Energy (DOE) and National Laboratory staff identified a growing interest in the problems and opportunities associated with accelerated aging tests in photovoltaics.

Are accelerated aging tests based on IEC 61730 & 61215?

Practically every new technology on cell and on module level is being tested by accelerated aging tests according to or at least based on IEC 61730 and IEC 61215. This underlines the importance to understand these tests and the obtained results in order to correctly evaluate the reliability of new technologies.

What causes a positive power deviation after the aging test?

The absence in elevated temperatures of the ML test coincides with a strongly reduced fraction of modules with a positive power deviation after the aging test, further supporting the assumption that the positive power deviation is partly caused by elevated temperature.

Which aging tests are performed on two modules of the same type?

The aging tests DH1000, TC200, and Sequence C are each carried out on two modules of the same type, respectively. Other tests e.g. hot-spot, ML, as well as Sequence B and B1 are typically performed only on one sample.

How many modules failed the aging test?

TABLE 3. Mean deviation and 95th percentile of the relative power degradation of two modules of the same type after aging tests For Sequence C, in 17.4% out of 218 module pairs, at least one module failed the criteria. In 57.9% of these, only one module failed.

Is the solar photovoltaic industry expanding?

The solar photovoltaic industry is expanding at rates that were only dreams a few years ago. Multiple new manufacturers (some with new PV technologies) are seeking to gain entry into the marketplace and existing manufacturers are aggressively expanding their manufacturing lines.
