6 FAQs about [Photovoltaic inverter automatic aging line]

Does aging affect the electrical performance of PV modules?

The aging impact on the electrical performance of the PV module connecting with the grid was tested by Azizi et al. . The results demonstrated the degradation of approx. 1%/year in the rate for PV module maximal power-point; in addition, module resistance evolution was estimated to be approx. 12.8% for 20 years.

Do accelerated ageing tests improve the quality of PV modules?

The Know-How on degradation effects and rates as well as on failure modes of PV modules in the field and related accelerated tests were improved. Accelerated ageing tests, with subsequent characterization, are in general used to ensure and measure the quality of PV components and are used for a long time .

Why is accelerated ageing and field performance of PV modules increasing?

The research activity on accelerated ageing and field performance of PV modules has significantly increased during the last decade. The increasing interest finds its causes in the growing market accompanied with the technological development and diversification, along with the rising importance of PV for the financial sector.

Do PV modules degrade over time?

PV module components degrade over time during operation, which leads to electrical performance loss [7 – 10]. The service life of a PV modules depends mainly on the BoM, PV technology and the climate which the PV module operates in, as these two factors highly influence the type and rate of degradation mechanisms.

Can accelerated testing predict service life of PV modules?

The final goal of accelerated testing is predicting the service life of PV modules under normal outdoor conditions. The chapter gives an overview on developments related to service life prediction (SLP) of PV modules using data of accelerated ageing tests and the correlation of these tests with outdoor operation and effects. 8.1.

What is relative humidity exposure in accelerated ageing tests on PV modules?

Relative humidity exposure in accelerated ageing tests on PV modules is facilitated in climatic cabinets, which are available in all sizes. Most make sure to fit at least 2 PV modules simultaneously. The commonly used test for humidity exposure is the so-called DH test at 85 °C and 85% r.h. for 1000 h, as defined in IEC 61215.
