IEC 61215

The IEC 61215, respectively EN 61215, comprises the examination of all parameters which are responsible for the ageing of PV modules and describes the various qualification tests on the basis of the artificial load of the materials. In particular one differs between the following load groups:

Sunlight incl. UV
Climate (changing of climates, coldness, warmth, humidity)
Mechanical load (hail, wind suction, wind pressure, snow)

The tests are judged to be passed, if after the qualification tests no major visual defects are detected and the output power has not or only slightly degraded from its initial value.

The qualification certificate corresponding to IEC 61215 has gained acceptance in the past few years as the quality symbol for crystalline PV modules. Nowadays such a certificate is required for most national and international funding programs.
