AC-modules are relatively large PV modules (approx. 100-200W) with anintegrated inverter, mostly attached to the back of the PV-module. The AC-module can directly be connected to the grid. The flexibility and the modularity of the AC-modules make this technology a very promising one. One of the question marks of this AC-modules technology, however, is the reliability and lifetime. The reliability tests that are performed at ECN consist of an accelerated lifetime test (high temperature test) and a temperature cycling test. Test results of the high temperature test will be presented. In order to determine realistic temperature distributions 12 AC-modules will be monitored while mounted outdoors on a tilted roof. 4 figs., 4 refs.
