Eurotest also offers accredited external electroluminescence tests.

Electroluminescence is the only type of test that can identify and analyse defects on photovoltaic panels that are not visible to the naked eye (breakages, cracks, microscopic fractures on cells and PID).

This test method, accredited by Eurotest, allows us to offer a vital service in all cases where it is essential to understand the reasons for a decline in performance. The possibility to carry out tests directly on site means that disputes relating to disconnection from the string, transport and handling of the panels can be avoided; moreover, related costs are much lower (transport and lack of power generation), guaranteeing an extremely reliable result.

Eurotest has made this additional commitment in order to support its partners, especially as regards consulting and tests in the field, needs that are becoming more pressing as the number of photovoltaic installations increases.
