UV chamber for preconditioning test

In PV modules a lot of different components are exposed to the sunlight. The IEC 61215 therefore defines a UV preconditioning test (MQT 10) to test if these components can withstand the UV radiation of the sun.

In our test chamber the UV radiation is up to 5 times the sun intensity to accelerate the test as it is requested in the UV preconditioning test.

During the test the module temperature is kept constant at 60°C in a special temperature chamber. We deliver our UV preconditioning chamber turnkey including the data acquisition unit, radiation and temperature sensors.

For waste heat disposal, the chamber is equipped with a water/air heat exchanger that can be connected to a cold water grid. This minimizes the heat load in the room were the chamber is installed.
