THE TESTING

CAPACITIES

ENVIRONMENTAL CHAMBERS

Environmental chambers are the heart of any PV test laboratory. It is essential to be able to simulate environmental conditions in an accelerated manner to assess product quality and reliability. Twenty-five plus (25+) years of product lifetime must be simulated with confidence within a reasonable time period. The IEC developed test procedures intended to simulate such product lifetime under average global environmental conditions. Desert climate in the Middle East requires more stringent test procedures requiring equipment with extended capability.

The TC chambers are very flexible, able to perform various IEC test procedures with the same chamber.

Salt Mist and Corrosion Chamber

Corrosion testing on PV modules is essential, especially when products are installed close to the sea or other areas where corrosive gases or materials such as salt are present. IEC issued the first specifications in the early 90’s. IEC60068, the revised test procedure for salt spray and corrosion test requirements for PV modules IEC61701-2 has been issued in 2014. This chamber is fully compliant with the new revised test requirement.

Sand Spray Chamber

Essential for the Middle East installations is to expose the products to “Sand Storm” conditions. This environmental factor can seriously harm products. Test procedures for PV modules simulating sand storms do not exist today. KACST is working with expert organizations to establish a test procedure simulating this factor. KACST will offer tests in this sand spray chamber as part of the Desert Protocol procedures.
