module testing

Acciona Energia’s 380 MW Aldoga solar farm, under-construction in Queensland, has engaged Spanish-headquartered Enertis Applus to initiate quality programs.

A white paper published earlier in December by PV Evolution Labs investigates the formation of performance damaging cracks in PV cells, based on mechanical stress testing of more than 40 commercially available PV modules. While the lab warns that susceptibility to cracking will change according to the specific bill of materials making up each module, certain technologies are shown to perform better than others.

German standards body TÜV Rheinland is introducing a new testing and certification program for pv modules. The program incorporates component specific tests and ongoing, random testing of running production lines. Hanwha Q Cells assisted in the development of the program, and this week announced it is the first manufacturer to receive the new Quality Control PV Certification.

Scientists led by the U.S. National Renewable Energy Laboratory (NREL) have developed a new stress testing protocol for PV modules, one designed to simultaneously expose modules to multiple stresses, as they likely would be in the field. Putting modules through this test, the researchers have already been able to reveal new information regarding backsheet degradation, and they promise new insights into other degradation mechanisms both known and unknown as well.

Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC standards and seek to guide manufacturers and investors on the best choice of materials – encapsulants in particular – when it comes to long term PID resistance.

The PV solutions division of DuPont Electronics and Imaging has revealed plans to work with the Fraunhofer ISE on optimizing testing protocols for crystalline silicon solar modules.
