CNPV Passes 2PFG and IEC 61701 for Ammonia and Salt Mist Corrosion Resistance

[23. 9. 2011]

LUXEMBOURG and DONGYING, China, Sept. 22, 2011 /PRNewswire-Asia/ -- CNPV Solar Power SA, a public limited liability company organized under the laws of the Grand Duchy of Luxembourg and a leading integrated manufacturer of solar photovoltaic products, announced today that it has passed external, independent testing and certification for Ammonia and Salt Mist Corrosion Resistance.

With the continuous expansion and the technological advancement of photovoltaics worldwide, special issues take on additional importance for manufacturers as well as for buyers and investors. This includes extreme exposure to salty air, as well as exposure to ammonia. Longevity of installation is being investigated in greater depth, with references to historical data, accelerated aging and developing industry standards to establish viable, credible criteria for evaluation.

The IEC ammonia standard is currently at draft stage, and considers existing standards for electrical systems, coating corrosion protection and sulphur dioxide contamination of metal surfaces (ISO 12944, ISO 3231, ISO 6988 and DIN 50018 in particular). The current approved test is named 2PFG. The test subjects the modules to extreme concentrations of ammonia and observes any degradation present. It also checks the modules against power loss, and retention of insulation properties. CNPV passed these tests with flying colours when evaluated by TUV Rheinland.
