In March of 2011, Canadian solar panels passed the ammonia corrosion test that is recognized as a benchmark test for longevity of solar panels. This becomes significant where the solar modules are to be installed on buildings with heavy agricultural chemical production. The ammonia released into the atmosphere easily corrodes substandard panels leading to water seeping into the cells and thereby causing short circuits as well as irreparable damage.
The company voluntarily submitted their modules for the testing process certain that their stringent production procedures would come good. This development is decidedly an advantage that Canadian solar panels will have in seaside homes. It also greatly aids the company’s push to establish bigger footing in the Asian and Pacific regional markets like Japan, Indonesia and Thailand.
The modules were also subjected to IEC60068-2-52 Ed.2 (Severity 1, Environmental testing), standards of which were just adopted in 2011. The specification Severity 1 is used for equipment and products expressly manufactured for use in directly marine environments or at least exposed to a sea environment for most of their lifetime usage. Thus the tests are no less stringent than what such implements as ship radar and deck equipment would be subjected to in quality assurance.
For a piece of equipment to be considered as having passed Severity 1 tests, it must undergo 4 cycles of testing, lasting a total of 28 days. In each of the cycles, the modules are subjected to a continuous spray of 5% sodium chloride solution for up to two hours each time. The panels are then stored for a whole week at humidity conditions of 85% as well as temperatures of 35 degrees Celcius.
What is most notable about this laboratory Severity 1 procedure is that the procedure is repeated four times in each test cycle. The conditions are decidedly stringent to ensure that they replicate the sort of pressure the PV modules would be put to in the entirety of their lifetime. There is no better proof that Canadian Solar PV modules are crafted to withstand the severest environmental conditions without affecting their effectiveness.
The modern consumer is decidedly very different from the one of yesteryear. Increased market liberalization has brought about a level of product choices that were virtually impossible to imagine only a few years ago. It is with this in mind that the news of the latest certification awarded to Canadian Solar PV modules is such welcome news for the discerning consumer.
