ANTARIS SOLAR modules pass the salt spray corrosion test

The ANTARIS SOLAR AS M monocrystalline modules have proven their ability to withstand extremely salty outdoor conditions in a salt spray test performed by Photovoltaik-Institut (PI) in Berlin.
The test confirmed that ANTARIS SOLAR modules are particularly well-suited for installations in coastal regions with a high degree of salinity in the air and heavy rainfall.
Photovoltaic systems are always at risk of corrosion that could lead to decreased performance. However this risk is considerably higher in coastal areas, which are typically subject to greater than average rainfall and levels of salinity.
That is why ANTARIS SOLAR commissioned the Berlin-based Photovoltaik-Institut (PI) to put the ANTARIS SOLAR AS M series monocrystalline modules through their paces in a salt spray corrosion test according to DIN EN 60068-2-52.
The test took seven days to complete. During that time, the modules were sprayed four times with salt spray, for two hours at a time, with a salt concentration of 5.0 g/l. The modules were then stored in a damp chamber with a relative humidity of 93 percent and a temperature of 40 degrees Celsius. Finally the modules were subject to a three day drying process in a room heated to 23 degrees Celsius. This DIN test simulates, under laboratory conditions, several years of operation on a conventional roof-mounted installation.
After the entire test cycle had been completed, the ANTARIS SOLAR modules were checked for material damage and their performance capacity was tested. This inspection revealed no damage to the module structure, or any adverse impact on the performance of the modules. The ANTARIS SOLAR AS M modules in question showed no signs of external damage and their yield capacity was unaffected, even after intensive exposure to salt water and humidity.
“In order to guarantee the long service life of our modules, even in the most varied and potentially challenging conditions, we regularly subject them to tests that simulate extreme environmental factors,” says Dr. Michael Göde, Managing Director of ANTARIS SOLAR. “Recently, we successfully tested the resistance of our modules to ammonia. And now that they’ve also passed the salt spray corrosion test, we can confidently recommend our solar modules for use in particularly salty conditions, such as coastal regions.”
