7 Storage, Production and Package
7.1 Storage
The rank of moisture proof of the module is level 3. There is an obvious sign on the table of the
internal and the external packaging.
In the vacuum sealed bag, the module can be stored for 12 months when the temperature is below
40°C and the humidity is below 90% under good air circulation.
Humidity level is described detail as follows:
