DESERT® & TROPIC® Technology: Humidity Resistance

Relative humidity in tropic regions

Even in desert regions the relative humidity can get very high in the morning hours, reaching values of up to 100% relative humidity in January. Relative humidity causes, due to delamination of backsheet and encapsulant, lesser adhesion of glass or junction box and can cause safety issues. Moreover, in standard encapsulants penetrating moisture can rinse certain additives, whereby degradation can be taken place. All these processes will be accelerated by high ambient temperatures.

The J.v.G. technology Diamond DESERT Foil, together with our DESERT Lamination Process, prevents moisture penetrating into the module. For this reason, the J.v.G. technology DESERT Modules are very suitable for locations with high humidity.
