Product features

Tandem structure with an amorphous and a microcrystalline silicon layer offering a stabilised module efficiency of up to 9.5%.
Optimised for grid-connected roof mounting PV systems.
Use of white glass, encapsulation material, weather protection film and a newly designed silver anodised aluminium frame for long-term use. This guarantees simple and safe installation.
Module can be operated and installed by one person (1.42 m2, frame width 1 m, weight 18 kg).
Higher energy yields per watt at high temperatures.
Output: connection cable with waterproof plug connector.

Some reasons to install SHARP NAF128GK Thin Film better than Poly or Monocrystalline modules:

Good performance proven in warm & sunny regions of the world (see picture bellow). SHARP NAF128GK is better than Crystalline models, in Low Latitudes (High Temperature regions):

In that kind of Low Latitudes, where temperature is high, the production of Thin Film is better than regular crystalline models:

As the result of making an analisys with PVsyst software, is very interesting to see the advantages of install SHARP NAF128GK, instead of Crystalline modules.
