About FWAVE solar cells and their power generation characteristics

Because we, at OS CO., Ltd, emphasize the importance of our product quality, we use the made in Japan FWAVE amorphous silicon-based solar cells. These reliable glass free modules possess remarkable properties. We believe that they are the next generation solar cells.

Stable power generation
When crystalline solar panels loose a part of their efficiency at high temperatures, FWAVE solar cells maintain their power generation. Moreover, because the amorphous silicon-based solar sheet is able to generate power even in low sunlight exposure conditions (in the morning, in the evening, on cloudy days) it generates 10% more power per year than a crystalline silicon solar panel.

Superior durability
Highly resistant to high temperatures and humidity.
The module comprises a fluorine based protective layer and a polyethylene based sealant which enable maintaining its performance in extreme conditions. Under an evaluation environment where temperature is up to 85℃ (185°F) and under a relative humidity (RH) of 85%, the module maintains its performance for more than 10,000 hours.
Furthermore, glass free, it offers high resistance to impact, shock, twisting and bending. A stepping stone will not break it.
Flexible (supple, bendable)
Because the ultrathin solar sheet offers remarkable flexible and bendable properties, it can be rolled up to make storage and carrying easier. Its lightweight and slim design allows easy carrying anywhere, unlike crystalline solar cells that do not possess these characteristics.

In terms of temperatures
FWAVE solar cells , due to annealing effect on the module, enable high and constant power generation even in high temperature and high humidity conditions. 温度(気温)に関して
In terms of sunlight exposure
FWAVE solar cells can generate power even in low sunlight exposure conditions. In the morning or in the evening, or even on cloudy days, FWAVE solar cells are still more efficient than crystalline silicon solar cells.
Due to the internal resistance , the module offers a low efficiency loss even in low sunlight exposure conditions.照度(朝・夕・曇天)に関して
