Kaneka decided to begin research into thin film silicon PV modules at an early stage. This has allowed the company to assume a leading position in theindustry over the past 20 years. Kaneka's accumulated expertise now makes it possible to offer next-generation energy all over the world through its advanced PV systems that empower individuals to take a proactive environmental role in their daily lives. Kaneka'samorphous silicon PV module (a-Si) has superior light absorption per nominal watt power. Compared with mono-crystalline silicon PV modules (c-Si) or poly-crystalline silicon PV modules (poly-Si), it generates considerably more power per nominal watt power. Kaneka modules come with a 5 year warranty on material defects and workmanship after shipment from Kaneka. The warranty period with respect to power output is 25-years after shipment from Kaneka at 80% of the specified minimum output of the module. |

Many Reasons To Reccommend Kaneka Thin-Film PV!
|
Superior Performance Under High-Temperature Conditions Crystalline-Si PV modules lose some power-generating capability with rises in temperatures. But Amorphous-Si PV modules generate higher power during summer time. Amorphous-Si PV modules can deliver maximum performance during summer when the electricity is needed most for air-conditioners in houses and offices.
*Kaneka Silicon PV's generated watt-power is approximately same as that of other crystalline silicon PVs during the winter months, but in summer the Kaneka Silicon PV generates significantly more power compared to other crystalline silicon PVs. *NEDO : New Energy and Industrial Technology Development Organization. |
Better Actual Watt-Power Generation Compared With Crystalline Silicon PV Modules Kaneka's amorphous silicon PV module (a-Si) has superior light absorption per nominal watt power. Compared with mono-crystalline silicon PV modules (c-Si) or poly-crystalline silicon PV modules (poly-Si), it generates considerably more power per nominal watt power.
Assuming that the total solar radiation per year (1.323kWh/m2) is 100%, Kaneka Silicon PV can produce 90.95% of actually generated watt-power, much higher than that of other crystalline silicon PVs (80 to 84%). |

Shorter Energy Pay-back Time (ept) EPT is the time a PV module to "pay back" the energy used in its manufacture by its own power generation. The EPT of amorphous-Si PV is 1.6 years, which is approximately 6 months shorter than that of crystalline silicon PV (2.2 years).EPT is one of the most important aspects when evaluating the ecological benefit of PV systems.  |
Enviomentally Friendly The single junction a-Si layer can be made extremely thin.The thickness of a-Si cell is 0.3 |
, which is 1/600 of that of crystalline silicon cell (approx. 200
