Why TO use amorphous silicon thin film → The world's lightest technology

 easy to integrate  easy to carry and to ship  easy to carry and to ship  unbreakable  don’t need special reinforcement

→ The more efficient in the light

 module power provided best performance with low light  long term efficiency in one day  long term efficiency in one day  10%-20% more energy per installed Wp due to superior low-light performance.  Amorphous silicon has a superior irradiance coefficient. 5 coefficient.  Better performance at non- ideal angles of incidence and in low and diffuse light.  Reference : Ruther, 2003.

Why TO use amorphous silicon thin film Don’t SPEAK about Wpeak any more but About Performance ratio

 Reduction of the STC standard size : the performance ratio (PR[%]) is the annual system efficiency divided by the nominal module efficiency at STC.  PR=Yf/Yr= nav/nSTC  ILAND-XUNLIGHT modules are in the TOP 6

Summary When using amorphous silicon modules (a-si)? FOR non optimal orientations; FOR Flat roof or façade; FOR Flat roof or façade; When the roof structure does not support heavy loads.

HOW MANY MODULES A-SI COULD YOU INSTALL ON A FLAT ROOF?  YOU CAN INSTALL MORE A-SI POWER ON A FLAT ROOF THAN C-SI, BECAUSE C-SI HAVE TO BE INSTALLED ON STRUCTURES THAT CAUSE SHADOWS BETWEEN EACH OTEHR.  IN THE CASE OF EQUAL POWER INSTALLED, A-SI PRODUCES MORE ENERGY  IN THE CASE OF EQUAL POWER INSTALLED, A-SI PRODUCES MORE ENERGY IN A DAY THAN C-SI (SEE EXAMPLES ABOVE). SO THERE IS NO LOSS OF PERFORMANCE TO INSTALL AMORPHOUS SILICOM TECHNOLOGY!

How much does cost an a-si facility? How much does cost an a-si facility? The price is calculated in Euro/Wp;

p

The Wp price for an asian c-si module unit is cheaper than an a-Si module unit; But The installed price of an A-Si facility can be cheaper than a C-Si. Because with a-si we don’t need bearing structure, ventilation system,

• etc. the A-si is just welded on it’s substrate;

An a-Si facility is less expensive than a c-Si facility and with a betterpower performance (see details below).
