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 off the support → 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. coefficient.  Better performance at non- ideal angles of incidence and in low and diffuse light.  Reference : Ruther, 2003. 5

WHY TO USE AMORPHOUS SILICON THIN FILM → The more efficient in the heat Marathon des Sables 2014 %  the more efficient in south countries c-Si  the more resistant a-Si a-Si T  Reverse effect of the ratio efficiency/m2 on c-Si cells and other technologies. The initial yield of each cell based on STC calculation standards.  Reference : SUPSI, 2008.   Conclusions : to compare STC standard (Watt peak - Conclusions : to compare STC standard (Watt peak - Wp) of different technologies does not give proper information on the efficiency of a cell for a period of time and with temperature and light effects. 6

Why TO use amorphous silicon thin film Don’t SPEAK about W peak any more but About Performance ratio Xunlight Real World Perform ance Ratio 400  Reduction of the STC standard size : the performance ratio (PR[%]) is the annual system efficiency divided by the nominal module efficiency at STC. 300  PR=Y f /Y r = n av /n STC quency  ILAND-XUNLIGHT modules are in the TOP 6 of Freq Xunlight t 200 200 performance ratio (Tested by California Energy Commission). 100 Yf: production yield in [kWh/kWp] Yr: reference yield production: energy theoretically attainable by kWp measured in [kWh/kWp] at nominal STC conversion efficiency in module plane. nav= average system efficiency in module plane nSTC= module STC efficiency 0 0 78.0% 81.0% 84.0% 87.0% 90.0% 93.0% 96.0% 99.0% Performance Ratio (CEC PTC Rating/STC Rating) 7

WHY TO USE AMORPHOUS SILICON THIN FILM → Ecological products  the most ecological products on the market  100% recyclable  no risk of pollution  no risk of pollution  0.8 years payback time for a 25 years system lifetime.  Reference : Fthenakis, 2008  Reference : Fthenakis, 2008 8

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!
