<p class=MsoNormal><font size=4 color=blue face=Arial><span style='font-size:
14.0pt;font-family:Arial;color:blue'>This report shows degradation across
different technologies. I would stress that real word performance is the more
important factor as the report concludes… “The triple junction
a-Si modules produce over 15% more energy than BP275(c-Si) does in summer, and
around 8% more in winter…” Yet in the degradation stakes it did
less well.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=4 color=blue face=Arial><span style='font-size:
14.0pt;font-family:Arial;color:blue'>Producing energy should be the first
consideration. 25 degrees C and 1000W/M² almost never exists in real life yet
is the industry bench mark behind which many manufacturers have hidden poor
performance. At realistic temperatures of 50 – 60 degrees C many Poly and
Mono panels only manage 60% of their rating. Additionally, none of the industry
standard measurements allow for a panels ability to respond to light being
captured at high angles of incidence, therefore at times of global irradiance, some
panels performance drops off quite seriously.<o:p></o:p></span></font></p>
