Solar Yield : Degradation and % Efficiency

Simple chart for Azimuth/Inclination and percent degraded yield from PV's used for sloped roofs: based local in Israel (A Google login required)
be sure to check out GreenTops site for more information

 Timelapse animation of a system we've installed in Elad, Israel, which shows the preperations, modeling and the last part shows how we evade the shadow. we've used a Trimble D-GPS to obtain ~1 cm resolution of the building and high walls that we had to take into consideration.
Your comments are most welcome
Do You wish to compare the yield of Your system to other systems? 

I'm working on a daily kWh per kWp installed on systems around Israel, you can monitor hundreds of systems using the JavaScript I'm working, the graph charts are in this link
there is about 10,000 kWp monitored daily that You can view how systems in Jerusalem yield differently than systems in the Golan, in cities or outside of them etc'.
if you like to be part of this statistics please inform me and I'll log Your system as well.
Thank You for reading this, Your comments are most welcome !
