Groar, how has your PV installation been doing during the summer months?

Thanks to wake me up
Just added June to August production figures in post #8. As you can see in posts #8 and #1, the best production was in June : the days were longer and cooler.
Nowadays the inverter is starting later and stopping sooner
As the longest day is 21st June, today is equivalent to a day of beginning of April except we have lesser clouds and hotter temperatures.
While end of 2008 had a deficit of sun, 2009 summer has too much sun (+15% for last 3 months), a deficit of rain (only 50% of average for the last 4 months and 2 rainy days during last 4 weeks), with hotter temperatures (2-3 °C over average, which is much more at panels' level).
My current forecast for the 1st year of production is 15% under the initial forecast
If I had to install another solar array on my house, I would install it toward East (so they are producing when it's colder) and I would use panels less sensible to heat.
Happily the solar panels are only one of our tools to be greener and lowering consumption is another one : the current forecast for this year is 20% under last year consumption
