July 2011 PV Results

A hot July ends and it has been a good month for our PV system. The very hot weather has had a very real decrease in our output, but the sunny long days has still been good for overall production. I counted 7 days that were either "pure blue" skies, or virtually cloud free other than the odd passing cloud. Many more had occasional cloud passage. However, we had many days that were 30 deg C and this hot weather reduced the peak output levels. I'll post examples of those soon.
Below I am providing the raw daily totals for July. The days with 30 or more kWhrs were virtually cloud-free, and you can see the number of days over 25 kWhr is also high. Only 1 day [28 July] was low - a cloudy day with even a bit of rain which was much needed.

The next figure shows the total daily production since we started. Despite the longer days in July compared to March, total daily output is trending down to 30 kWhr from March's 35 kWhr.
