PV/day

This first chart below shows the daily solar PV generation figures (in kWh units) taken from the Fronius inverter.  The yellow area shows the predicted monthly average per day.  The red line is the actual average for that month (so far).  The grey dotted line is the predicted average for the year on a daily basis (9.5 kWh/day).

This next chart below shows the solar PV generation figures for every half hour from 8th July to the previous Friday.  Each "bell-curve" is 1 day's generation, the taller and fatter the better.  Shorter peaks mean the power generated has not reached as high a level.  Thinner shapes mean the peaks have lasted for less time.  

The figures are logged on the USB memory stick in the Fronius inverter.  Sadly I didn't realise this could be done until we'd been generating for more than 7 months!

As you can see the first week in Sept has been the best week so far, during the data-logging phase - the best since the start of July.  Late July & early August weren't bad, but there was never a period of more than 3 good days together.
