Do feel free to participate in the monthly generation thread (don't be shy). It is important because it puts your own generation in perspective with others. Look forward to any input which will be much appreciated and thanks in advance.

Apart from a breakdown in 2015, it was my worst August (pro rata) ever over the 10 years I've had Solar PV. Dry but very stubborn thick cloud on many days.

But still just managed to make it through with with only 8kWh import, circa 0.88% of leccy power consumed at Nowty Towers.
