Capacity Orientation Slope Lat Total kWh/kWpk
3.15kWpk 157.0 11.0 50.9 175.1 kWh 55.6
Hot on the heels of the worst September, October 2019 is also the worst since install in 2010. 2012 was close at 177kWh, by contrast 2018 was 253.6kWh (44% higher!)
Have checked the system and it seems OK, just been a really wet and overcast month.
