August 2018- 453 kwh produced from PV
August 2018- 171 kwh electric bought
August 2018- 5 kwh gas bought

4.8 Kw of batteries went online 1st Sept, interested to see how they will adjust the figures and relationship between the two power types. Happy Days! :)

2014 418.5 kWh
2013 491.3 kWh
2012 393.9 kWh

12 months generation to the end of August 2018 was 3781.1 kWh (984.7 kWh/kWp)

Total generation: 396.1 kWh 100 % of PVGIS (shaded) prediction.
Generation per kWp: 103.2 kWh
