Looking more closely at the the stats . . .
- 12 solar panels on the roof of the house (all made by LG)
- Total generated 3.01 MW-h
- Individually the panels averaged 257 kW-h over the year
- The top performing panel generated 275 kW-h and the poorest 231 kW-h
Our best performing day for solar generation was 28th May 2019 when we generated 24.24 Kilowatt Hours (kW-h), with the month of May being the highest month for overall solar generation. Below are the Top 10 and Bottom 10 dates for solar generation throughout the year. It should be no surprise to see that many of the bottom 10 dates are near the shortest day of the year.
Date | Watt Hours | Date | Watt Hours | |
28/05/2019 | 24,235 | 15/02/2019 | 50 | |
04/05/2019 | 23,822 | 23/12/2018 | 102 | |

20/06/2019 | 22,760 | 15/12/2018 | 261 | |
05/07/2019 | 22,729 | 29/12/2018 | 304 | |
03/07/2019 | 22,720 | 31/12/2018 | 316 |
The table below shows the electricity generated by the panels - the figure in green is the resulting reduction in our monthly electricity bill. Much of our surplus generated electric goes straight into the hot water with the rest being fed back into the national grid (a back of the envelope calculation estimates this as being an average 47% of the energy generated).

And of course there must be a graph!
Looking forward to seeing what the next 12 months generate . . .
