June’s Solar Generation and Export Numbers
Here is the overview for June 2023. June was again another improvement. 80 kWh more than May. We lost our export tariff a few days before the end of the month due to an issue with our old supplier E-On Next not cancelling our old FIT tariff. Very annoying. This report will not reflect that, the figures will reflect we were being paid to export
I added a three Home Assistant sensors to record the maximum watts the panels were producing. I was really interested to see the maximum of both roofs as the sun reach its highest point.
The worst generation day was the 28th with only 10.7 kWh and the best was the 13th when 32.4 kWh was generated.
The best export day was the 9th with 16.7 kWh
The graph below is the total generation for June. Some of the battery came from the Octopus Agile overnight charging. More on that at the bottom of this post.

Octopus Agile
The costs shown here do include the standing charge. Any comparisons are compared to the until cost if we were not on Octopus Agile, which is 35.06p per kWh
For the month of June the average unit cost Octopus Agile Import was 18.84p. The average unit cost Octopus Agile Export was 9.75p
Our best export day by cost was the 21st with £1.87. The average Agile export rate for that day was 11.57p kWh
Our electricity cost from the grid for June was £22.51 compared to £32.16 on the standard tariff, this is a saving of £37.82 comparing Agile to the standard tariff once the export is also added
The solar generated £257.06 using the standard until rate of 35.060p per kWh
In total we exported 290.70 kWh and made £29.42
We did not charge the battery from the grid at all in June.
The percentage of our electricity generated by the solar panels for June was 159%. We generated 733.20 kWh compared to the house consumption of 461.80 kWh. Some of that house consumption includes the Solar iBoost. That used 31.21 kWh of the solar we produced.
The best profit day was 21st. We made £1.35. Import cost was 53p, the export was £1.87
