Re: May 2024 generation
A very different month compared to 2023, over 200kWh down vs 12 months ago. It was poor enough that grid charging was needed on one occasion.
Best day was 29.55kWh (31.29kWh in 2023) - PV still covered over 94% of consumption though, so I can't really complain.

Re: May 2024 generation
I found some interesting data from the Met Office with a long history of bright sunshine hours for different regions of the country.
https://www.metoffice.gov.uk/research/c ... nal-series
On downloading the data for England-Midlands, and after analysing it becomes obvious why our solar panel generation is so variable from 1 year to the next.
May 2024 only achieved 82% of the average from the last 20 complete years.
Unlike the very sunny May 2020 during the 1st covid lockdown which achieved 150%. If only I had solar panels installed then.
Instead I get Dec 2023 at only 52% of average.
