Looking for VRM data for a south UK grid connected ESS with south facing PV?

I am trying to run a calculation for assessing the import and export demands of an existing system which has had continuous changes to it making the data unrealistic. To allow is calculation of what the correct set up needed for the house, I was wondering if anyone on the Community is from the southern end of the UK, has a ESS system on a south'ish facing PV system. The most important element I need is the PV generation for a 12 month period. If you have your system data accessible on VRM world, even better as I can carry out a basic real time comparison.

I am in South Devon and have what you describe (but not 12 months)

I have been amazed at the day to day variability (in summer)

I have an installation in S Devon, 16 x 230W panels facing due S installed in 2011, no noticeable degradation so still 3.68 kW nominal output.

The last three full years' figures are 2019: 3926 kWh, 2020: 4043, 2021: 3967, is this what you want?

The last five days have been pretty consistent
