Pretty mediocre month

April

Was May any better?

That is May, thanks for pointing that out!

Looking to join in.  Finally had the batteries installed just over a week ago and it has made a huge difference.  
Grid import is sitting at a total of just over 5KW.  Still waiting for the paperwork for MCS and DNO notification.  
Have exported 980KWh to the grid for free since installing the solar panels at end of Jan 22.

May another good month for me, 5% over PVIS ...

Every months so far this year has exceeded PVIS

Is that from Sunnyportal? It looks very similar to mine, but I don’t have a yield expectation. If it is, any idea how I can get the yield expectation on there?

Edited my post .. its PVGIS NOT PVIS...

If you enter your details it will give you an estimated generation, this can then be typed into SMA Sunny Portal

Thank you. I can’t seem to get it to work. It’s a bit confusing as under my system info it does have an estimated generation (“annual production figure”) , but it’s not showing the grey bars. I don’t appear to be able to edit anything - guess it was setup by the installer

Its under Annual comparison, edit prediction values

Hmm, looks like I don’t have that option - maybe I don’t have an “admin” login. I can compare outside in Excel I guess, doesn’t matter much.

I have an excel sheet as well as I had some missing data that couldn't be recovered... TBH its now OOD as it was Feb 2021 so I don't see it anymore !

just going to add to this as i had my solar / battery installed mid may - i started taking manual meter readings as i have changed from british gas to octopus....

since may 18th i have used 16kwh of electricity and 8 units (whatever they are) of gas - i went a whole week without using any of either

History for 2021 here.

History for 2022:

• January 2022 - 219kWh imported, 84kWh generated, 17kWh exported.
• February - 169kWh imported, 142kWh generated, 51kWh exported.
• March - 146kWh imported, 246kWh generated, 99kWh exported.
• April - 132kWh imported, 300kWh generated, 179kWh exported.
• May - 106kWh imported, 335kWh generated, 171kWh exported.

PVGIS thinks June should be my highest-generating month of the year, which seems a reasonable expectation; it's not that much better, however, than May or July (301/313/309kWh for M/J/J respectively) and sometimes they beat it. How did June do this year?

• June - 40kWh imported, 338kWh generated (124.3 O's, 108% of PVGIS), 114kWh exported (34% of generation).

Import is way down to 1.3kWh/day, thanks in large part to my additional battery capacity. It's also worth noting that 18kWh of that (ie. nearly half of the month's import) was on three especially dull days when I failed to charge my battery.

Self-consumption of 224kWh (7.5kWh/day) is also improved on last month and total export since installation of my smart meter is now only 47% of generation. The lager battery has helped with both.

Compared to last June I've imported 52kWh less (thanks battery) and have generated 32kWh more.

My latest Octopus Go statement shows June-ish consumption of ~36kWh off-peak and ~17kWh peak, for an average price of 8.4p/kWh, which is (again) not quite as good as last month.

On the whole I'm quite happy with June

... although if it hadn't been for those three dull days my import would have been well under 1kWh/day!
