Kent, much sunnier than Scotland
A rather poor day today, much worse than forecast, just 18.68 kWh, actually exported more than we generated at 18.8 kWh.

Today's electric should just be negative, yesterday was -£5.37 including SC.
We had two days this month where electricity cost money, Sunday which was 60p and 3 April which cost 35p, this months electric should be about £47.42 profit depending on today's cost.

Total for the month is 907 kWh, compared to last April which was 966 kWh, next month will be over 1 MWh (last May was 1.325 MWh)

Total for this year so far is 2031 kWh, 1070 from the SolarEdge system and 961 from the garage array.

We were doing well until around 4ish when the clouds rolled over. Still, another new record today, just pipping yesterday:

19.9 generated with 10.32 exported

And for the month:

362.9 generated and 159.04 exported

Looking at the local forecast we'll have to wait until next Thursday for any more real sun, though I'm sure the forecast will have changed by then anyway! :)

51.1 generated and 36.2 exported.

A record day for me. I knew there was a 50 in it if we actually got a clear day! Not quite a perfect day as it clouded over for half an hour or so in the afternoon, but the nearest to it so far.

834.0 for the month against a PVGIS target of 827.2. 535.2 exported with 189.7 in the peak window. Imported 56.8 with 31.5 at the cheap rate.

Cost for the month -£63.93. :)

Located in loft and all cables there. I’m thinking of running a single plug off and doing the fan. It def crashed due to heat but was responding on the front. I’m just wondering as we get into serious heat it will fail. What about mini USB powered fans? I think a big fan on speed one on a wifi plug might be the solution.

Also solar was only fitted at end of March.

The work will be guaranteed, unless you fitted it yourself. Might be worth a mail to the installers. You shouldn't have to workaround problems like this.

21.4 kWh today. Only 0.2 off my single day record

Bad month again in Coventry. 303 kWh with an installer target of 390. 5th month in a row under installer target. Not looking good for the start of May either.

13.8kWh with 3 spare panels where I was deciding where to place. Now found an ideal spot for April to October inclusive so just ordered some more Van Der Valk ballast system for 5 panels (plus an additional two panels- this should take me to 15.75kWh).

Mega install. Should do you 15k units PA.
