747 in April 
Last year was 626
Mind you it was very sunny this April - unlike May so far.....!

500 for May about 60 up on usual

431 here in Surrey, which is also spookily 60 up on last year!  (And we have passed our 5 figures mark - huzzah! )

 Not sure how this compares with last years as I was unable to take a reading

 I guess it is quite dismal as May seems the have been the coldest wettest may we have had here this last ten years.
 Lets hope this forecast heat wave arrives and stays for even the melons in my glasshouse are starting to suffer from a very very slow growth .

470 produced here against forecast of 438......so quite happy as the month started very slowly!!

Our inverter is playing silly b*ggers at the moment - it is fluctuating wildly on the Grid side voltage readings - such that it reaches its safety limit of 265v and then shuts the system down, for it then to have to go through a  3 min restart process. It has been doing this scores of times every day since 25th or so of May.
We thought it was to do with Western Power (our network provider) so I called them, telling them our inverter was telling us the grid was overrating all the time. They sent a couple of engineers who tested the grid side and recorded a steady 244V while the inverter was saying it was busily varying between 254 - 261V...
We have therefore contacted our installers for them to come and see what's what

If the inverter is faulty  it might be worthwhile getting a historic  print out of all local lightening strike withing 1,00 mtrs of your property .
 We thought that the board supply had been given over voltage damage  but in the end after five months of careful conversations and talking to lots of interesting weather folk & electronic engineers we got a very reliable satellite mapping print of all lightening  strikes and formations over the week in question.. that helped an awful lot and recouped us some £3.5 K under insured lightening stike terms of the domestic  policy .

As soon as I presented the mapping to the insurers they coughed up prior to that they obfuscated in every letter ,  saying it was not a valid claim as no one else in the area had claimed .

Thanks Clodhopper I'll have a look into that.
The Inverter people are coming to do an upgrade on the software on Monday - apprently that helps....!

400 for June.

That's not very good is it?  Most of that was probably yesterday!

475 for us in June, almost identical to 2014.

Yesterday's generating rate was amazing  I checked it on the webcam to see what a sunny afternoon would look like & was very happy to see 5.9 KW between 14.15 to 15.17 hrs

Managed to get 489.5 in July from the forecast of 437. Thee extra units will hopefully continue to reduce the payback!!!!

480 for June 40 up on last year

717 for June 2015 compared to 985 for 2014.......
This is all down to the inverter shutting down every 5 minutes when the sun is at its hottest because of the Grid overvoltage rating situation.
We've had our installers out a couple of times, they've taken lots of readings and been in discussion with Western Power and Samil (inverter manufacturers)
When the Grid voltage reading was hitting the 260v mark we switched on kettles etc to see what happened and yes the Grid Voltage reading would drop to 253v or so. LC said that it might be because we are at the end of our supply line and there's not a lot of electricity requirement from our locality during the day - up until Feb we did have a neighbour who ran a chocolate making company and had deep freezers etc running so the power requirement was higher - but they've left. In addition the people who have moved into their house have just installed their won PV array so potentially our problem may get worse
Samil suggested they changed the settings so that the upper limit (265v) was increased before the inverter shut down but ZLC said this was not acceptable so Samil have agreed to a new inverter - which we now have ready to be swapped over next week hopefully.
Gutting to lose nearly 300kw generation in a month
