Best 2 days since install so far, 35.7 kwh yesterday and 34.4kwh today. Roof slope is quite low, so looking forward to more of these from now on!
Diverted 14.4 kwh and 11 kwh into a storage heater via Eddi (the type with the bricks that holds heat for ages, 2.4kw input, will accept approx 17kwh to fully "charge"). It heated the bedroom area (north of house) yesterday evening and was still releasing heat when got up this morning, so finally able to keep oil off completely (it doesn't need a lot of heat to take the chill out of the nights these days)

24.7kWh today. Used nearly all of it, exported only 1.2kWh. Dumped a few kWh into the oil radiator again and avoided the boiler too.
@connesha Tell me more about that storage heater on the Hints, Tips and Troubleshooting thread please. Is it an old one that was already in the house or did you buy it new for the purpose of dumping surplus PV? Better job than the oil radiators for sure, but they seem pricey.

Three very nice days here in Dublin. Got a little overcast there about 2pm today, but we'll take it as a win.
Tomorrow is looking a bit down on the previous few days (but still decent) and then Tuesday we're back to blue skies again as far as the forecast is saying.

Great day here too. Gave 8 back to grid but consumed 38kw of it. Looking forward to having more than my current 5kw battery eventually. My seplos landed in Ireland today from China so just need batteries to land next and won't have to worry too much about export and definitely not of import 😃

I promised to put my own "simple" excel solution to show the Radiation Graph from Met.ie. Below is the spreadsheet and how to use it.
Get your actual location from Google maps (Right click on your location) and update them in the link below.
http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast?lat=52.866920;long=-98.265114
Book mark the webpage for future use.
Right click in the results and “Save Page as” “locationforecast.xml” in C: \Temp
Open the attached spreadsheet “Radiation Import.xlsx” which can be stored anywhere on your PC.
Click In the Graph area in Tab “Pivot Chart” to activate the “Pivot Chart” option in the menu bar, and from the menu bar select “Pivot Chart Analyze” and then “Refresh” and “Refresh all” from the ribbon.
A graph like the one below is displayed showing radiation and cloud cover for your location for the next ten 24 hour periods (hourly for first three 24 hour periods, and then 3 hourly and 6 hourly for the remaining periods).
If you want to change the file location for the input file, firstly tick the “developer” option to add this to your menu (File-> Options -> Customize Ribbon and then Developer option in the right hand box).
Then select the “Raw Data” Tab.
From the menu bar, select “Developer” and “Import” on right of ribbon
Above used Firefox and Office 365

26.1kWh today, 392kWh month to date. PVGIS-SARAH2 v5.2 estimate is 402kWh, and will easily beat that tomorrow.
Have been essentially off grid (both electrical and gas) since the 18th March. The low house base load means that the 5kWh battery is consistently getting us through the night. Would still like a bigger battery to get us through the dull days though.
Have really been struggling to use the generation today, as you can see below; EV charged, 250L of 60°C water in cylinder, and enough to keep house heated with oil radiators too.

God dam it! 39.3kWh thought I would break 40 for the first time ...as Mp3guy I'm in Cork and not a cloud in the sky. But there must have been some hight level clouds or hazy as I never hit my 6.1kw max. I should have been topping out at 6.1 for an hour or two but was less than that. Ah well but as someone said yesterday that's a serious sexy curve....Kate Upton or Dwane Johnson whatever floats your boat. I want to be as PC as possible... 😀

Those numbers are phenomenal. 73Kwhr, 39Kwhr. Awesome. I feel a little embarrassed to lob in my 18.7Kwhr. Nearly equaled my previous best (18.9Kwhr)
ECO yeah, some kind of high altitude haze as previously I broke 3Kw when I did 18.9Kwhr, but only 2817w today.

God dam you high level clouds😡 another day at 39kWh....I should be topping out at 6.1 for an hour or two at least with the sun shine we got today. At least I had a great day out on my patio with my mam and dad (85 and 87) and drank a bottle of Powers with my Dad (I know it's mother day...but she's a pioneer for 80 years+) and had a great laugh.
Rock on summer
