April 2023 Generation
Re: April 2023 Generation
April was a bit of a changeable month, some superb days with mild dross in between.
Still, generation ticks upwards and grid import was restricted to the little import you get when the inverter is a little sluggish to react.
The big change for me was the changing over to a bigger DIY battery bank, perfect for soaking up more generation.
Combining that with a very cheap upgrade to a 6kW Solis inverter means there's a lot more scope for more relaxed self-consumption.
Heating via gas was replaced with direct electric heating but a heat pump and UVC are definitely on the list for summer.

Re: April 2023 Generation
Nice fancy spreadsheet MrPablo! I might crib off that and make my own like that
Re: April 2023 Generation
Total generated 832.5kWh
Low 8.4kWh
Average 27.7kWh
High 48.1kWh
41% consumed by house, including EV charging
32% went to Powerwall
27% went back to grid for FREE
648.8kWh from grid, mainly overnight EV charging
94% to house and car
Only 6% to battery (hmmm, interesting, think I need a bigger battery!)

Re: April 2023 Generation
April was a good month - 528kWh generated, against a PVGIS estimate of 490
However still imported 140kWh and exported 190 kWh - hoping I can reduce both import and export now that my 2nd battery is installed and working

Re: April 2023 Generation
North Wales west faced array 360kWh for the month plus another 42 for the mobile array's - plenty for us to be able to direct some free electric to the EV as well as keep the house batteries topped up.
Annoyingly my electric supplier just wrote to me to put the DD up based on my consumption ? I have adjusted it down by the allowed 10% and after this months payment I will call and ask for 50% of my credit balance to be returned to me so that I can benefit from the interest it will earn rather than them - I read this week that the big six are holding around 7 billion pounds of credit in their accounts - and they talk of "gaming2 the system ?
Cheeky so and so's

Re: April 2023 Generation
343kWh, but it was only half a months worth. Next month onwards might be better..
