The #Solcast forecast tomorrow looks poor, 10 kWh. The #HomeAssistant automation has set an overnight battery charge to 70%. Looks like we will charging off the grid tonight. Haven’t gone that for a while.
Halfway through the day and we are heading towards the perfect solar generation curve. Let's just pretend it is June and this will happen for the next four month. Unfortunately, it is September.
We didn't quite make it on the last bill. We were 30p short of generating more electricity than we import. The last few days of May were poor otherwise I think we would have made it. @Edent
What a terrible #Solcast forecast today, only 12kWh. This is mad for August!! More like March.
I decided to top up the battery overnight. Hopefully any decent sun will be exported to make up for the overnight charge a bit. It won’t cover all of it, of course. We have spent £1.07 so far today.
I am writing up my first year with solar and battery post. I will post it later this week.

We produced 4441.7 kWh. This compared to the MCS prediction of 3513.38 kWh.
I used the standard unit rate to calculate what that would have cost to import and added the export of 1192.2 kWh which was £107.27. We saved £1592.41. Very happy with that.
FIT tariff has been decommissioned. Now to get my SEG back. Then July can stop being rubbish and the sun can come out again. Ironically the battery has just fully charged and I am exporting 😀
I have posted our Solar Generation and Export numbers for November. I am trying a new format. Let me know what you think. I have also added the yearly graphs for east and west panels.
I’ve just ordered a new 3.2kWh battery. That means we will have 3x 3.2kWh Greenlinx batteries. My installer was having a sale. Normal price £3,500 + VAT. Sale price £2,400, including VAT and installation.
I should now be able to force discharge during the peak export rates. It might be too later for this year, but didn’t want to miss the sale.
