I am writing up my first year with solar and battery post. I will post it later this week.
Headlines
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.
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.
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.
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.
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.
@bazcurtis I'm working on a 75% weighting with +2kWh buffer. Mostly it exceeds the estimate, but it's far better for me to charge overnight just incase, particularly if the EV is on the driveway to soak up the extra.
Overnight is cheap, and we're still net consumers in any case, so I'm paying 9.5p for juice rather than 30p
