No good with phone screenshots and webpage seems different but here are my figures from the phone for june
pv prod 1250.5
to load+batt 351.7
to grid 898.8
self consump 28%

load consump 347.6
from pv +batt 340.8
from grid 6.8
self suff 98%

Here is my image for the month of June
I calculate (as does your ROI sheet you should have been given) from the bottom two values
PV Production 1250.50 kWh (772.40 kWh)
To Load & Battery 351.70 kWh (384.60 kWh)
To Grid 898.80 kWh (387.80 kWh)

To Load and Battery 351.70 kWh @£0.2443 import cost using my rates = £85.92 (£93.96)
To Grid 898.80 kWh @£0.12 export at flat rate Octopus export = £107.86 (£46.54)

Totals £193.78 (£140.50)

I suspect you are going to do well with your system, and smash £1200pa.
My first year ROI was given as £1195, and I achieved £1243.42

A bit cheeky of me (sorry team if this is) for adding my personal link

But you could supplement your income to help your ROI by joining Axle energy.

You get £25 by signing up, and at least £10pm minimum, so you gain £120pa at the very least.*

* Even if you had to buy your electric in to top your battery up @30p kWh, you can sell each back for £1 kWh and you get your export rate from energy supplier on top.

Do you still get your suppliers export tariff in addition to the £1/KW from Axle?

Yes anything you get from Axle is on top of your export from energy company. Octopus have just launched a similar product for customers by the way.

Since April I've made £62 from Axle. My export is limited to 5kW.
