Economics of charging at 7p and exporting at 15p

[Moxi]

Ha! can you remember when we used to discuss payback in terms of years!

how the times change

I hope everyone has a brilliant bank holiday weekend and that the sun shines resolutely upon one and all's panels !

£182.03 profit for last month, enough to buy 3 x 450W PV panels including delivery from City Plumbing or 4kWh worth of LFP cells including delivery from Fogstar.

Rinse and repeat.

Impressive Nowty but a little bit too much pink on that import chart
Monthly report - can do better

Yes a bit too embarrassing for me, 3 feckups in one month and quite large ones too.

It does not take much peak rate to wipe out several days worth of profit.

It wouldn’t for us mere mortals that make pennies a day but those crisp £20 daily notes take a bit more to wipe them out. But you’re doing big numbers so feck ups do cost quite a bit.
When I forget to adjust something the annoyance at fecking it up is completely out of kilter with the cost

My first ever month of positive figures also featured some F-ups and 3 days where the Octopus-connected EV wasn’t home so limited to the 6-hr cheap slot.

Congratulations, nice to be on the right side of the line.

Not in Nowty's league for profit but not a bad month for the not so sunny North compared to the sun-blessed south and no fancy import cost graphs either (yet!).
Missing £11.51 of export from the 14th April for some reason.

Surely you have beat me at export and if your import is all at cheap rate your profitability is similar.

I’m looking to upgrade our batteries to take advantage of the import export rates currently available to us IOG users.
I am having our heat pumps/ heating system, hopefully made more efficient, and electrician is looking at adding to our current storage which is attached to our panels on a hybrid GivEnergy system.
He has suggested maybe having a separate system if it can get DNO approval and I’m wondering if this might be better as it could potentially allow me to export whilst also keeping the house warm during the winter. He is thinking about a Fox ess ac coupled inverter and batteries which can be added on to as he thinks this might work out better value for adding storage.
Currently when I export I turn all the heating off.
The plumber has removed the buffer tank and has replaced the 2 heat pumps with a single larger heat pump and he is opening the UFH to one thermostat rather than 6 individual ones.
With our current system I could never have all zones and radiators on, at the same time, as the radiator flow temps were never high enough so some rads never came on and I had turned the temperatures down on the rads as well.
Hopefully this will all work better in the winter
