Re: Experimental PV calculator

I think the principle is relatively sustainable, even if the precise import tariff level isn't. In some respects I think Flux will force the other corporations to change how they evaluate SEG. I think the future issue will be as BEV continue to proliferate if they end up having to extend the cheap ...

Re: Experimental PV calculator

I do have to wonder how sustainable that tariff is. Nothing else out there even comes close. It will be interesting too see if it is still around in a couple of years. In the mean time I intend to make full use of it as soon as my solar is installed. Apparently it should not be long now.

Re: Experimental PV calculator

Won't increase capacity any further, heat pump will have to fend for itself, though I am contemplating 200 litre thermal store to charge up from E7 before the heat demand begins in the morning. Would you be better off charging the battery a bit from E7 then using that to run the heat pump instead o...

That's pretty much the conclusion I came to, hence going for the strategy of buying as much as possible then reselling it.

Re: Experimental PV calculator

Whilst financially your probably right, your view may change when you've been up and running for a few months. :mrgreen: I'm a tight arse so I'll probably just go with the numbers ... probably ;) I'm pretty sure I'm not going to rival your setup any time soon! It will be interesting to see how clos...

Re: Experimental PV calculator

Richbee, depending on your tariff optimising for minimum import may not be the best strategy. For example with my flux simulations, I have a very high import and export as I'm effectively trading electricity between low rate and peak rate. This is hard on the battery though - around 400 cycles/year....

Re: Experimental PV calculator

Have a you modelled intelligent Octopus? Charging the batteries overnight on 7.5p and using the power during the day… I just ran a sim using intelligent with my setup. As I don't have an EV, Flux is better. Total yearly bill on Intelligent import, 15p fixed export is £-588 (i.e they pay me £588) To...

Experimental PV calculator

I'm in the process of getting a solar installation and I got bored while waiting for the G99 to go through. To pass the time I thought I'd build a simulator to experiment with tariffs and battery options. It pulls in historical solar, tariff and usage data and simulates a solar installation at 30 mi...
