I'll summarise some more stuff end of May as I'd then have one full month on Flux, but for now I'll put down some initial thoughts after just a week or so.
I moved to Flux from Go on 20/04, so today is day number 10 of being on Flux, a long enough time for some sort of feedback on how it's going.
My bill from Octopus encompasses 20/04 - 26/04, so exactly 7 days.
Import costs:
Export profit:
April has been pretty decent weather wise, and I can see from my generation stats that those 7 days were fairly decent, with 122 kWh of generation across them.
Even so, to have my bill for electric be negative in total, I am very happy about that outcome. I hope the next 4 months is similar, for me solar has always been less about making profit and more about just cutting my bills as close to zero as I can, whilst using green energy to do it.
On Go this would have been cheap, but not negative. With decentish weather my average Go price is around £1/day.
Pros and Cons really boil down to a couple of things, but the main pro is that with Flux I don't worry about exporting being wasteful anymore, or trying to min/max the battery SOC overnight to guess at how good the solar may be.
The main con is that with Go I would just find ways to use the excess energy efficiently, but I now have an opportunity cost instead, for every kWh I export, the cost becomes the money I would have been paid for exporting it.
The biggest con so far is that I am discouraged from using much in the peak window, this sort of forces me to consider cooking food earlier in the day, before 4 is a bit earlier than I'd like in reality (ideally if peak rate was like 16:30 or 17:00 start that would be preferable.
