I see that @majordennisbloodnok mentioned this in @toodles ' thread 'Anyone still weathering it out with Agile?' 

I assume that other energy providers will follow suit, I've been a happy customer of Octopus for the past 3.5 years and being on Cosy and the fixed export rate has worked well for my setup (Flux was great that first summer due to the high rates, but has not stacked up for me since).

I had assumed that this new market tracking export tariff would be similar to the Agile export tariff which most of the time (when I've checked it/I'm not an expert) seems to be below 15p.

So I'm interested to hear other people's views and opinions of what might happen.

Where did you see that?

My understanding is simply that Octopus Outgoing is no longer a fixed tariff, but is now more like a standard variable rate tariff for outgoing, currently still at the same 15p rate as it was before. The only difference is this rate is no longer fixed for 12 months but they can change the rate with whatever notice is required. I assume they may change the rate quarterly to reflect the current market.

Longer term, there may be a shift towards more dynamic export rates where they pay less during the day when solar is abundant and more at peak rate times when demand is high, but that is pretty much  what Agile does on a daily basis. I can see it moving to an export rate of 8p during the day with a peak rate of 16p, which is kind of where the average on Agile outgoing has been over the last year.

Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.

@old_scientist Thank you, that makes sense and I've re-read the email just now and it aligns with what you say.
