Octopus Outgoing vs British Gas - Who will pay me more for solar generated electricity?

Netexporter

My system is 3.68kw or something thereabouts.

That's the inverter output limit allowed for a normal G98 connection. You can have more panel capacity but that is the most you can export. Normally arrays are about 20% above inverter capacity, as the clipping in ideal conditions is outweighed by the greater average export the rest of the time.

I am currently with Octopus for my energy supply.
However, I have British Gas paying my Feed in Tariff for the electric generated by my 4kw solar panel array.
Looking at my last FiT payment, BG are paying me £22.53/kwh for Generation and 6.79p/kwh for Export.

22.53p/kWh, not £22.53?

6.79p/kWh for export, but "deemed" export as 50% of generation rather than metered export?

Last 3 months we had 828kwh Generated = £186.55 and 414kwh Exported = £28.11

That would be consistent with deemed export.

Do you have a smart meter? Do you know how much electricity you actually exported in the past quarter?

My question is, would Octopus Fixed or Agile pay more? I can only see details of the export tariffs on Octopus website nothing about their Generation payment.

Outgoing Octopus (Fixed or Agile) replaces your export payment.

So, you can:

1. Leave your FIT with BG. Claim geneartion and deemed export as currently.
2. Leave your FIT with BG. Claim generation but out out of export payments. Sign up with Octopus for metered export on one of the Outgoing tariffs.
3. Move your FIT to Octopus. Claim generation payments from Octopus (at the same rate as BG are paying) and metered export on one of the Outgoing tariffs.

But without knowing exactly how much you export, it's impossible to say for certain whether you'll be better off with metered export or deemed.

Thank you for this superb explanation @QrizB. I thought you had to cancel your entire FIT agreement, not just be able to switch the deemed portion. 

Just read my meters, and compared figures since I had Smets 2 installed in July 2020, so let's call it 3.5 years..... 

Solar generated = 14098 kwh
Therefore deemed = 7049 kwh (@4.82p)
Actually exported = 11514 kwh

Wowsers.

Already on the Tracker Tariff with Octopus, so I guess switching this is today's job.
