When I first joined Octopus at the beginning of February I opted to join the Octopus Tracker tariff.
My solar and battery were due a couple of weeks later which is when I would look to join Agile.
However I’ve been confused by the fact that Tracker has been better value than Agile consistently. If they’re both based on wholesale prices, shouldn’t they average out evenly?
I too use Tracker for import as well - similarly noting that if I was on Agile I would not benefit. Even if I maximised filling batteries at night I don't think it would help enough. Very much depends on setup & usage I guess:
8kw pv solar
5kw Hy Gen1 inverter
3 x 8.2kw batteries
ASHP
E/V
EP
Tracker will need watching in case anything changes but consistently since 1 Jan 2023 has probably averaged around 22 or 23p.
As a separate matter... I'm on Standard Fixed (15p) for export as much of my export is forced when batteries are full and excess solar produced. Agile export at such times are typically under 15p. To manage export on Agile would seem impractical and for little benefit.
I only have 4kw of pv solar, but am also on the fixed 15p export tariff.
My excess solar after the battery is full usually happens in the early afternoon, and then my battery takes over during peak times.
In effect I've not used the grid for 2 days now and have exported 10kw.
The other big thing about the tracker is the gas, in effect this has halved the price I was paying before on the standard tariff.
