Octopus (the grid) is my battery

Andris · 2024-04-02T15:48:19Z

When i got my pv I decided against battery storage for many resons... space, cost, investment return, one day recycling the battery etc... I have a 16kw heatpump and a 8.4kw solar but no battery. I was dreaming of a scenario where my export would pay me more than my import tariff, so that i can use the grid as my battery. After trying many different tariffs for import and export, i found the best combo for my house and my setup so far. I am on Octopus Agile (last two month averaging 12.3p/kw.) For export I am on outgoing Octopus fix (15p/kw). 🙂

@andris And that of course is just as it should be!😉 I feel hard done by if I have to pay as much or more than the export rate of 15pence per kWh! The differential at present is not worth charging up the battery so as to export energy during times of peak demand at the moment - allowing for the 10 % round trip loss, anything over about 13.5 pence means I leave the grid power alone. 😉 Today’s solar is dropping rapidly now (19:00) but our system has produced 40 kWh and of that, 31.5 kWh have been exported.

@andris My ‘Best Effort’ so far was on 4th. June 2023 when the production was 51.5 kWh. I have 8.1 kWp across a total of 21 Canadian Solar panels, each with an Enphase IQ7 microconverter. I do have some shadowing, and placement is not ideal but the best achievable in the circumstances. Regards a very green Toodles in Berkshire.
