Pleased with that balance so far.

Figures for April from myEnergi Zappi (smart meter and FiT meter stats are slightly different so I will stick with the Zappi figures for consistency)

Generated: 698 kWh (last year 754)
Self consumed 577 kWh (645)

Total Consumed: 808 kWh (na)

Imported: 231 kWh (416)

Exported: 117kWh (109)

I was very surprised at how much import dropped year on year. I would like to think a big chunk of it was from my audit of standby consumption. In theory it could have been in the region of 2.5kwh/day but some of that would have been covered by solar (hence the lower self consumed figure). I was also testing out my 2.4 kWh PPS/340w solar panel to time shift but not every day. I also did more car charging from solar (despite less generation) not worrying if other devices were operating at the same time time rather than importing at cheap rate overnight.

Not got the solar or batteries installed yet so we decided to try some usage techniques to see if we could use less power and it's been pretty successful.
By simply switching everything off of standby, using the shower on eco mode and not using multiple devices to cook with we've gone from an average of 12kw per day to 9kw per day.
It's taken no real effort and is quite addictive now we have a new target.

April stats:

Generated - 767kWh (108% of PVGIS) Consumed - 373.3kWh Exported - 355.7kWh Imported - 18.5kWh Figures don't balance exactly due to some losses. Gas 232kWh compared to 945kWh last April. Saving roughly £95 for the month. Hoping to significantly reduce gas usage in May.

April a good month for me, 11.3% over PVIS ...

344.4 kWh Total used
29.3  kWh imported
477.5 kWh generated
136  kWh exported

70% of generation used... 

PVIS 429
Best day 25.03 kWh
Worse day 8.1kWh

Gas usage almost zero... still using my AC if any heating is required in the evening.

Well done that is a very nice low import figure.. had to change the bath mixer taps as they were only delivering cold water...so the electric shower has been in use but still happy with my numbers

Impressive SEG rate on Octopus Agile Outgoing. I was looking at getting a battery but if outgoing rates move up nicely with wholesale costs it significantly weakens the “man maths” for the battery. Did you have to do anything special to join? I am lucky and on a fix until 29 September, but with a different supplier, and was thinking about a move to Octopus at that point. With that huge export rate, instead of saving 24.5 per kWh not exported I’d be saving 13.5p at current price caps. If energy prices do fall longer term the battery economics suffer too, even if that SEG payment also goes down. This doesn’t take in to account the (maybe somewhat irrational) frustration of exporting energy you generate of course… Wonder why more people don’t go for Octopus Agile Outgoing? Is it just they want to be on Go?

Nothing special needed, I joined Octopus when Utility Point went bust, they installed a smart meter a week later then had to wait for the export MPAN to be generated and that was it. 

I'm on a standard variable tariff, I think the only two tariffs which are in compatible with Outgoing Agile are Go and Go Faster.

Super, I think you’ve just pushed me over the edge of not getting a battery - as much as I irrationally want one! Solar is a solid return (even without outgoing agile), and definitely environmentally friendly - battery case is still borderline and relies on a lot of assumptions
