March 25 - Sunny oh yes

Well I have had 3 Months of March and panels,
2023 294 kWh
2024 339 kWh
2025 572 kWh

amazing, but I only have 3 years data.

Yes, I sold back to the grid every day in March

No solar panels myself but keep up the good work , starting to see the extra solar generation coming through to lower agile daytime prices.

Yeah, that’s why Octopus have reduced my daytime export prices by 3+pence /kWh starting today, out of my pocket to yours. However I don’t think my 18kWh will go round to everyone 🥴

Yep, 92KWh exported during March, 37 percent up on last year.

Also means less imported from the grid of course because I've had a full battery charge by lunchtime most days.

Or perhaps simply its been fairly windy last few days.

Lower solar export rewards perhaps an inevitible consequence now thst UK reaches an even higher - possibly too high in some locations  vs local grid demand ratio - level of solar installations - as 100,000s installed since 22 crisis pricing.

If say empty homes use say 100W max on average mid afternoon - you need 37 of those to use up a typical just sub 4kWp - 3.68kW iirc at 230V - 16A per phase - basic G98 cap.

The problem is we are now -  at 1.4m installs - over 5% -  one in 20 not nearer that 1 in 40 demand level.

Locally in I suspect wealthier suburbs / regions and no doubt weighted to sunnier south - probably much higher than 5%.

As it is DNO teams have been actively having to manually adjust some local final stage distribution transformers to cope in recent years.

We're not quite there yet  - but the local generation vs need imbalance - the very reason why export is far more heavily capped in some markets.


The future imbalances are difficult to predict - but it's easy to imagine scenarios where local solar not attracting the export premiums it has say from 9 am -4 pm.  But on the other hand others when it might command evrn higher rates say more to reduce peak demand 4-7 pm.


And grid level solar and wind - regulated and so controlled - and all too often at times compensated not to generate - £1bn last year - £30 per domestic and small business connection - are likely going to be given natural preference.

You can already see that happening, Octopus Flux has cut the day rate by 3p per KWh but increased the peak rate by 3p.

Well they put all the import rates up by 6.8% approx and the peak export by similar , but dropped day export by ~26%

Is that 26% the same 3p ?

Yes, from the previous thread I think it is.
