The energy price rise is very disproportionate. Probably aimed at getting us to switch to air source heat pumps. My next boiler maybe oil fired. Electricity rate 21p to 28p/kWh up 33% Electricity Daily Standing Charge 25p to 45p up 80% Gas rate 4p to 7p/kWh up 75% Gas Daily Standing Charge 26p to 28p up 8% I've got a log burner and oil heating. Oil is around 60p litre just now, march 2020 when covid hit uk it went down to 20p!! Shouldve bought drums of the stuff. Logs are around £120 per ton bag. As electric and gas increase and people try to find alternatives, these usually increase in price aswell. For those staying long term in the same home, solar and battery storage seems a logical way to go self sufficient to a degree.

I am that man with Solar and battery..
my system is rated at 4.2kWh.
system installed in September 2019, over a full year it produces 50% more electricity than I use.
in October I could about manage, November I get about 50% of my usage, December about 25%, January 33%, February 60%, March all my usage,
Of course this would be better if I had a more southerly aspect to the roof.
Battery is great but 2.4kWh of storage costs about £1000. I will be increasing my storage as even in January I have days when I export to the grid and end up buying the next, and indeed in August last year we had a few very dull days in a row and my storage slowly depleted.
at the new higher rates of 25p plus per kWh then ...
I Use about 2000kWh a year
since September 2019 ( 28 months ) 2.3 years ( so call it 4700 kwh usage , probably low as includes a 3rd winter )
I have Imported 2100 kWh I have exported 3800 kWh
Most of my import has been on cheap rates ie at 6p kWh or less most of my export has been at 5p or more ( Average is actually 10.8)
So I imported 2100 but used 4700 so I would save 2600 units @ 25P a saving of £650 ( Plus VAT ) I have exported 3800 @ average 10.8p £411 the 2100 imported has cost me just over 8P a unit so saving 17P a unit another £375
So I have saved £1418 in 2.33 years, just over £600 a year
I think a reasonable return on a £7,500 investment

Need to stop all this whining about the planet and throw up a couple of nuclear power stations. Preferably in Wales where the population density is low.

Down a coal mine? Actually the part of Wales I live in has a dense population ( Well some of them are very dense ) and we have a disused coal mine nearby. I don't understand why there is no proposal to extract heat from the water in these mines and pipe it round the area.

I am that man with Solar and battery.. [Snip] So I have saved £1418 in 2.33 years, just over £600 a year I think a reasonable return on a £7,500 investment A (probably small) omission is that your usage while generating didn't need the battery, so shouldn't be included in the return on investment if I understand your post correctly. I doubt it makes a big difference I have run almost the exact same calculation today but am less convinced that a 10+ year timeframe to pay off the initial battery cost is so reasonable, especially as the batteries are not guaranteed and may well have issues and/or degrade significantly during that time. It's fun to optimise but until I have a bit more confidence in the battery (and associated hardware) life being well in excess of the time to recoup initial outlay I think I'll hold off. Hopefully it becomes cheaper and better in the near future.

Actually on a day with some cloud and If I'm running the washing machine if the sun goes behind a cloud the Battery will boost what is coming from solar rather than draw from the grid as it would without the battery, then when the sun reappears it recharges the battery

Down a coal mine? Think bigger. Reliable, consistent, safe, repeatable rocket launches and we just chuck the stuff into the sun. Ultimate garbage bin. Of course we'd need to get Vlad and Pooh Bear on board with that but...

I heard an "expert" on radio the other day and they were saying it's more difficult than we can imaging to drop something into the sun a small miscalculation and the projectile slingshots round the sun and potentially comes back at huge speed

It would have to be a pretty big miscalculation.

It would have to be a pretty big miscalculation. I suspect the calculations to do it deliberately would be a lot harder. Still worst case, we catch it in a big net and have another go.

Giggling to myself
There's a petition on Change.org calling for all households in the UK to be given enough electricity to provide heating, lighting and cooking for free This would be paid for by a tax on the profits of the utility companies.
the Average UK house uses 2900 kWh of electricity and 12000 kWh of gas
Now lets take Octopus as an example they have 2 million customers.
Wholesale Price Of Electricity abut £245 per MWh so each customer would cost just over £700 at Wholesale prices ie with no profit to pay taxes on. so a total proposed tax of £1.4 billion
Octopus paid 8.9 Million Tax in 2021 turnover was £1.9 billion cost of sales £1.8 billion
where do these muppets get the idea companies like Octopus can afford to pay 3/4 of income in Tax
