Brilliant news!

@raymaccarthy you do know the UK hugely subsidises solar, right?
And that new-builds will have solar by default. That's already law.
Rooftop solar for new builds to save people money
New homeowners stand to benefit from rooftop solar and cheaper bills, with the Future Homes Standard being published this Autumn.

I've got to ask, why are you such a doomer about this good news?
@Edent
Because it's mostly PR.
The Solar UPS was already possible without this is change and far better as It can make bigger savings & security.
The so-called "balcony" solar makes little difference. This is ONLY useful for people wanting to sell to grid that have maybe only one or two panels. You need a lot more, especially the darker half of the year to make a difference and then the extra cost of a certified electrician isn't significant.
Solar without the LiFePO4 batteries is stupid. -

No, that's not really correct.A battery is only good if you can plug stuff in to it. Which means you need to route your cables around - and it'd be impossible to plug an oven in to it.
Balcony solar goes:
* Panel out of window
* String to inverter
* Inverter to mains via plugThen *all* of your devices can use solar. Not just the ones within cable reach of your window.

No, that's nonsense.Talk to an electrician and look at power of panel.
A typical 400W panel only gives that for a few hours each day in clear sky in Jun/Jul. A cheap "balcony" system is 1/2 that.
Maybe 10W to 40W at noon in Dec/Jan on average.
Without a battery you can't use ANY of the 400W if the mains supply fails.
You don't plug anything into the battery!
You plug into the inverter or inverter/UPS. The Electricity companies don't pay well for the Solar to grid!
Oven is irrelevant -

I have rather a lot of experience with domestic solar.The point of balcony solar isn't to power your whole house. Nor is it to island your home in event of a power cut.
You're arguing against something that it explicitly isn't designed for.
It's to trickle feed energy into your home in order to reduce what you're drawing from the mains.
-
@Kerplunk you didn't read the Labour Party manifesto, did you?
They explicitly mention solar and other green policies.
Not sure how making it easier to get solar power is a trick. Do you want these policies now or only after another 3 years when Zack is PM?
-
@OneInterestingFact @Photo55 @Edent a 3kw immersion element doesn't have to be run at a continuous 3kw
But more importantly most homes have a small continuous power draw for things like fridges and devices on standby
A small solar panel will avoid having to pay for much of this power.
The smaller the solar setup the less "problem" there is with "excess" free power.
So a small cheap setup is likely to be highly utilised without storage.

Meanwhile, due to leaseholds and the seeming lack of reform on their rules, despite initial optimism, I still can't get solar anywhere near the roof of the flat I own. -

@matthewcroughan @raymaccarthy
Yes, that's the point of this proposal. You'll be able to hang them on your flat's balcony, or our a window. No need to drill into your roof. -

@matthewcroughan I strongly recommend writing to your MP to let them know you're in favour of it.

For anyone reading this who thinks "you can't buy plugin solar panels from Lidl!" here's a link to Lidl Germany where that is definitely a thing:

@gundersen no, we just let people die.
Of course they are considered. All inverters continually check for the presence of the grid's frequency. If the frequency is lost, it immediately de-energises.
@Edent haha, good to know you think of the people
I'm just sharing the objections of the Norwegian government. Is there a legal requirement for the balcony panels to have that kind of inverter? There doesn't seem to be an EU law, apparently. It would be good if we could just copy your laws, seeing as my government is mortally afraid of taking any decision on their own, but European champions in copying others laws

@OneInterestingFact @Edent Ideally, you use the battery to store your own solar production over the day to use in the evening. If your panels cannot fill the entire battery, you fill the rest with cheap energy from the grid (requires a variable energy tariff, of course). Such a setup should usually amortise within a few years. But 4.4kWp is already quite massive. That's not a plug-in panel for your balcony I suppose.
I'm still looking at TOU tariffs - I'm sure I could make bigger savings but it's a question of how quickly the initial cost would be repaid. For the sake of simplicity I currently assume all solar is exported though my spreadsheets do allow me to estimate self use savings.
Work in progress -
@OneInterestingFact @Photo55 @Edent I think the major hot water source in uk is still gas-fired boiler.
