It's addictive though. Living in the center of the city (The Hague, NL), with a home battery, I'm now 100% self-sufficient electrically for 10 months of the year.

On your map, let's say the source is valid, UK has $0.4 I'm from CZ, on your map we have $0.35.
UK has more than double median salary, DOUBLE. Which means that in some cities it will be actually more like 2x or 3x smaller. But price of electricity is more or less same in the whole country here.
Don't tell me something about expensive electricity and saving money. Because on top of that, let's check affordable housing stats

Yep, one of the worst in EU, yaay.
And the great thing is: this is only if the panel was produced with fossil fuels. So due to increase in green energy everywere, this number goes down too and a PV can easily be used for 15 years and after. After that it might just be more economicly to reinvest in a new set of PV panels while the old ones can be sold and used somewere else.
This is with today's efficiencies. They are of course improving.
- Did you need/use an electrician to set this up? - How much KWh capacity do your batteries have? - What about fire safety? Did you install outside, or inside? - I assume dec/jan are the months you're not fully self-sufficient, are you allowed to charge from grid to do arbitrage over time, or is that another can of worms?
I wonder for how many people it will work in practice?
Putting panels on the roof should be much more efficient…
I bought a 1600Wc + 1.9KWh kit (Ecoflow Stream) for +/- 1300€ last summer. It took us about 2h to install (we had to setup a new plug outside), and I already saved 200€+ since July. I am expecting to save about 350€ per year.
Also, as u/jstch said, it's extremely fun to setup and generate your own power!
South facing?
Buying supports for PV is actually less economical than buying additional PV panels.

You have special electric meter and you are distributing solar power into the grid outside of your household?
Or you don't distribute electricity into the grid?
With a e-meter, you will get compensated when you're generating a surplus (+/- €0.04/kWh last time I checked).
However, thanks to the battery, I'm self-consuming almost all that electricity, saving around €0.30/kWh.
Expect 800kWh of annual production per 1kW of panels.
(this is country dependent)
If they think they can get an ounce more sunshine, they'll hang it over the edge, badly
Because here, small country in EU, this is not allowed since it would mean ridiculous investment into electric infrastructure.
It's heavily regulated and you need special electric meter, license, etc. and still price of electricity is negative in certain times during the day, because everyone who could, got their solar power plant from EU subsidies.

If you want solar panels without having to get an electrician, you'd need to connect them to a battery that's not connected to the mains.
The post is about permission to plug solar panels into your main electricity.
Eg.: Small EU country, definitely not allowed and under huge fines. Without proper equipment, solar power plant license etc. etc.
You speak as though that were a bad thing. I'd rather not have people accidentally burning their houses down.
Once it's approved for an area, you go to your local shop, buy an approved PV system, and plug it in. No fuss, no worries, and your insurer must cover it.
Does it need its own earth? Will it switch off if it detects a residual current? Can it handle spikes in load?
Its even reducing your load on your main line beause the energy directly flows into the next consumer.
German socket has earth, thats fine. It has protection mechanism and shuts down if it can't sync to the powergrid. The panels only produce (in peak!) 400-800 watts. Thats not an issue.

Inspection revealed it had two 6 Volt 10 Watt panels in parallel and then 12V to 5V USB-converter.
When panels were reconnected in series it was quite OK.
Little worried about Lidl-quality also on larger scale.
It appears your could legally install one of these panels on the 15th of this month, but there presumably won't be any certified to comply with the regs on sale yet.

Given that these store-bought panels are being plugged into house AC, it follows that they have built-in inverters. Many grid-tied inverters are “grid follow”, meaning that they adjust themselves to grid frequency/phase. So, just speculating here… maybe the inverter senses when the mains go down and turns itself off? I would love to know from an EE what is actually happening wrt safety.
Same legislation as the non-plug&play inverters.

works well and is probably now refinanced.
