Wouldn't it make much more sense to deliver them with a battery? How would you connect a battery to such system?
Batteries are still relatively expensive, large and heavy; panels are extremely cheap.
Solar panels at Lidl? Plug-in versions set to appear in shops

#72I tried to set up Bluetti solar panel on my balcony in a similar way, but the efficiency was abysmal because of the angle to the sun. I wonder for how many people it will work in practice? Putting panels on the roof should be much more efficient…
Please tell your latitude or location.

These inverters have to switch off if they cannot detect a grid signal, or if the grid frequency/voltage goes out of the safe range. Same legislation as the non-plug&play inverters.
Does this mean if you have a main grid power outage the solar panel cannot provide your house with power either?
Mine (Ecoflow Stream Ultra) has two 1200W regular sockets I can use while the grid down.

Which energy bill? Monthly or yearly?
I pay 100 Euros per month energy bill and save 10% of it so 10 Euros per month or 120 Euros per year.
are you running bitcoin farm or cook and heat with electricity with 100 eur monthly bill? my yearly consumption for whole household of 4 people is around 1.2MWh (gas cooking, and external grid central heating), which makes like <400EUR per year in Czechia (infamous for high electricity prices across Europe) and already now most of my fees are not really my consumption, but distribution and other stuff, it's even worse with my gas cooking with only 0.5MWh per year, where I paid almost only fixed fees and not the actual consumption, but tried cooking on induction and hated it

#75Why do Europeans need permission from their governors to buy solar panels? I bet you also need to pay taxes on the energy you generate even though you alleviate the infrastructure need.
You need permission to connect it to the grid.
what if you don't want to connect it to grid and use it in islanding mode? seems like it shouldn't be anyone's business

Nope just a normal server running 24/7, a condens dryer, a gaming rig and working from home (so display, lights and kvm switch running 8/5).
240kWh per month, 35cent per kWh and a base price of 10 Euros.

#77We legalized these in Belgium last year. 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!
Did you need to get it certified? I think the limit for DIY balcony panels here in Belgium was about 800W.
It is 800W, but the battery allows it to buffer the excess and never output more than the legal limit.

The average consumption figures used by the UK regulator https://www.ofgem.gov.uk/average-gas-and-electricity-use-exp... are 7.5MWh gas and 1.8MWh for a "small" household, so I guess you're really frugal and/or well insulated?

It’s a new account that has posted only pro nuclear and anti solar/wind stuff since its inception.
You are both right and wrong at the same time. Long time ago when Siemens in Germany was still building nuclear power plants, I was working in the nuclear power plant engineering department. After the year 2022 when the Russia invaded Ukraine, the gas shortages and the following costs hikes renewed my interest energy sector. Why didn't German reverse it's anti-nuclear stance, even with war in Europe? Was is the gener…
I dislike ‘energy religion’. Nuclear is necessary for Europe. We simply can’t heat our homes and power our industry with renewables in winter. At the same time wind and pv can be built up faster and is simply cheap. Hydro where topography and local bio conditions allow it. We need all those technologies, so we can move away from fossil (climate, resilience and depletion).
