‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off
‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off
Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
This is really nice! This is the future!
I'd love to know how much they produce, especially during the winter/monthly.
Wait that’s a thing?
Holy shit that a thing!? That’s awesome!!
“Plug-in solar is part of the whole array of options,”
I don't understand how this works? For our system we need an inverter that cost about $3000.- (half if it doesn't have to handle a battery), and it needs to be installed by an authorized electrician.
For a small system as the one shown, the price of panels are peanuts, the 2 panels shown should cost less than $150 combined. While the cost of inverter and getting it connected is way way higher. There's a lot more to this than not being on the roof!?! But which isn't disclosed.The article says nothing about how the power from those panels is made usable.
If you pay 3000€ for an inverter then that's probably included installing and whatnot. You can get a cheap 50€ 4kW inverter on aliexpress, or an expensive 500€ 10kW one.
The "balcony" bit isn't the defining characteristic, it shouldn't be taken literally. Some people do have their "balcony solar power" on their roofs.
What defines it is limitation to 800 W and inverters that come with a normal Euro Type F ("Schuko") plug and no legal requirement for professional installation. A layman can literally plug it in to an existing wall socket. Given that they are capped at 800 Watts, the inverters are also the simplest type and dirt cheap (although often they are literally just software-capped and identical to higher power ones, make of that what you will). Complete systems (2 panels, cabling, inverter) cost between 299€ and 800€ depending on quality. You genuinely only have to buy a fixture that suits your needs and a mate to help you install it.
Proper several-Kilowatt-systems are very expensive in Germany too.
Thanks really good info. 👍😀

That's amazing, I had no idea that is possible??? Is that special for Germany? (sorry for keeping on with new questions). 😋 I've never heard of that option here in Denmark.
cost between 299€ and 800€
No wonder it's a popular option, our system is of course bigger with 11.2 kWh and 7.5 kWh battery. but it was $17000 1½ year ago. Prices have dropped to $12500 for a similar system, but still such an 800W system is dirt cheap by comparison.
Have a look here: https://en.m.wikipedia.org/wiki/Balcony_solar_power
OK thanks, so they are indeed complete systems including inverter, so it can be connected to the grid.
I suppose they've made some cheap low power inverters then, but the power still needs to have stable voltage an frequency and synchronization. So I wonder how cheap it's possible to make?
I also suppose it still needs an authorized electrician to connect it? Unless Germany has some fancy system that is prepared for "plug in" connection of a local power source.
I wonder if a whole building could use one or two inverters?
I feel that'll make the cost reasonable
For apartment buildings I don't think that's possible, since electricity is a per household connection with separate meter.
There are two main inverter approaches. One big inverter that takes the DC from a bunch of panels and converts it into AC and micro inverters where each panel gets it's own small one placed directly under the panel.
The micro inverters cost around $150 each. So you need around 10 panels before the single inverter becomes a good choice.
Installers love the micro because the install is easier. However as a owner with say 30 panels you now have 30 points of possible failure instead of the 1.
For first few seconds, I deadass though they are talking about Germans with a height of 1,5 meters.
Only Germans this high have balcony solar
Makes sense, taller Germans throw too much of a shadow to make the solar worth it.
That was me.
So why won't taller Germans get solar? I don't even see the connection to height... Oh, maybe they hit their heads on the panels? No, that doesn't seem likely... I don't get it.
In b4 nimbys complain it's an eyesore despite most people never looking up
Would be nice if grid tied inverters weren’t such a regulatory PITA. Micro-deployment solar, and more importantly distributed energy storage, makes so much sense and could solve a lot of grid-related problems.
I can tell you I have a portable solar battery for emergencies and if I need to use it the right place for the panel is in my balcony, so this makes a ton of sense. In an apartment building roof space is relatively small per unit, but at least where I am every unit has a balcony. In my case even a rear-facing balcony that doesn't face the street but still gets sun for anywhere between 4-10 hours a day. If/when I am in a position to explore a solar installation this would be a good thing to look into.
Germans also have 7 times the power bill
I blame Bavaria. If Germany had multiple price zones like other European countries instead of one giant one prices would plummet here in the north, while they'd explode in Bavaria. The state that does not want wind power, does want nuclear power, but already knows ahead of time that its geology (with lots of mountains and granite) is unsuitable for nuclear waste storage. Meanwhile, north German wind power and Scandinavian hydro dams complement each other perfectly. The Bavarians could do the same with the Austrians, they just don't. They want to eat cake and have it, too.
Those small balcony systems pay for them here in Germany at ~35 Cents/kWh in a few months. Even if your power bill is 7x cheaper, they will pay for themselves easily.
nb4 someone laughs at us Germans for pulling out of nuclear power: No, nuclear is not cheap. It's literally the most expensive way to generate electricity. Solar is cheap and better for the environment.
French electricity enters the chat.
Nuclear is cheaper than your average electricity cost.
I know because I'm Swedish and you use us as your cheap electricity.
No, nuclear is not cheap. It’s literally the most expensive way to generate electricity
Source?
Beats coal anytime. Or Russian gas.
Nuclear is reliable, predictable and stable 24/7 source. Solar not so much and possibly not that great for the environment if we don't figure out what to do with used solar panels. Also their production is not exactly clean. Whereas nuclear requires a wasted fuel storage somewhere and the fuel will eventually run out of radiation in some hundreds of thousands years.

Oh no! Quick! To the incinerator!
I am not sure 1.5m Germans all deciding on a single course of action is something to be happy about.
You have Trump now. It'd be our turn to make jokes, if we had any humour.
Nah, making fun of germans is always ok, especially now that at least 1 in 5 voters are voting for literal Nazis again in Germany.
We have passed the torch of a fascist dystopia to another country.
A mere drop in the bucket when 77m have decided on a much worse course of action in another country.
Oh, German=Nazi reference, how original.
Nearly 100 years on time to move on and focus on the ones that carried it on I think
