‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off
-
Isn't wind energy better on balconies?
-
8-10 years is a fully fledged pv system. The small balcony panels pay themselves after about 5 years, longer if you add a battery.

Personally, a remnant of that. Being able to use standard lead acid batteries is a perk, but primarily I find that that voltage range of < 20-50>vdc in terms of equipment is in those 12v increments too. With the powedelivery (PD) extended power range (epr) going up to 48v right now, and the fixed voltages in that spec being multiples of 12 again matching the industry it is now.
With adjustable voltage supplies (AVS) it might matter less (because it can increment in 100mv instead of a couple fixed voltages) but I haven't messed with that yet myself

Might be most efficient when power is in higedt demands, in the morning and evenings when everyone is using power at home.

Russia went trans even earlier than that.

Sadly really small wind turbines are really ineffective and not worth the investment until you have a really windy balcony. If you only have a few square meters solar is the only choice.
But I'd still love to have a small windmill in my garden.
-
You don't need a smart meter for this, just plug and play. If seen offers for complete sets from as low as 250€ in supermarkets, so almost everyone can get one and start saving some power.

My North-East facing balcony doesn't get enough sun light. But it's an interesting idea.
-
Doubt it. Wind around buildings tends to be shit.
There's a reason they build turbines on hilltops and out at sea.

The PC industry has been trying to get rid of those 3.3V and 5V rails for over a decade now, trying to get everyone on board with 12V only. The only hold-out in a modern PC should be SATA, at 5V, the mainboard already doesn't care and GPUs definitely don't. Also no -12V any more. Any year now, not that SATA will die that quickly but the mainboard knows how many SATA connectors it has and can provide sufficient 5V to power your disks.

I have to guess as anyone but I would say screen as in display/monitor. It must be hardware related.

Hell yeah. I do Thursdays and man people remember to come to me on Thursday.

The most have a 45 degree angle

Who is we? Lots of places do communal bath houses. Japan has an entire industry around it. Mass transit is also highly prevalent.
Yes there will always be some level of individual desire to do things or need in some cases but communal projects are useful and common I don't get the dismissal of that for energy creation something we long ago figured out was better to be done at scale and distributed after.
This is neoliberalism and treating it like it's the only way to exist. It's a failure of consideration or imagination. Either way your take is not right for that.
-
PRODUCTION COSTS.
It's assumed that the equivalent solar wouldn't be installed somewhere else, so you would need to produce more total to meet demand, meaning increased production costs with an upwards cost growth curve based on scale unless the materials, usually aluminum and slabs of silicon fresh out the oven or sometimes cadmium telluride, are already overabundant.
-
PD's default comms voltage is 5v at the moment too.
I'm for moving up the default voltage, but that is naive take for me. It just sounds right I have no idea the actual pros and cons on that low of level if that messes with components and what insulations to expect etc
-
ok so, even if we assume that you NEED to do this, which is an errant assumption on the basis of "you can just not have that problem through over provisioning" you could use that extra generated power for other things, selling to industry, energy storage, a community center whatever, there are literally endless things you could do with free power, most often you just dump it into heating since it's cheap, and storing it is fairly trivial in something like water.
At worst possible case scenario, your required grid imports are still going to be less than they currently are, which means less external grid maintenance, and less strain.
Granted it's not going to be used year round, unless of course, you over provision production and consume in the winter, and produce in the summer, where now you're getting effectively double the usage, if not more. You probably won't reach peak micro grid infrastructure, but the flexibility providing by something like solar is worth the consideration. A really good example of this is actually the texas power grid, although that is a pretty large power grid, i never said you should island micro generation, just that it's likely going to be beneficial.

in an apartment specifically? Why would you build your own house when you can build a large building and then live in segmented housing blocks within that building?
It's literally just breaking the entire idea of apartment block housing for the purposes of providing less usable, less functional solar power. If you want to do your own install on top of an existing install on the apartment, go ahead, nobody is going to stop you, but you would see more returns if you managed to install solar directly on the roof of the building in the first place. Economy of scale is going to be advantageous for you in literally any case, that's just the truth.
