  1. @owgf.org There are panels now that get sunlight from both sides. I don't know if that's what they have, but if you're trying to do something similar, that's what you should use.

      Yep. They are called bio-facial panels. And we also have Tandem Solar Cells too.

  2. @largess @owgf.org its not just about "green", it actually saves money. One of those pays for itself in 2 to 4 years with current panel prices. My small system (6x100W panels, shaded after 2 PM) generated 430 kWh this year so far, approx 50% was used and saved 100€ in electricity cost.

    There are flexible modules that cannot kill someone if they fall down, what about those?

    This whole thing took a long time to take off…
    Today there are 805871 registered Balkonkaftwerke with 500 MW
    Prior to 2024 there were 413788 registered Balkonkraftwerke with 240 MW
    Prior to 2023 there were 125227 registered Balkonkaftwerke with 65 MW
    Prior to 2022: 29482 units with 16MW

    My first Balkonkraftwerk is producing power since summer of 2020

    1. Great to have someone with a Balkonkraftwerk installation commenting. Anything else in your experience, of note?

      1. @owgf.org they do not need to be mounted on balconies ("Stecker-PV"). I know people who mount them as roof over stairs, just on the side of a building, on a flat roof, on a garden shed, on the side of a mountain… I encounter a lot of those systems on my daily commute.

        Maximum allowed power per power meter is 2kWp panel power and 800 W Inverter output (was 600 W last year). Batteries are possible, but no battery system (except DIY) makes financial sense for now.

        Live data of the own system totally changes usage of electricity. Without an own, small, system people just do not care at which time they use electricity as it costs the same all day. As soon as it is possible to save money they develop an awareness and move usage of some appliances. This behaviour change and awareness help the grid as well.

        Feel free to ask questions 🙂

        1. Thanks for sharing that too. They are excellent insights. I hope this is just the beginning. If you already had a camping battery like a BLUETTI Power Station then you would probably using that at home too?

          1. @owgf.org there's new portable devices now on the market, that act as a power station with Offgrid functionality, but also as a Ongrid #Balkonkraftwerk with battery
            See e.g.:– Mentech BP2200– Alpha ESS VitaPower – Jackery Navi 2000– Anker Solix 2 Pro– From 2025: APSystems EZHI hybrid micro inverter with broad 48V battery compatibility

          2. @ZamhoidnLA @owgf.org regarding camping batteries / "powerstations": If they are already there it makes sense to use them. The battery cells got a limited lifetime in years and charge cycles, so adding more charge cycles or matching the two leads to more stored energy = more money saved.
            But: the main challenge is to charge the battery only from excess solar power and to only use battery power if needed. This can be achieved in various ways, sometimes the manufacturer provides some ways to do this (e.g. solar input), sometimes a hack like connecting an inverter to an 12 V output via some current limiting boost converter and rolling your own control loop is needed. Maybe it makes sense to conenct all the loads to the AC output of the device, but this will lead to extension cords everywhere (or fiddeling with mains wiring).

          3. @stereo4x4 well, the systems we explicitly mentioned support (full) dynamic Ongrid fed-in, via Smart-Plugs (or a smart meter).
            When deciding to buy a power station of a certain size and capacity, consider taking one with Ongrid functionality.
            For battery systems already available, you can either use them Offgrid or attach a micro inverter to it. This won't result in a dynamic fed-in, but usually can cover the base load of the given household.

      Ours (amount admins and family) first one since 2017, already 😎

  3. @phneutral true, #Aiwanger was among one of the first to promote #Balkonkraftwerk in Germany, while at the same time ranting against "green ideology" and having strong ties to #Gazprom, #AfD and the #nuclear industry.
    Also #Saxonia (AfD stronghold) has a particularly high number of (officially registered) #Balkonkraftwerke per capita.
