‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off

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.
