Meanwhile in Berlin, the incoming government decided to half the amount earmarked for building and maintaining bike lanes. Climate change is the last thing on the German government's mind, no matter what they claim.

You're forgetting that not everyone wants such a thing on their balcony and that you'll need to find someone to manufacture all of that (other countries want their solar still, too; it doesn't help us to deny Australia years of solar panel production only to put many on cloudy north-facing German balconies).

I don't know what the acceptance percentage as well as a realistic manufacturing rate is at such an order size (probably pretty fast), but it sounds like you're assuming the answers are "near 100%" and "a few years".

That's what I mean with let's figure it out and stick to execution. Production will probably not meet demand at first, but we need to get going. And we need to get going big.

- Let's make it mandatory to install fixed solar systems for new development areas and any newly build commercial buildings. The state will subsidize 90% of the cost for the initial setup for private households, for companies it's just a tax deductible expense.

- You want to retrofit your existing house with a fixed solar system? That's 90% subsizidation for you, too!

- You have a multi-party house (details needed) or a professional housing company? You'll have to retrofit your buildings in 5 years of time from now on.

- Let's retrofit all public buildings with solar systems. No excuses, execution asap.

- The state will encourage research and development of energy storage sytems by providing funds to universities etc.

We'll also need to have lots of laws changed and have our energy companies put in to place, but if the cost is low for the individual person, people will just make this happen.

Yeah, it will cost some money, but the money is there, it's just an allocation problem.
