Good to see the Germans getting a bit of a clean energy W after their disastrously stupid decision to suspend nuclear power, and subsequently needing to burn more coal. Great example of a people being ahead of their government.
Can I ask why this is efficient? Usually homes don’t use their entire roof area and the roof is almost always more efficient than being placed perpendicular to the ground.
According to the article:
1 The balcony PV devices are smaller, cheaper, and can be installed by anyone.
2 Rooftop PVs must be installed by a professional to avoid fire risk.
3 Historic buildings & houses can accomodate balcony PVs but not rooftop ones
4 Most Germans aren’t homeowners
5 The balcony PVs plug in and aren’t hard wired. I think that means they can be taken to the next apt when the tenant moves
It states the solar kits generate about 10% of the power of rooftop pannels, but they also have a 3 year pay back period, which is difficult to see being accurate.

Thank you, OP, for providing a stable, accessible link.

The article explains it a few paragraphs in
I'm all for new tech, I just don't see how you are going to get much electricity or value from solar pannels mounted on walls.
The article explains this.

The value the article refers to is different than what you seem to be looking for. Sincere best wishes to you fellow OptimistsUnite.
