Damn, I've looked at it on Google and it's such an eyesore.

So are lawn flamingos - with the notable difference that Balkonkraftwerke actually do something useful.

With the notable difference that lawn flamingos are not necessary because of the terrible energy policies of the government, whilst balkonkartoffel are.

In other words you have lawn flamingos because you have bad taste not because the government impoverished you.

"Eyesore" is in your own opinion. What I've seen on balconies around here, anything covering them is a 50% chance of being an improvement — and unlike some acquaintances, I've not encountered balkon-FKK. And IMO they're a big improvement over, e.g. the AC units on the skyscraper walls of Manhatten.

I have balkonkraftwerk because they're a 60% return on investment, per year for 35 years, tax free and self-adjusting for inflation. By far the best (reliable) investment one can make.

That €350 is currently economically worth €7350 over their lifetime in reduced energy bills, tax free. The economics are so strong that it would be worth doing even if energy was 1/3rd the current price.
