Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
Wrong question. The right question is: is the solar panel able to be CO2 neutral (at least) or CO2 negative. We don’t get anything out of it if producing the solar panel costs more CO2 emissions than it saves by producing electricity.
Before you ask: I don’t know the answer. I was looking into this thread in hope to find it.
I hung a solar panel vertically on my fence one time. It was facing west rather than south, but I was only getting about 3-4 watts on my 100 watt panel under the best conditions.
By putting the solar panel at a 90 degree angle though it is much less efficient than e.g. a 45 degree angle.
Less efficient than not having them?

Depends, is an imaginary angle comparable to a 45 degree angle?
