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?
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.
Most people don't care about being CO2 neutral. The real question is what is the ROI? Will the panel save that person money. If it takes 50 years to pay for itself, I'd say that's bad. 10 years is more standard. 5 years I say it's a no brainer. Though I suppose you can also argue value for utility, if that is giving her the ability to power something off grid that would be worth something.
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.
Depends, is an imaginary angle comparable to a 45 degree angle?
I'm sure this is a good thing, but considering the vast majority of Germans haven't figured out screens on windows I'm not sure the appeal to authority in the title has the desired effect.
What screens are you talking about?
We have fly screens in our windows. Windows which can be tilted btw.
You also have the best shutters ever.
Like fly screens?
Becausr in that case I don't get it.
Maybe he/she refers to the operating system from Microsoft?
But what screens does he/she mean? Lock screen? Desktop? screensaver??
Very weird.
There is something in it - they are making solar panels with chemicals that makes energy trans
It's going to be hard to justify production costs, but in places that subsidize it: it makes perfect sense to scale up solar wherever possible.
Hard to justify costs? The article quotes 6 years of amortization. I know numbers around 8-10 years in Germany.
Show me any consumer investment, that gives such a good ROI.
The actual problem are electricity prices rising higher and that shortens to time to reach the equilibrium between the investetment
That's 4' 11" - I had no idea Germans were so short.
I wonder why only those people have balcony solar. Why aren’t other Germans interested?
First the trans people come for my energy, then they come for my trains? When will the madness end? Won’t someone think of the children!
