‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off
(www.theguardian.com)
This is a most excellent place for technology news and articles.
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.
8-10 years is a fully fledged pv system. The small balcony panels pay themselves after about 5 years, longer if you add a battery.
