I also recently got solar panels, they were calculated to provide more then my household consumes year-round, and should pay themselves back in 6-7 years based on 2021 energy prices and regulations. I anticipate having to get an electric car to use up all that energy :-) One thing the author missed is that in the Netherlands you can re-claim the VAT paid on the solar installation, saving 21% of costs. Probably not worth the effort for a very small installation, but for a bigger one it saves considerably.
