Föderation EN Fr 25.04.2025 12:28:40 @knud @bovine3dom @ives @fj A friend who’s a specialist in this told me that he thinks you could get the benefits of home rooftop solar more efficiently by having a central solar array in each neighbourhood, reducing installation and maintenance costs. |

Föderation EN Fr 25.04.2025 12:36:08 @benjamingeer @bovine3dom @ives @fj I partially agree, this again is a question of available space. What I think would be more important is a neighbourhood _storage_ facility. This leaves the city-wide grid untouched, allows local production and consumption. The trend here in Germany is for everyone to put a battery in their basement (us as well) but that's solely a result of the laws, not of efficiency. Production-wise, private households could just produce all they need. |

Föderation EN Fr 25.04.2025 13:10:56 @knud i think you have the same dimension mismatch because lots of people live in flats in a 3D fashion, but roofs are 2D not to mention the nightmare of arranging access to hundreds of roofs compared to a single farm i must admit i haven't seen any hard numbers on this, it just seemed obvious to me that installing and maintaining loads of solar in an empty field would be cheaper than doing a couple of panels across each of hundreds of houses. autoconsumption might change that |
