yeah it's nice but if you rent, most owners forbid putting it on the railing (e.g. because it could fall down).

- nine_k 2y agoThe landlords may install such panels, and pocket the savings / profit from generation. BTW from my back-of-envelope calculations, the panels are the cheapest part, the inverter / charger costs more, and batteries to sustain several hours of load, even more.
- 7373737373 2y agoI still don't understand why landlords (especially big corporations with tens or even hundreds of thousands of apartment buildings, garages and parking spaces) don't make use of the huge roof area they have.
- nine_k 2y agoSome of them do, even here in NYC. A quick look on Google maps e.g. over roofs of Brooklyn, where buildings are much lower and roofs are wide, shows a large amount of solar panels on more flat buildings, like stores, warehouses, or hospitals. Sometimes I notice installations on roofs of 3-5-story buildings just while walking around. But many apartment buildings (here) are too tall for the roof to capture enough energy, and mounting solar panels on walls is both not very efficient (because of the light's incident angle) and much harder.
- positr0n 2y agoHow does the height affect the energy captured? Or are you meaning the steepness of the roof?
- nine_k 2y agoIn a tall building, you have more floors that house energy consumers, for the same amount of the roof space. This means that the energy captured offsets a smaller share of the electricity consumed by the building, and the complexity may not be worth it. Usually roofs of tall buildings are already crowded with radiators of HVAC systems.
- junga 2y agoLaws regarding this just changed (couple of days ago). Landlords can't just forbid this anymore. See https://www.heise.de/en/news/Balcony-power-plants-Federal-Council-waves-through-relief-9955858.html https://www.heise.de/en/news/Balcony-power-plants-Federal-Co...
