the electrical grid should and eventually will be decentralized. It might not even use DLT whatsoever (it could tho - POWR token), but lets assume that as the price of solar goes down, its adoptability goes up. Residential areas and Commercially zoned areas with solar panels can sell excess electricity to each other or back to the grid (i.e. the utility company). Right now utility companies have centralized power and they sell for X amount per kilowatt hour. Eventually their power sources will be a decentralized grid of smart houses/businesses that sell excess back to the Utility company or to other homes and businesses directly. ---> this sort of thing is already happening, just on a small scale

https://www.sciencedaily.com/releases/2015/02/150204102637.htmSo what is someone will invent another super powerfull power source. Just like todays nuclear stations but safer, cleaner and more efficient. And everything becomes centralized again. Making a special comercial zones with solar pannels imho seems like a waste of space, putting such pannels somewhere in residential areas also doesn't seem efficient, especially if you need to provide electricity to the whole city. Centralization of the power supply is not a problem. I haven't seen anyone arguing about it tbh.
The problem of hacking that was described in the article imho is taken from nowhere. Centralized power sources are working for many years and they hardly suffer from hack attacks. Meanwhile blockchain is barely tested in this field and may cause much more problems then we expect.
I think you misunderstood what I meant regarding commercial zones, Existing commercial zones (supermarkets, shopping malls, warehouses) can all have solar panels without it being a waste of space, it would in fact be and efficient use of space.
Creating a new zone just for solar, i agree, in most cases is not an effective way of using space/deploying solar panels
