I am looking at eh new Tesla battery for home use, it may be a good option, but most likely it will be a few years before it is affordable. There are several companies in the island offering solar power tied to the grid as back up or night use.
We seem to think alike, I was considering the Tesla batteries also. Since a lot of people use little electricity during the day because the windows are open or they work, there is little savings if drawing from the street at night. I would only consider it if I don't have to draw from the grid. I think the batteries are affordable if they last a long time and depending on how many one needs. Tasks batteries are to run around 3,500 each but I have no idea how long they last.
