I think it will vary widely on location, and terrain.
I also guess that sticking them on the sides of tall buildings is a 'thing' too.

Totally, but you usually only do that if there are no good options for placement at all and you have to make do with what you have.
So that battery box i made last year from scratch that i complained about where i really didn't save anything of any amount by doing it myself. It did have the advantage i can remove batteries and such.
Amazon had lithium batteries on sale, picked up 4. Swapped out the 3 lead acid that were in there. its about 1/3 the weight + an extra battery.. its amazing how much lighter. Going to wire up the lead acid ones and stick them on a wire rack out in my 'server closet'. Add a plug to this box so it can charge/use the lead too, but still be portable, and be expandable if i wanted to add more batteries to the shelving. Could even add car batteries if i had to in a pinch if things really fell apart.
Still not saved any money, but its a bit more useful now as a 'portable controller' than being a huge concrete block with a handle.
It seems vertical ground mounting is a thing. Facing E/W (
panels on each side ) not a ~30 degree facing south. I had
actually thought about trying that, after watching the sun
really closely for a few days now.
That'll work as long as they are wired in parallel, or even better, on separate charge controllers.
I'm trying to learn as much as I can about using a battery bank to unify a bunch of different inputs and outputs as long as they are all the same voltage.
As previously mentioned I am trying to move all of my computer gear to 12 volts DC so I can keep it all running even through disruptions (even though my power is quite stable. It seems that a single battery bank plus multiple charge controllers would do the trick.
...which I should have already known, having grown up around boats.
some systems are 24 v, but same principle, wire them in parallel so you always get some current. I am running 4 in parallel since my stuff is 12v
in theory the higher voltage would experience less of a current drop than a lower voltage system
Lol. Trying to find the name of an old local tool store like Harbor Freight for a friend of mine, as far as where i got my mill and lathe ( but was better, and had larger stuff ).
No luck, but ran across a random 'review' of a battery brand " they suck because there are so many counterfeits that are unsafe". How the hell is it their fault?

I looked at a lot of web sites and watched a lot of videos. Everyone seems to agree that you can just sort of dogpile lots of chargers and loads on the same 12 volt battery system as long as they are wired in parallel. That's neat.
One site suggested that if you simply put jumpers down the parallel rows of terminals, the batteries "closest" to the chargers and loads will get more charge and more load, making the batteries wear unevenly. Then he suggested a very weird wiring arrangement with cables going all over the place. He must be stubborn because comments were turned off. It took me about two seconds to think that all he had to do was connect the batteries to bus bars with equal length cables.
Well, that is disappointing. ( continuing the solar thread )
Couple of years go i bought 2 more panels to store away for emergencies, instead of mounting them. What i got last time was out of stock, so got a different style. Same brand, but different shape, which should mean nothing if the same number of cells. ( more of a rectangle than a square )
Set them outside where i had the one i have been dragging around the yard testing. While i don't expect any of them to be 100% rated value, as nothing is 'perfect' they should at least pull what the other did in the same spot. But it was less than 1/2 the wattage. Even with both running, was just slightly less than the other on its own. getting 75 out of the single, 59 out of the pair. Grrrr. Tomorrow afternoon will test each one separate, see if its just one that is bad and causing an issue to the other. But i suspect its just crap.
I really think i should have bought that ZPM out on aliexpress when i had the chance a few years ago.
Ya, the way most people do if you have more than 4 batteries...
