I was also curious about the economical view of as well. These prismatic batteries promise like -cycles.
But how many cycles can salvaged from batteries can offer ?

I checked some new has 500 cycle life, can not imagine salvaged cells cycle life. If so why everybody use ?
It should be 4 times cheaper then prismatic new cells. Right ? Can anybody give some figures in order me to understand ?

(lithium-ion) can definitely last longer than 500days in a solar DIY system... but I agree its a question of how long that is interesting to me.
Here's a thread by @Generic -

There's also the famous Battery University page -

One thing about (s) is that they are 'many small units' (as apposed to a prismatics bank that would likely be fewer/larger units) and it might be that as my battery bank ages it will die in groups of cells here and there rather than 1,000(s) of cells all at once - so I may have a chance to extend the life by ongoing cell maintenance... which is why I designed my packs to be serviceable.

My oldest 14s120p battery is now 2yrs old with 603 cycles at average DOD of 44%and going strong. ButI need 7,000 cycles to break even, so it will be a while yet before I have serious data....One thing about (s) is that they are 'many small units' (as apposed to a prismatics bank that would likely be fewer/larger units) and it might be that as my battery bank ages it will die in groups of cells here and there rather than 1,000(s) of cells all at once - so I may have a chance to extend the life by ongoing cell maintenance... which is why I designed my packs to be serviceable.
