Before that I believe they had several wind turbines and a very small solar setup due to cost. One told me they have had their current batteries 14 years and the other thought it was over 16. Good numbers either way .  They said their previous set had lasted them about 20 years. The bloke said he keeps a good eye on them but doesen't actually do much to them. Said he tops up the watering system about every 3 months and that's it. I was talking to the scrappy yesterday when I got some used panels. He said the owner of the company that does the installs was telling him they are starting to see the tesla power wall batteries starting to puff up and having to replace them. I haven't read of this anywhere but then again I think Tesla batteries are pretty much a con so I don't pay much attention to anything to do with them. It would be interesting to find out how much the scrappy are paying for large batteries and what that effectively reduces the cost of a replacement pack. From what I got for car batteries a while back and what I have seen the forklift packs for, I'm thinking there is a pretty decent offset cost there.
