@mu oh no, these big names, easy-to-install batteries, are absolutely a bad investment (as far as money saving is concerned) Payback would probably take 20 years at the rate I mentioned, but this battery is unlikely to survive that long; in fact, in one year it has already lost half its capacity 😅 These branded batteries are not the way to financial savings, but they are easy to setup and they do provide a nice buffer for unpredictable energy loads that you don’t want the grid to take on @smallsolar

@GuillaumeRossolini @mu I think we have to move away from hoping that everything will pay for itself, part of this is to change the way we use energy and the way we source it. There is a rebellion in each of these steps, each time you use your panel you are taking back a little bit of agency. The 'green' revolution we all want isn't going to pay for itself but we've got to do something!

@mu in my case, being conservative that’s less than 400 kWh per year, and that’s less than 1/30th of my energy needs So all in all I know this is not very relevant, compared to heating (and cooking to a lesser extent), but we do what we can 🤷‍♀️ My view on this is, these systems at least allow us to avoid sudden, high, unpredictable loads from the grid, like for example washing machines and vacuuming. The grid can’t predict that the population will likely vacuum their place at xyz time every day and therefore there’s an increased energy need at that time every day. Of course, the conundrum is that they’ve been doing that regardless, and my changing habits now might be worse for them @smallsolar
