Thanks for that info. The mate I referred to does live in an area where it is not possible to afford power. His last system - 1.5kw - lasted 18 years but basically only ran the lights and some other electricals - fridge and stove were gas.My sons and I build custom homes in a rural area. Son 3 and I come from and electrical background - Son 2 is a chippie/mechanic. We don't talk about son 1 - he is a geek and lives in Queensland 🤣 We don't compete for solar installations but do them on our own homes. I have done complete off grid systems and grid connected - with and without battery.
Unless you are off grid because you dont have power close enought it is not worth the effort. You would pay a lot of standard bills for the amount you will fork out over the life of the solar installation. What the solar installers don't tell you is that the average lifespan of the components is 25 years for panels, 8-12 years for batteries (provided they are looked after) and 8 years for the inverter. So plan on changing the inverter over twice, batteries at least once and then throw the system out and start again after 25 years. That adds up quickly.
I have replaced pelnty of Chunesium inverters after 4 years (right out of warranty). I expect you will find the same with some of the early lithium tech (batteries). You do get what you play in with your solar installation.
He prefers lead acid batteries rather than lithium and has installed them on his current system (24 volt). He now runs fridge, electricals and peripherals off that. Obviously he has to be frugal still.
I know it's probably pie in the sky for me with my electrical usage but I'm over the bullshit and ever-increasing costs of things just for corporate greed. That is exactly what has happened with electricity meters imo.
