This blew my mind as an Australian, I had a 9.9kw system installed for about $3200AUD from memory, there was a rebate but I’m unsure how much.
I get a minimum like 18kw a day on really cloudy days and up to high 50s on a good summer day. No batteries but it’s drastically reduced my power bill.
I used to hear ‘better than a poke in the eye with a blunt stick’
Whatever the fuck that means
