Rooftop solar is incredibly popular here in Australia. I think it’s something like 33% of houses have it. We also have a great climate for it.

I have solar on my house and am seeing around 50% self sufficiency overall. Of course with this much saturation, the rate you get paid for feeding back to the grid is quickly dropping to zero. So self use is the game now.

The problem is now shifting to home batteries and storage. Because peak power household use times are in the evening when the sun is not shining.
