My neighbour is a big power user and has had a thousand dollar quarterly bill. He is currently installing 22 panels on his shed which is separately metered, ergo he will export it all @ 44c. but has absolutely no intention of rationalizing and reducing power use, just reducing his bill. Being a retiree, with up to four people at home every day, it is not a viable option for me we would export so little, hence my attitude.
