Its not “wasted” financially. I dont know the rates but if 1 unit costs 50c from the grid during the day they will only pay me 10c to feed into the grid, at peak times (evenings) they want $1 from the grid and I cant contribute. If I preheat/cool my house with 5 units of energy I would have only gotten $.50 for and halve my evening usage on maintaining it from say 10 to 5 im up by $4.50
The numbers are bullshit, but you get the idea.
Also down the track a little my wife and I are looking at making one of our cars a phev so we wanted to be able to charge it at home off solar.
