|I would have thought that it would be the electricity retailer who would install a meter. I would expect that the meter would measure both energy in and energy out and the retailer reads both each month (or so) and bills you for the net amount (or provides a credit?)
Thanks for that but AFAIK, having spoken to the sparky, he will be installing the meter. As to who supplies the meter to him (Wholesaler store or power company) I couldn't tell you.
The only way to measure accurately energy in and energy out is to have two meters/"meter-wheels" because what you pay for power and what you will be paid
for power (fed into the grid) will be completely different. Although I guess I see what you mean, the power company might be able to calculate the KwH fed back, and re-calculate the amount to be paid based on the current tariff.
are working towards FITs in NZ though.
I'm not an electrician so I was after anyone who knew about these meters etc or might I be better off holding off until we start to generate power...
