I know that the NSW feed-in tariff will only be paid for electricity generated in excess of that used by each household, but HOW will that be calculated? Will it be by the minute, hourly, daily, monthly, weekly etc?
This is crucial as, depending on the method used, the actual amount of money each system earns for it's owner will be greatly affected by method of calculation. The shorter the time the better for the owners, The longer the time will mean less return for us!
