In Queensland, your potential earnings for electricity fed into the grid are calculated using the

net metering system. Under this system only the electricity generated in excess of what your household

"consumes" is fed into the grid, and you receive a feed–in tariff per kWh for this electricity.

The Queensland Solar Bonus Feed-in Tariff scheme rate dropped from 0.44c per kilowatt-hour

(kWh) to 8c/kWh as of 12:00am 10 July 2012. In order to receive the 0.44c/kWh rate, customers

would have had to lodged their completed connection applications by this time.

The following are breakdowns of the calculations relating to the estimated return from your

solar system with two scenarios being presented.

The first is for households who qualified for the Queensland Solar Bonus Feed in Tariff of 0.44c

and the second is for households who missed out on the 10th July 2012 deadline and now qualify

for the 0.08c Feed in Tariff.

It should be noted that different electricity retailers offer increased Feed in Tariff rates by

supplementing either the 0.44c or 0.08c on offer from the State Government. Hi Tech Energy

Solutions advisers all potential solar investors to carry out their own research to ascertain which

electricity retailer in their region can offer them a package that best suits their individual requirements.

For both of the following scenarios we have used the "base rates" of 0.44c and 0.08c.

An estimated average supply tariff (what you pay for you electricity) of 0.22c per kWh has been used for both

                          scenarios.
