The answer to this question is well over $6000 off your rising electricity costs. Over the last few years Australians have seen repeated electricity rises, of between 15% to 18%! Now let us assume for the purpose of this exercise, your electricity rises at the same rate, over the next five years. A 2kW Solar PV system installed in Sydney, will generate when averaged, around 7.8 kW of free electricity per day. In July 2013 a very common price for electricity per unit, will be around 30 cents. A 2kW Solar PV system installed at this time, can be forecast to make maximum savings of just over $6000 over a five year period.  Our maths is based on close to 100% of the generated electricity, being used in real-time. In the first year, savings are $854. In the second year, $1008 and so on. Finally at the end of five years, your 2 kW Solar PV system will have offset up to $6154 of electricity!   This is $6000 plus of electricity costs, you are going to be paying over the next five years, should you do nothing! Remember this only is the cost electricity used during the sunny hours of the day. Not your total electricity bill, as this will be far greater!
