There are numerous factors that affect your suitability for solar and the period it will take for your system to ‘pay for itself’. And as the cost of solar has fallen, so have government incentives. You should carefully consider whether solar power is going to be a worthwhile investment for you.
Most Australian electricity retailers offer feed-in tariffs, meaning that they pay you a small amount of money for any excess power you generate. However, the biggest financial benefit from installing solar power comes via ‘self-consumption’ – generating your own electricity instead of purchasing it from the grid at a higher rate. Accordingly, you should choose the size of your solar PV system based on the electricity consumption of your household or business.
