A feed-in tariff is a payment that is made to you by your electricity retailer for the excess energy that your grid connect solar power system generates and feeds back into the grid. The amount you will be paid will depend on the rate that is set by your electricity retailer, which can vary between states and territories in Australia. In general, you can expect to receive around 6-10c per kilowatt hour (kWh) of excess energy that you feed back into the grid.

It is best to have a professional assess whether your building is suitable for a solar power system. Factors to consider include the age and condition of your roof, the orientation and angle of your roof, and the amount of shading on your roof.

Solar power systems typically have a lifespan of around 25-30 years. However, this can vary depending on the quality of the system and how well it is maintained.

Birds can damage solar panels if they build nests on them or if they defecate on the panels. The acid in bird droppings can actually etch the surface of solar panels and reduce their efficiency. If you live in an area where birds are a problem, you can install a wire mesh over your solar panels to keep them away.

There is no direct answer to this question, however, some studies have shown that homes fitted with solar panels sell faster and for a higher price than homes without solar panels. The most probable reasoning is that solar panels are viewed as a valuable amenity.
