Queensland Minimum 9.9 cents per kilowatt hour
South Australia Minimum 9.9 cents per kilowatt hour
There are several points that need to be considered to make sure solar is suitable for your residence. Your roof needs to free of rust and shade. Your roof simply needs enough space so that the solar panels will fit.
Most solar modules have a power output warranty of up to 25 years and a
product warranty up to 12 years.
While the generated power of the solar panel will slightly decrease through time it is expected to still be high performing at 80% capacity 25 years from purchase.
Solar arrangements connected to the grid need very small amounts of maintenance. It is recommended you have your panels cleaned once a year for bird droppings, dust, fallen debris etc.
If you make use of a high quality solar installer your roof will likely not be damaged. The panels have no parts that are moving but it is a recommendation that your solar arrangement be inspected every two years at least to make sure the system (the arrangement) is still intact.
You can still make use of your solar arrangement on cloudy days; however, the generated level will be lessened when there is a large amount of cloud coverage. The moment the sun comes out your system will be working as it regularly does. Tier one solar panel arrangements will still generate in a low-light irradiance environment.
