Though homeowners or business owners may attempt the job themselves, there are many reasons why a skilled and certified professional should be used for solar installation. The first consideration is quality work that is guaranteed. There are several companies that offer such service and back up their work with a guarantee.
There are essentially two kinds of solar panels that can be installed. Thermal panels are used to heat water whilst photovoltaic panels are used to generate electricity. A homeowner may be able to figure out how to do one but is not likely to be able to do both. You can also look for professional solar agencies in Australia.

Many companies that provide solar installation service know exactly which panels are right for the particular job or for the needs of the homeowner. They possess the knowledge to choose the right products for the job and the right way to attach them to the home. They must also possess some knowledge of construction as the panels will typically be placed on the roof, which requires cutting into the roof.
Also look for companies that hire and use certified installers to do the work. This is important as not everyone has enough knowledge and skill to place the panels in a variety of situations.
It is best to get an estimate before having any work done with solar panels. They can be quite costly and each home may have a different set of circumstances requiring different ways of configuring the system.
