A solar installer assesses your home, designs a suitable system, supplies and installs the panels, inverter and other equipment, then arranges required electrical checks and grid connection paperwork. In Australia, installation work should be completed by appropriately licensed electricians, and it is sensible to check whether the business and proposed products meet relevant accreditation and Australian Standards requirements. Compare detailed written quotes covering system size, equipment, warranties, workmanship and expected timeframes. You can also check installer credentials and seek advice from your state electrical regulator before signing.
