Factors That Influence Solar Panel Costs

System Size and Energy Requirements

Panel Brand and Quality

Installation Complexity
Roof structure, height, and accessibility can influence total cost. Homes with steep or shaded roofs may require additional mounting equipment.
Government Rebates and Incentives
South Australian homeowners benefit from Small-scale Technology Certificates (STCs) that can reduce installation costs by up to 30%. Feed-in tariffs also reward you for exporting surplus solar power back to the grid.
