Residential and Commercial Solar Installation Process

Key Steps in Solar Installation

Solar installation typically involves:

• Site Assessment and Design: Assessing solar potential, roof condition, shading, and energy needs to optimize system design.

• Product Selection: Choosing durable and efficient solar panels, inverters, and mounting systems from recognized manufacturers.

• Installation: Certified installers secure and connect the solar arrays in compliance with Australian standards.

• Grid Connection and Commissioning: Connecting the system to the grid and conducting tests to ensure proper operation.

Costs and Financing

Residential solar installation costs vary depending on system size, components, and location, commonly ranging from AUD 4,000 for smaller systems to over AUD 15,000 for larger setups. Leading companies often offer financing options such as loans or solar leases to support broader accessibility.

Warranties and Guarantees

Companies like Solar Harbour and SolarHub emphasize workmanship guarantees and warranties, which often cover ten years or more, adding consumer confidence to solar investments.

Renewable Energy Solutions Beyond Solar Panels

In 2025, several solar companies also offer:

• Battery Storage Systems: These store solar energy for use during nights or outages, supported by programs like the Cheaper Home Batteries Program.

• Home Electrification and EV Charging: Integration of solar power with electric vehicle chargers and energy-efficient home appliances.

• Commercial EPC Services: Engineering, procurement, and construction services for large-scale solar projects are offered by firms similar to Autonomous Energy.

• Maintenance with Drone Technology: Companies such as Skykam Ltd use drones with thermal and high-resolution cameras to detect faults efficiently in solar farms.
