Solar Panel Installation Process Explained Step by Step

 Switching to solar energy is one of the smartest and most sustainable choices for Australian homeowners and businesses. With generous sunlight, government incentives, and rising electricity prices, there's never been a better time to install a solar power system.

If you're wondering how it all works, here's a simple breakdown of the solar panel installation process — step by step.

Step 1: Solar Consultation & Site Assessment

The first step begins with a solar consultation, where a solar expert will assess your:

  • Average electricity usage

  • Roof direction, pitch, and shade

  • Location and sunlight exposure

  • Budget and energy goals

In most cases, this is done remotely using aerial imaging and a recent electricity bill. If needed, an on-site inspection is arranged for more detailed analysis.

Step 2: System Design & Quotation

After the assessment, a tailored solar system design is created. This includes:

  • Choosing the right system size (e.g., 6.6kW, 10kW)

  • Determining the number of panels and their placement

  • Recommending a quality inverter and optional battery storage

You’ll receive a detailed quote showing the estimated output, return on investment, and potential energy savings.

Step 3: Government Rebates & Paperwork

Before installation, all necessary paperwork is handled for you, including:

  • Applying for STCs (Small-scale Technology Certificates)

  • Grid connection approval from your energy distributor

  • Any local council approvals (if needed)

This ensures you can access all available solar rebates in Western Australia and legally export solar energy to the grid.

Step 4: Professional Installation

Once everything is approved, your solar panel installation is scheduled. On installation day, certified solar installers will:

  • Install roof mounting systems

  • Fix panels securely to your roof

  • Connect the inverter and battery (if included)

  • Wire the system to your switchboard and meter

Most installations are completed within one day, depending on roof complexity and system size.

Step 5: System Testing & Grid Activation

Once installed, the system is tested to ensure it functions properly. The installer will also submit final documentation to your energy provider to:

  • Finalise grid connection

  • Activate any applicable feed-in tariffs

This process can take a few days. Once connected, you’ll start generating clean, renewable energy and see your power bills drop.

Step 6: Monitoring & Maintenance

Most modern systems come with a solar monitoring app, giving you real-time access to:

  • Energy production

  • Consumption trends

  • Battery status (if applicable)

  • System performance alerts

Your installer will show you how to use the app and explain basic maintenance tips to keep your system running smoothly for years.


The solar installation process is straightforward when handled by qualified professionals. From system design to final activation, each step is designed to maximise your solar investment and ensure a smooth transition to clean energy.

Whether you’re installing a system for your home or business, going solar in Perth is a smart move — both environmentally and financially.
