1. Roof Orientation and Angle

The first thing solar panel installers evaluate is the orientation and angle of your roof. In Australia, roofs facing north are ideal because they receive the most sunlight throughout the day. However, east- and west-facing roofs can also work effectively with slight adjustments in panel positioning.

The angle of your roof plays a vital role in optimizing solar energy production. Most roofs in Australia have an angle of 15° to 30°, which is suitable for solar panels. If your roof is flat, installers may use tilted mounting systems to position the panels at the optimal angle.

2. Roof Size and Space Availability

Installers measure the available roof space to determine how many solar panels can be installed. The more space you have, the larger the solar system you can accommodate, which translates to higher energy generation.

For example:

  • A typical 6.6kW system requires approximately 30-40 square metres of roof space.
  • Larger systems, such as 10kW, require proportionally more space.

If space is limited, installers may recommend high-efficiency panels that generate more energy per square metre.

3. Shading Analysis

Shading is one of the most critical factors that can impact the performance of a solar system. Installers conduct a shading analysis to identify any potential obstructions, such as:

  • Nearby trees
  • Chimneys
  • Antennas
  • Tall neighbouring buildings

Even partial shading on one panel can reduce the efficiency of the entire system. If shading is an issue, installers may recommend micro-inverters or power optimizers to minimize energy loss.

4. Roof Condition and Structural Integrity

The structural integrity of your roof is essential to support the weight of solar panels, which typically weigh about 20kg per square metre. Installers will inspect for:

  • Roof age: Older roofs may need repairs or replacement before installation.
  • Material type: Roofs made of materials like concrete tiles, metal, or asphalt shingles are easier to work with, while slate or clay tiles may require special care.
  • Load-bearing capacity: Installers ensure your roof can handle the weight of the panels and mounting system without compromising safety.

5. Roof Shape and Design

Complex roof designs with multiple angles, dormers, or skylights may require custom panel layouts. Installers will work around these features to ensure maximum energy production while maintaining aesthetic appeal.

6. Accessibility

Accessibility is another factor that installers consider. Easy-to-access roofs allow for quicker and more cost-effective installations. Steep or multi-storey roofs may require additional safety equipment and time, which can slightly increase installation costs.

7. Electrical Infrastructure

Before installation, installers check your property’s electrical infrastructure to ensure compatibility with the solar system. They’ll assess your:
