may require larger systems or future battery storage options.
Understanding your energy profile helps ensure your solar investment matches your household's needs.
Assess Your Roof Suitability
Your roof plays a critical role in determining how efficiently your solar system performs.
Several factors influence solar production.
Roof Orientation
North-facing roofs generally receive the highest solar exposure in Brisbane.
However, east and west-facing roofs can also provide excellent results depending on your daily energy usage patterns.
A professional installer can recommend the most suitable panel layout.
Roof Pitch
The angle of your roof affects sunlight exposure throughout the year.
Correct panel placement helps maximise energy production.
Available Roof Space
A standard 6kW solar system typically requires sufficient roof area for approximately 13–16 solar panels, depending on panel wattage.
Modern high-efficiency panels require less space than older models.
Shade Analysis
Trees, neighbouring buildings, chimneys, or roof structures may cast shadows on solar panels.
Even partial shading can reduce overall system performance.
Professional site assessments identify shading issues before installation.
Choose High-Quality Solar Panels
Not all solar panels deliver the same performance.
Panel quality influences:
