Solar panels in Australia have become an increasingly popular choice for home and business owners seeking to reduce their energy bills and contribute to a more sustainable future. However, not all roofs are created equal, and the type of solar panel you choose will depend on the characteristics of your roof.
Understanding your roof type: A crucial step
Assessing your roof’s characteristics is crucial before considering specific solar panel options. Factors such as orientation, pitch, and material can significantly impact the suitability of different solar panel types.
- Roof orientation: The direction your roof faces (e.g., north, south, east, west) significantly impacts solar panel efficiency. North-facing roofs generally receive the most sunlight, but other orientations can still be viable with proper system design.
- Roof pitch: The angle of your roof affects how much sunlight it absorbs. Steeper roofs often capture more solar energy, but flat roofs can also be suitable with the right solar panels and installation techniques.
- Roof material: The type of material your roof is made of (e.g., metal, tile, concrete) can influence the installation process and potential compatibility with certain solar panel mounting systems.
Upgrade your solar system without sending your old solar panels to landfill
If you decide to upgrade your solar system, Second Life Solar will pay to remove your old panels. We are pleased to offer current solar consumers an alternative thanks to our partnerships with the CSIRO, the NSW Environment Protection Authority, and Energy Matters.

Solar panels for different roof types
1. Metal roofs
Metal roofs are generally considered ideal for solar panel installations due to their durability, strength, and compatibility with various mounting systems. Their smooth surface provides a stable base for panels, ensuring optimal performance.
- Benefits: Metal roofs are generally durable and long-lasting and provide a solid base for solar panel installation.
- Suitable panels: Most solar panels are compatible with metal roofs, but consider the specific type of metal (e.g., corrugated, standing seam) and any coatings or finishes that might affect installation.
- Mounting options: Racking systems designed for metal roofs are typically easy to install and provide secure attachment.
2. Tile roofs
Tile roofs are also suitable for solar panels but may require additional considerations. The weight of the panels and mounting system should be carefully assessed to ensure the roof can support the load. Installing a sturdy framework or using specialised tile hooks can help secure the panels to the roof.
- Benefits: Tile roofs are popular in Australia for their aesthetic appeal and durability.
- Suitable panels: Solar panels can be installed on tile roofs, but special care must be taken to avoid damaging the tiles during installation.
- Mounting options: Racking systems that penetrate the tiles and secure the underlying structure are often used for tile roofs.
3. Concrete roofs
- Benefits: Concrete roofs are durable and can withstand harsh weather conditions.
- Suitable panels: Solar panels can be installed on concrete roofs, but the installation process may require additional preparation to ensure structural integrity.
- Mounting options: Common options include rack systems that attach to the concrete surface using penetrations or adhesives.
4. Slate roofs
Due to their fragility, slate roofs are generally not recommended for solar panel installations. The weight of the panels and mounting system can potentially damage the slate tiles. If you have a slate roof, exploring alternative options like solar water heaters or ground-mounted systems may be more suitable.
5. Corrugated iron roofs
Corrugated iron roofs can be a good option for solar panels, but they may require additional reinforcement to ensure the panels are securely attached. The uneven surface of corrugated iron roofs may require specialised mounting brackets or rails to provide a stable base for the panels.
6. Flat roofs
Flat roofs present unique challenges for solar panel installations. While they offer a large surface area, they may require additional structural support to accommodate the weight of the panels and mounting system. Ballasted systems, which use weights to secure the panels to the roof, are often used on flat roofs.
Best solar panels for homes
- Polycrystalline solar panels: These panels are made from multiple silicon crystals, offering a good balance of efficiency and affordability. They are suitable for various roof types and popular for residential installations.
- Monocrystalline solar panels: These panels are made from a single silicon crystal, providing the highest efficiency among traditional solar panels. They are ideal for maximising energy production, especially on roofs with limited space.
- Thin-film solar panels: These panels are made from a thin layer of semiconductor material, offering flexibility and lightweight design. They are suitable for various roof types, including those with limited structural capacity.

Solar panel installation tips
- Consult a professional: Hiring a qualified solar installer is essential for ensuring proper design, installation, and compliance with local regulations.
- Consider energy consumption: Assess your household’s energy usage to determine the appropriate system size and maximise your investment.
- Explore government incentives: Research available government incentives and rebates that can help offset the cost of your solar panel system.
- Maintain your system: Regular solar cleaning and maintenance will help ensure optimal performance and longevity of your solar panels.
Environmental benefits of solar panels
- Reduced carbon footprint: Solar panels generate clean energy, reducing your reliance on fossil fuels and minimising greenhouse gas emissions.
- Energy independence: Generating your electricity reduces your dependence on the grid and contributes to energy security.
- Sustainable energy source: Solar energy is a renewable resource that can be harnessed for many years, providing a sustainable solution for your energy needs.
Choosing the best solar panels for your home: Factors to consider
- Budget: Determine your budget for solar panel installation, including the cost of panels, inverter, and installation labour.
- Energy consumption: Estimate your household’s energy usage to determine the appropriate system size.
- Plans: When making decisions about solar panels, consider your long-term plans for your home, such as selling or expanding.
- Government incentives: Research available government incentives and rebates that can offset the cost of solar panel installation.
