Key takeawaysDetermining whether solar will suit your roof comes down to solar potential. Traditional asphalt and metal roofs are the best materials for solar projects.
Are all roofs suitable for installing solar panels?
Generally speaking, almost all roofs are suitable for installing solar panels. That being said there are roof types that are better for optimising sun exposure, as well as being easier and cheaper to install solar panels on.
Some roofs are better suited for solar panels than others. Solar installations work best on metal roofs, especially those with standing seams, because they are strong and mounting systems can be attached without creating holes. Metal roofs also keep the heat inside and are energy-efficient, which makes them perfect for solar power.
Do I need to repair my roof before installing solar panels?
If your roof is in poor condition, repairs will be necessary before installing solar panels. The orientation of your roof affects how much sunlight it receives. The best orientation for solar panels is south-facing. East and west-facing roofs are also viable, but north-facing roofs are less suitable due to limited sunlight exposure.
If your roof isn't suitable for solar panels, don't despair. Ground-mounted solar panels are an excellent alternative if you have sufficient land. Wall-mounted solar panels are another option, particularly for homes with limited roof space. Consulting a professional can save you time and ensure you get the most out of your solar installation.
Having your solar panels placed at no angle or direction on a flat roof is not ideal. However, a flat roof gives you the opportunity to have tilt frames installed at the best angle and direction for your solar panels to get the maximum exposure to the sun. If you have a flat roof, ensure your solar installer adds tilt frames to your quote.
Can solar panels be installed on wood shake roofs?
Wood shake roofs are not suitable for solar panel installation as they are potential fire hazards and present safety issues. Roofing materials made from slate tiles and clay aren't suitable for solar panel installation due to their fragility, making it challenging for contractors to mount them. Some jurisdictions won't permit solar panel installation on wood shake roofs.
