Are there specific mounting systems required for solar panels on flat roofs?
When it comes to installing solar panels on flat roofs, specific mounting systems are indeed required to ensure optimal performance and safety. Flat roof installations differ from those on pitched roofs, primarily because they need additional considerations for panel angle and stability. The good news is that modern mounting systems are designed to accommodate these unique requirements, making solar energy a viable option for flat-roofed buildings.
Mounting systems for flat roofs typically involve either ballast or mechanical attachments. These systems are engineered to maximise solar exposure while ensuring the panels remain securely in place. By choosing the right mounting system, you can optimise your solar panel efficiency and longevity, all while maintaining the structural integrity of your roof.
Ballasted mounting systems are a popular choice for flat roofs as they do not require roof penetration. They use weights to hold the panels in place, minimising any potential for leaks or structural damage. This type of system is ideal for buildings where roof integrity is a primary concern. However, it is essential to ensure that the roof can bear the added weight of the ballast.
Alternatively, mechanically attached systems provide a more permanent solution by securing the panels directly to the roof structure. This method is particularly advantageous in areas with high wind speeds, as it offers greater resistance against adverse weather conditions. While this option might involve some roof penetration, it can be executed with minimal impact when performed by experienced installers.
Both systems aim to optimise the angle of the solar panels, usually set between 10 and 15 degrees, to maximise energy capture. By selecting the appropriate mounting system and ensuring proper installation, you can effectively harness solar energy even on a flat roof.
