Flat roof systems require a specialized approach when it comes to solar installations. The solar panels need to be correctly angled to maximize sun exposure, which may necessitate the use of tilt legs, triangle mounts, or a ballasted racking system.
This can also help to estimate solar system size. Opt for an angled mounting system on your flat roof to optimize sunlight exposure. This system positions panels at an angle, similar to tilted roofs, to capture more sunlight throughout the day. You’ll give your panels a sunbathing spot, ensuring they soak up as much energy as possible.
You can technically lay the panels down on a flat roof – just as you would on a pitched roof – but this will restrict them from absorbing as much sun as possible, and might also lead to water damage. That’s why you need to install a framing system, to tilt your panels towards the sun.
While the upfront installation cost might seem high, weigh it against the significant savings on energy bills and the environmental advantages over time. Installing panels involves penetrating the roof, potentially causing leaks if not sealed properly.
Thanks to recent changes to permitted development rules, most installations on flat roofs won’t need solar panel planning permission. So long as the panels aren’t visible from the street and don’t exceed 200mm above the roof, they should be covered under permitted development rights.
Flat panels receive less direct sunlight and experience fewer extreme temperature shifts, which could potentially extend their lifespan compared to those installed at optimal angles for maximized production. This reduced exposure helps prevent overheating, thus enhancing the overall longevity of your panels. One big perk of flat roof solar systems?
Installing solar panels on a flat roof is possible and practical. Contrary to common belief, flat roofs offer an excellent platform for solar installations. The process involves mounting the panels at an angle to optimize sun exposure. However, …
