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.
Mount your solar panels on the ground structure. Connect your solar panels to your inverter. Maintain your ground-mounted solar panels. For our scenario, we consider the following: System size: A 2.4kW solar system of 6 x 400W solar panels. Total installation time: 2 to 3 days, including the building of the ground structure and solar frame.
Position Right: We set the panels on flat roofs at just the right angle to get the most sunlight. If you’re in the northern part of the world, the panels face south. If you’re in the south, they face north.
For pitched roofs, there are several solar panel mounting system options that work well, such as hooks and rails. These systems attach directly to the roof rafters. They provide a secure, stable base for panels.
You usually need planning permission to install flat roof solar panels. Solar panels on pitched or tilted house roofs rarely require planning permission because they fall under the ‘permitted development’ category – but that’s not the case with flat roof solar panels.
Prioritizing your roof for solar panel installation is often the most effective way to harness solar energy. Roofs typically offer the best angles and exposure for solar panels, leading to greater energy yields and long-term benefits compared to ground or vehicle-mounted systems.
