Fitting flat roof solar panels presents a host of compelling advantages. Firstly, the unobstructed orientation of flat roofs allows for optimal sunlight exposure, maximising energy generation potential. Additionally, the installation process is relatively straightforward and cost-effective, utilising existing space without altering the building’s aesthetics. By harnessing clean and renewable solar energy, flat roofs equipped with solar panels contribute to reduced utility bills, decreased carbon footprint, and overall environmental sustainability, making them a smart choice for both energy efficiency and economic viability.

BauderSOLAR is a flat roof photovoltaic mounting system that is attached to the roof without penetration of the waterproofing system or roof deck. The systems are designed to be used in conjunction with our single ply or bituminous membrane waterproofing solutions and are lightweight at 9-12.5kg/m2, depending on the module selected. Only suitable for Bauder roofs.

Bauder Flat Mounting

Van der Valk solar mounting is a flat roof ballasted system, meaning no roof penetrations are required to fit the mounts. The solar mounting systems for flat roofs from Van der Valk Solar Systems have been developed with all due attention for roof and wind load, so they comply with the highest safety standards.

Can you have solar panels on a flat roof

Yes, solar panels can be fitted to a flat roof. Typically solar photovoltaic (PV) panels are installed using a ballasted metal frame. The installation process involves constructing a metal triangular frame that is weighted down with blocks. This design provides stability and helps distribute the weight of the panels evenly across the flat roof surface.

The panels are then pitched at an angle of around 10 degrees. This pitch is chosen for several reasons.

First, it is not recommended to install panels completely flat on a roof due to fire risk. Allowing for a slight pitch helps minimize the risk of fire by promoting better heat dissipation and reducing the accumulation of debris that could potentially catch fire.

Furthermore, the 10-degree pitch is chosen for optimal energy generation. While completely flat panels may not capture sunlight as efficiently, a modest tilt can enhance the panels’ exposure to sunlight, improving their overall performance and energy yield.

Additionally, the pitch helps prevent the accumulation of dirt and debris on the panels. When solar panels are completely flat, dirt tends to accumulate and settle, reducing their efficiency over time. A slight pitch encourages debris to either fall off or be washed away by rain, maintaining the panels’ effectiveness in capturing sunlight.

It’s worth noting that fitting solar panels to a flat roof requires careful consideration of structural integrity, load distribution, and adherence to safety regulations. The ballasted metal frame method is a common and effective approach for such installations, providing a secure and reliable solution for harnessing solar energy from flat rooftops.
