Solar Canopy Structures are becoming an increasingly popular way for organisations to generate renewable energy while making better use of existing car parks and paved spaces. However, successful installations depend on more than simply mounting solar panels above a parking area. The design of the supporting structure is what ultimately determines how well the system performs.
At SIG Building Solutions, design quality is central to every Solar Canopy Structure we produce. From understanding the unique characteristics of each site to selecting the right materials and structural configuration, careful design ensures that every project delivers both performance and long term reliability.
Designing Around the Site:
No two car parks are the same. Differences in layout, gradients, parking arrangements and traffic flow all influence how Solar Canopy Structures should be designed.
During the design stage, several key factors must be considered. The size and shape of the parking area will determine how the canopy structures are positioned. Bay orientation can influence the direction of the solar panels and the energy output that can be achieved. In many cases, access routes and existing infrastructure such as lighting, drainage or underground services must also be factored into the design.
By taking these variables into account, Solar Canopy Structures can be designed to integrate naturally into the existing environment while maintaining the functionality of the space below.
Meeting the Needs of Each Project:
Every organisation has different priorities when investing in Solar Canopy Structures. Some sites focus on maximising energy generation, while others prioritise flexibility for electric vehicle charging infrastructure or the efficient use of available space.
At SIG Building Solutions, we approach each project with a flexible design philosophy. Rather than applying a single standard structure, we offer a range of canopy configurations that can be adapted to suit different site layouts and energy goals.
Our Double Gull Wing design supports a higher number of photovoltaic panels and delivers strong energy output across larger installations. The Double Mono option is often used where south facing layouts allow for efficient generation with minimal material use.
Single Row structures provide a flexible solution for modular installations and EV charging locations, while the Hot Rolled Single Post design is particularly suited to angled or herringbone parking bays where maximising usable space beneath the canopy is essential.
This range allows us to design Solar Canopy Structures that are tailored to the specific needs of each project.
Materials That Support Strong Design:
Design quality also relies on selecting the right materials. Structural integrity and long term durability are essential for outdoor infrastructure that must perform reliably for decades.
SIG Building Solutions engineers its Solar Canopy Structures using high grade Tata Steel, ensuring strength and durability across a range of environmental conditions. The use of premium steel allows our structures to withstand wind loads, snow loads and the day to day demands of busy commercial environments.
Manufacturing takes place at our facility in Carlisle, where advanced fabrication processes allow us to maintain strict quality control throughout production. By combining strong design with high quality materials, we ensure every Solar Canopy Structure is built to perform.
Designed and Manufactured in the UK:
SIG Building Solutions is a specialist UK manufacturer of Solar Canopy Structures and part of SIG plc, a FTSE listed construction products group. This allows us to combine the expertise of a dedicated steel fabrication team with the confidence of working with a well established national organisation.
Producing our Solar Canopy Structures in the UK gives us full oversight of the manufacturing process while supporting shorter supply chains and consistent product quality.
For our customers, this means structures that are designed with care, manufactured to high standards and delivered with reliability.
Quality Design That Delivers Long Term Value:
As Solar Canopy Structures continue to play a growing role in renewable energy and EV charging infrastructure, the importance of thoughtful design becomes even clearer.
By considering site conditions, project goals and material performance from the outset, high quality design ensures that Solar Canopy Structures deliver reliable performance while enhancing the spaces in which they are installed.
At SIG Building Solutions, design quality is not simply a stage in the process. It is the foundation of every Solar Canopy Structure we create.
