No two commercial developments are the same, and neither are their car parks.
From retail parks and office developments to healthcare facilities and education campuses, every project presents different challenges when it comes to parking layouts, vehicle movements and available space.
That’s why selecting the right solar canopy structure is just as important as specifying the photovoltaic system itself.
At SIG Building Solutions, we offer four core solar canopy designs, each engineered to suit different applications while maintaining functionality, maximising energy generation and integrating seamlessly into commercial developments.
Double Gull Wing
Ideal for large, high-capacity car parks
The Double Gull Wing is designed for projects where maximising energy generation is the priority.
Supporting up to six photovoltaic panels in portrait orientation, it delivers the highest kWp output per parking space within our canopy range, making it well suited to larger commercial developments with significant energy demands.
Typical applications include:
- Retail parks
- Distribution centres
- Business parks
- Hospital campuses
- Park and ride facilities
Where space allows, the Double Gull Wing offers an efficient way of generating substantial renewable energy while maintaining the full functionality of the car park beneath.
Double Mono
A balanced solution for conventional parking layouts
The Double Mono canopy has been developed for projects where simplicity, efficiency and performance are equally important.
Supporting up to five photovoltaic panels in portrait orientation, it has been designed to optimise solar generation while using materials efficiently, making it an excellent option for many standard commercial car park layouts.
It’s particularly well suited where:
- Parking bays follow conventional arrangements.
- South-facing orientations can be maximised.
- A clean, contemporary appearance is desired.
For many commercial projects, the Double Mono provides an excellent balance between performance, aesthetics and structural efficiency.
Single Row
Flexible by Design
Not every project requires large double-row canopies.
Where developments include smaller parking areas, phased installations or dedicated electric vehicle charging zones, the Single Row canopy provides a flexible alternative.
Supporting up to three photovoltaic panels in portrait orientation, it’s particularly suitable for:
- Smaller commercial developments.
- Staff parking areas.
- EV charging bays.
- Phased developments.
- Sites with varying gradients.
Its modular design also allows architects greater flexibility when integrating solar infrastructure into more constrained sites.
Hot Rolled Single Post
Designed for angled and herringbone parking layouts
Many commercial developments don’t follow traditional parking arrangements.
The Hot Rolled Single Post canopy has been specifically engineered for angled and herringbone parking bays, where conventional canopy structures may not be the most effective solution.
Using a hot-rolled steel column combined with a cold-formed canopy structure, it maximises the usable space beneath while maintaining excellent structural performance.
Typical applications include:
- Angled parking layouts
- Herringbone parking arrangements
- Premium commercial developments
- Sites where maximising manoeuvring space is important
Its open design also helps create a clean, uncluttered appearance throughout the car park.
Which Canopy Is Right for Your Project?
The answer depends entirely on your project.
Parking layouts, vehicle movements, structural requirements, energy targets and future electric vehicle infrastructure all influence the most appropriate solution.
That’s why every project begins with understanding the wider development before selecting the canopy structure.
Rather than adapting a standard product to suit a site, our team works with architects and designers to recommend the canopy solution that best complements the layout, functionality and long-term objectives of the project.
Which Canopy Is Right for Your Project?
Choosing a solar canopy is about more than selecting a structure.
It’s about designing renewable infrastructure that integrates seamlessly into the wider development, supports sustainability objectives and delivers long-term value for clients.
Whether you’re developing an initial concept or progressing a detailed design, our specialist team can help you identify the most appropriate canopy solution for your project.
