There’s a huge demand for renewable energy right now, and it’s only going to grow. Both energy suppliers and governments are prioritising sustainability, and solar energy is playing a big part in that. But for solar to provide the long-term energy solution the world needs it to be, solar fields need to have the right infrastructure. And that’s why screw piles are proving to be such an important asset for the solar industry.
The Role of Screw Piles in Solar Panel Infrastructure
Why foundations matter for solar arrays
Wherever they’re installed, solar panels must be perfectly stable and properly aligned to support the best possible energy production. So, the foundations need to stay strong for decades, regardless of changing weather or soil conditions. But with commercial developments, you also need the flexibility to scale, move, or change your solar setup. That balance of stability and flexibility is hard to strike.
While traditional concrete foundations can be labour-intensive, environmentally damaging, and slow to install, screw piles offer a quicker, cleaner, and more sustainable alternative.
What are screw piles?
Screw piles, also known as helical piles, are basically giant screws. Steel shafts with carefully placed helical flights, which secure them into the ground, they’re rotated into place. This means that they can anchor structures securely without the need for excavation, concrete, or subsequent curing time. They’re a popular choice for a whole range of construction projects, whether commercial or DIY. But they’re particularly suited to supporting solar infrastructure because they’re strong, fast to install, and versatile.
What are the advantages of using screw piles for solar projects?
Environmentally friendly installation
Unlike concrete foundations, you can install screw piles without any excavation. This means that very little soil is displaced during the build process. And that reduces the impact on the local environment.
Rapid deployment
Time matters in any large-scale construction project because the longer it takes, the more costly it becomes. When installing screw piles for solar installations, you can significantly reduce completion time.
Installation anytime and almost anywhere
There aren’t many conditions for which screw piles can’t provide a solution. Unless your site is on solid rock or gravel, screw piles can provide a viable solution. Even in flood-prone areas – which is why they’re so popular with solar developers across Canada. And because they don’t need to set, they can be used in all weathers at all times. Rain, frost, wind, snow – if you can get to your site, you can start installation.
Reusability waste
Removing concrete requires highly environmentally disruptive groundworks. And although concrete can be reused as aggregate, it doesn’t directly benefit the company that is removing it. Screw piles can be easily removed and reused. This makes them ideal for temporary or mobile solar units and can save the business money. And when they do reach the end of their lifecycle, the steel components are fully recyclable.
Precision and stability
Solar panels need to be precisely orientated for maximum efficiency. Screw piles provide the stability they need to stay aligned and secure for decades with minimal maintenance. But more than that, if you’re working with uneven ground, you can use screw piles to ensure precision levelling.
Solar energy is a vital part of fixing the sustainability problem. Screw piles support that vision. They’re versatile, flexible, and durable, offering long-lasting performance where it’s needed most.
