We’ve designed the support feet that sit beneath the main structure, to fix directly into concrete ballast using chemical anchors. There are 2 main fixings per support foot, which provides a secure hold into the concrete foundation.
Although this is the main method of connecting to ballast, there is an alternative whereby a concrete mixture is poured around the support feet to create a secure hold.
These foundations can be dug into the ground with a layer of soil applied over the top to hide them from view, or can simply be left to sit on top of the existing ground.
This solution is perfect for ground conditions that make it difficult or impossible to either screw or drive other systems into place. Instead, the frames are securely connected to concrete ballast to weigh it down against the wind forces acting on the system.
The benefits of ground mounted solutions over roof mounted options, include the ability to set the solar panels at the optimum orientation and angle in order to maximise the system’s energy generation. They can also make use of land that is otherwise left empty, such as, fallow land, brownfield sites and even landfill sites. They offer easy access to the array and allow regular maintenance without the need for any specialist lifting equipment.
Our standard structure is designed to support 2 solar panels high in the portrait orientation, as this allows more space within the array for more solar panels. There isn’t a limit to how many solar panels can be installed in a single line.
We know that sometimes ground conditions can be problematic, whether it’s because of a slight incline or just the simple fact of the land not being even. To get around this, we’ve ensured that our Ground Anchor system allows greater adjustability in the height of the individual posts of the frame, as well as the positioning of the posts within the Ground Anchors. The framing is designed to work with most solar panels, allowing it to universally suit most projects and with no limit to how long you can make the array, it allows you to make the most of the space available.
We add wind bracing in the form of tension cable to the back of the frames at certain intervals along the solar panel row, to provide added stability against lateral movement. We calculate where you need to place these wind bracing sets and they’ll be marked on the drawing layouts that we provide you at the point of order.
Our standard product allows the solar panels to be mounted in a portrait orientation, which we carry in stock and can often facilitate a next day delivery service straight to your site (subject to availability and delivery location). This module orientation allows more solar panels to be installed on the land allocated, however, if a landscape option is preferred, we can create a bespoke frame for your project.
We favour the hot-dipped method of galvanising the steel elements of our ground mounted systems. This is because, compared to electro-galvanising, it allows us to specify the thickness of the protective coating. The average thickness of steel parts in other industries is around 200g/m, but at Sunfixings we double this, so that this protective coat is a minimum of 400g/m and therefore, ensuring a long lasting life for our systems.

It’s our strong belief that correct practices should be applied and followed up that’s why we calculate each project, whether it’s 2kWp or 2MW, to ensure that it’s safely and professionally designed. We support our calculations and mounting systems with our 10 year warranty.
Our module clamps are universally suitable for all solar panel depths and what’s more, they’ll arrive to you pre-assembled, allowing you to keep on schedule when it matters the most. They’re also available in black.
