Sometimes a ground mounted system is required to sit lower to the ground and reduce its overall height, whether this is because of aesthetic or planning permissions reasons. So we’ve taken some elements from our other system to create an elevated frame suitable for holding a single solar panel high. This allows us to easily adjust the height and angle of them.
We’ve specifically designed the connection of this frame to be as universal as possible, in order to suit a variety of different situations.
This system can easily be screwed into ground that has a high clay content using our Ground Anchors. They connect to the elevated frame via a T shaped adapter. There’s a layer of UV resistant EPDM applied to this in, in order to separate its galvanised steel material from the aluminium elevated frame to avoid any chemical reaction from occurring.
We recommend hiring a 2.5 tonne cylinder head hydraulic auger unit, with a reverse option for installing the Ground Anchors. Sometimes the ground may need a little more pressure applying to it and for this, a 4-5 tonne auger unit is better suited. We’ll lend you an auger adapter that fits the auger unit to help screw them in.
For instances where the ground is too hard to screw into, a different set of support feet can be used, which allow the system to fix into concrete ballast with chemical anchors. The ballast can be poured into a ditch and then covered with a layer of top soil to hide it from view, or it can use pre-cast concrete blocks that are simply put directly on top of the ground. Either way, we can advise you on the exact weight and dimensions that you need for your project to withstand the wind forces in that location.
We locally produce the elevated frames in the UK, which allows us to tailor them to any specification. So whether you need 900mm or 200mm between the solar panel and the ground level, we can incorporate this, together with any angle required, to suit your individual 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.

So we’ve pre-assembled the smaller components, such as the Fixed Connectors, which connect the lengths of mounting rail together, so that they’re ready to be simply slotted into the mounting rail profile.
Sunfixings Clamp XL fully assembled, Silver Mill Finish and Black Anodised are suitable for 32mm, 35mm, 40mm PV Module Thickness. For PV Module thickness beyond this range, Sunfixings offer alternative and complete Middle and End Clamp Mounting Solutions.
