The Solar Mid Clamp is an anodised aluminium clamp that locks two adjacent panels to one rail. Its stainless steel bolt holds the inner edges flush, which keeps panel spacing even in wind.
Installers order this solar panel rail mid clamp in bulk for rooftop arrays across South Africa. You’ll find it in our Mounting range with rails, brackets and end clamps.
Solar Mid Clamp Benefits On Site
- Firm inner-edge fixation stops panel slippage under heavy wind loads.
- Anodised aluminium body copes with extreme heat and coastal humidity.
- Quick-fit design cuts fitting time on IBR, tile and corrugated roofs.
Loose panels can shift under wind load or heat expansion and knock a whole row out of line. Correctly tightened, each solar panel clamp keeps both neighbouring panels stable and level.

Where A Solar Panel Mid Clamp Sits
Mid clamps go between panels, gripping the frame edge of each neighbour. At each row end, the Solar End Clamp takes over, because only one panel edge needs holding there. Neither clamp replaces the other, so every row needs both types.
Count one solar panel mid clamp per panel gap on every rail when you plan an order. Installers quoting large arrays use this tally to order solar mounting clamps in one batch.
Rail Compatibility And Frame Fit
This solar clamp fits standard rails like the P2000 3.2m from our solar panel rails range. Those rails sit on IBR solar brackets or Corrugated Roof Solar Mounts. Rail lengths join with the Solar Panel Rail Link.
The stainless M8 Allen cap screw locks each clamp into the rail channel for a firm hold. It isn’t confirmed for unistrut channel or frameless panels, so check those layouts with us first.
Frame Height Check
One clamp height suits one frame thickness, so measure your panel frame before you order. Match the frame to this mid clamp size, with its 20 mm overall height and 14 mm opening. We tell installers to tighten each bolt evenly, so panels on both sides sit flush and aligned.
Best Use Cases By Buyer
- Rooftop installs for residential, commercial and factory arrays.
- Homeowners adding panels to an existing system.
- Farms powering pumps and workshop tools from shed roofs.
Businesses replacing worn fasteners should match new clamps to the existing rail profile and frame height. Keeping spare solar panel accessories like these on hand speeds up repairs after storms. Factory rooftops with long rows need many solar panel mounting clamps, so bulk orders save repeat trips.
Warranty Compliance And Delivery Trust
The clamp carries no product certification, because aluminium and stainless steel bolts are materials, not approvals. Corrosion and weather resistance are site listings, with no salt spray result claimed yet.
SANS 10160-3 sets the wind actions used to design rooftop structures. Clamp spacing and fixing remain the installer’s responsibility, guided by this SANS 10160-3 wind research.
SANS 10142-1 governs the electrical installation, including earthing of the array. A registered person issues the Certificate of Compliance under the Electrical Installation Regulations. That certificate is never supplied with the clamp.
