2024 PV Panel Clamp Technology Innovations: From Bottom Mounting to 3D Printing, the Industry Embraces Diversified Breakthroughs
2025-01-05
In 2024, the PV panel clamp industry witnessed multiple breakthrough innovations – from Energy5‘s bottom‑mounting patented design to Sunlight New Energy’s rotating‑clamping technology, from open‑source explorations of 3D‑printed clamps to the application of Zn‑Al‑Mg coated materials. The industry is rapidly moving toward more efficient installation, more reliable clamping, and more environmentally friendly materials.
1. Installation Method Innovation: Bottom‑Mounting Clamps Lead an Efficiency Revolution
Energy5: Poland‘s First Bottom‑Mounting Clamp, Patented
In March 2024, Polish PV installation solution provider Energy5 launched a patented set of bottom‑mounting end clamps and mid clamps, claimed to be the first clamp solution in Poland – and even internationally – that allows modules to be fixed from the bottom side.
Technical Highlights:
| Feature | Description |
|---|---|
| Bottom‑mount design | Eliminates the need to hold clamps and screws from above; installers can pre‑assemble on the ground or from scaffolding |
| Spring‑loaded adapter | Compressing the spring allows easy positioning of the clamp into the corresponding holes of the rail |
| Socket wrench tightening | Special hole design enables precise adjustment and fastening with a socket wrench |
| No walking on modules | Removes the risk of installers stepping on modules, reducing micro‑cracks and damage |
| Patent protection | The solution has been registered with the Polish Patent Office (UPRP) |
Cezary Rutkowski, Technical Director at Energy5, stated: “Clamps mounted from the bottom of the module not only speed up installation, but also simplify maintenance and increase the safety and durability of the entire system. Customers who have chosen our new clamps are enthusiastically continuing to use them in subsequent projects.”
2. Material & Process Breakthroughs: 3D Printing and High‑Performance Coatings
Western University: 3D‑Printed Clamps Achieve 66% Cost Savings
In May 2024, a research team at Western University (Canada) published a groundbreaking study in the journal Renewable Energy, developing four designs for wood‑based PV mounting structures using 3D‑printed clamps…
