The 40x40 aluminium rail is the fundamental structural component for building photovoltaic mounting systems. This product is a load-bearing profile used to mechanically support solar panels on roofs or ground-mounted structures.
The length is chosen simply by selecting the desired quantity: 1 unit corresponds to a 1.19 m rail and 2 units correspond to a 2.38 m rail. Each quantity ordered corresponds to a rail delivered in one piece, adjusted according to your selection. Please note that the maximum length for transport is 2.40 m.
This accessory is specifically compatible with quick end and middle clamps as well as k2-type fixing hooks. This device creates a rigid fixing base that can be integrated into any mounting ecosystem requiring a 40x40mm section for increased resistance to climatic loads.

We ship rails up to 2.40 m long to meet transport constraints. Beyond this length, several rails can be assembled using joints, guaranteeing perfect mechanical continuity.
Corresponding quantities :
- 1 unit = 1.19 m of rail
- 2 units = 2.38 m of rail
Each unit corresponds to a single, precision-cut rail.
Maximum shipping length: 2.40 m
The rails are installed in several stages: fixing the hooks, levelling, laying the rails, joining them if necessary, then finally tightening the solar panels. To help you, here's an explanatory video:
Are these rails compatible with all solar panels?
Yes, the 40x40 mm profile is compatible with most standard photovoltaic modules on the market.
Can I connect several rails together?
Yes, simply use the special connectors to obtain the maximum length for your installation.
Is the rail weatherproof?
Absolutely. Anodised aluminium is exceptionally resistant to corrosion, rain, snow and UV rays.
Are these rails suitable for self-consumption installations?
Yes, they are ideal for domestic, commercial and professional photovoltaic installations.
40x40 aluminium mounting rail for solar panels - length 1m by Wattuneed is available in our Mounting systems catalog. Product weight: 1.3 kg. Reference: 0200.
