Mounting system T-021.2

It is a ready-prepared kit for mounting panels on a corrugated sheet roof. It contains both the short aluminium rails that are placed across the corrugations and all the necessary screws, with gaskets that stop the water at the hole. There is no need to calculate what and how much to order: the set covers a small installation, of approximately 1 kW.

One kilowatt means in practice about 4 modules - the right size for a modest start or for a step-by-step extension of an existing system. The kit weighs only 5.4 kg, so it adds very little weight to the roof, far less than a solution with continuous 3-metre rails, while still keeping a controlled number of fixing points in the sheet. The system is of the click type and accepts mounting the modules both vertically and horizontally, the clamps being fixed on the short side of the panel. Note: the mid and end clamps are not included and are ordered separately, according to the thickness of the module frame, typically 30-42 mm.

Catalogue code XFS_T021.2, EAN 5904378627447, kit mass 5.4 kg. Contents: 10 short aluminium rails SMT-68/400 AL, with a size of 60x400 mm, and 60 self-drilling screws code M529, 6x25 mm, with double thread and EPDM washer, of A2 stainless steel. The rails are mounted at points across the corrugations of the sheet, one at each fixing point of the module, and the screws with EPDM washer ensure at the same time the fixing and the sealing of the penetration. Corab warranty: 10 years standard, extendable to 15 years by registration.

Who it suits

Suited to small installations, of about 1 kW, on industrial halls, workshops or outbuildings with trapezoidal sheet, including for extensions made in steps of 4 modules.

Terms explained

• 1 kW / 4 modules: The installation power covered by this kit; roughly, four ordinary photovoltaic panels.
• EPDM washer: A rubber washer fitted under the screw head, which is squashed when tightened and blocks the entry of water through the hole in the sheet.
• Mid and end clamps: The parts that press the panel onto the rail: the mid ones grip two adjacent modules, the end ones grip the last module in the row.

Technical specifications

Recommended applications

• Small photovoltaic installations on halls and outbuildings with trapezoidal sheet
• System extensions in steps of 1 kW
• Roofs where minimum added weight is wanted
• Fast mounting, with direct fixing into the corrugation of the sheet

Warranty

Corab policy for mounting structures: 10 years standard, extendable to 15 years by registration

Technical details

Specifications confirmed from the manufacturer's datasheet

Corab T-021.2 is a complete fixing kit for roofs covered with trapezoidal sheet, sized for a 1 kW installation, that is approximately 4 photovoltaic modules. The catalogue code is XFS_T021.2, EAN 5904378627447, and the mass of the kit is 5.4 kg.

The set contains 10 short aluminium rails SMT-68/400 AL, with a size of 60x400 mm, and 60 self-drilling screws code M529, 6x25 mm, with double thread and EPDM washer, of A2 stainless steel. The rails are mounted at points across the corrugations of the sheet, one at each fixing point of the module, and the screws with EPDM washer ensure the fixing and the sealing of the penetration in the covering.

The system is of the click type and allows both vertical and horizontal mounting of the modules, the clamps being fixed on the short side of the panel. The kit does not include the mid and end clamps, which are ordered separately according to the thickness of the module frame (typically 30-42 mm). Compared with the solution with continuous 3 m rails, this approach reduces the quantity of aluminium and the weight added to the roof, while keeping a controlled number of fixing points in the sheet.
