- General structure 35 Nw/mts.
- NXT-AUA 30/46 universal clamps 15 Nw/mts.
- NXT-CLAMP and NXT-CLAMP PRO clamps 20 Nw/mts.
2 - What is the maximum number of modules per array of each solution?
- Systems with rails max. 20 modules.
- NXT-MINI max. 12 modules.
- NXT-NANO max. 6 modules.
- NXT-CLAMP PRO 4 max. 10 modules.
- MIRROR U max. 12 modules
- MIRROR V max. 12 modules
3 - Do your Mid clamps also work as End Clamp?
Our clamps are universal, that is to say, they work both as end clamps and as central clamps, apart from being compatible with module frames from 30mm to 46mm and having an integrated grounding system.
4 - What is the maximum wind resistance of each solution?
- NXT-PV RACK System up to 246 km/h.
- NXT-MIRROR U System up to 215 km/h.
- NXT-MIRROR V System up to 215 km/h.
- NXT-PORT System up to 215 km/h.
- NXT-PORT System up to 215 km/h.
- NXT-NANO System up to 190 km/h
- NXT-CLAMP 2.0 System up to 200 km/h.
- NXT-CLAMP PRO System up to 180 km/h (for 454 W modules).
5 - Can I install the single or double row solution without drilling the slab?
In order to make a correct installation and guarantee wind resistance, it is necessary to anchor directly to the concrete slab.
6 - What is the minimum thickness for trapezoidal sheet installation?
The ideal minimum thickness of the sheet should be gauge 26.
7 - Can I raise the Aluminext structure?
It is possible to make an installation with an initial height of up to 1 meter, always taking care not to exceed the final height of 2m.
8 - Can I make an installation with an inclination on a laminated roof?
The maximum inclination should be 10º with direct anchorage to the pole that supports the sheet.
9 - What type and size of anchorage is recommended for the proper fastening of the Aluminext supports to the concrete slab?
Expansive anchor of ⅜”.
10 - How can I determine the amount of wind bracing in the NXT-PV RACK arrangement?
It is recommended 1 windbreak per 2 free spans, it is necessary to position side and rear windbreaks.
11 - What is the maximum overhang I can have in the Aluminext structure?
The maximum overhang allowed is 35 cm.
12 - What factors should I consider when choosing between the NXT-CLAMP PRO 4 and NXT-CLAMP 2.0?
The NXT-CLAMP 2.0 allows to orient the panel horizontally and vertically, in case of the NXT-CLAMP PRO 4 it allows to orient the panel only in horizontal orientation. The selection of each one will depend on the available space and the orientation of the lamination.
13 - What is the maximum panel inclination in the Aluminext solutions?
The NXT PV RACK solution allows an inclination of up to 30º as long as the final height does not exceed 2m.
