PV mounting systems

What is a PV Mounting System suitable for ground installations comprised off?

A PV Mounting System is comprised of special alloy aluminium or galvanized steel profiles. It is fixed to the ground using a galvanized pole to avoid corrosion over the course of time or via a concrete base-frame.

What are the benefits of using a mono pole PV mounting system?

By using a Mono Pole Mounting System, the installation time required is reduced significantly (by about 50% comparative to that required for a double pole system. In addition, the construction costs are substantially lower as compared to the costs of constructing a double pole system. Of course, in saying so, the double pole system is favored for installations where a single pole system is not feasible (e.g. very unstable surfaces, etc).

Is the mono pole system resistant to snow & wind?

The mono pole mounting system is designed to ensure its adequate stability in accordance with the rules set and outline by Eurocodes 1-3-8-9, which pertains to snow volume and wind pressure. Subsequently, it is as equally effective as other types of mounting systems (e.g. double pole, etc).

How are the PV panels connected to the Mounting System?

The PV panels are connected with the mounting systems through special links known as clamps. The size dimensions of the clamps are equivalent to the size of the PV panel, that is, the actual width of the panel.

Are the mounting systems covered by a guarantee?

VIGOR offers a 20 year material guarantee for the aluminium profile & accessory components that comprise the system.

Can PV panels of different shapes and sizes be applied?

VIGOR’s PV Mounting Systems support all available monocrystalline or polycrystalline PV panels, regardless of the width of the profile (35/40/45/50mm).

On what type of surface can I install a PV mounting system?

The mounting system can be installed on all types of surfaces. However, according to the requirements of the surface and the geotechnical study or the pull out test, the method of support and the type of support is adjusted accordingly.

When is a mono pole or double pole mounting system installed by simple pile-driving method and when is the concrete pile-driving method is used?

The pile-driving method for a mono or double pole mounting system depends on pull-out test or geotechnical study results as performed by certified personnel. If these results satisfy the minimum requirements of the relevant static analysis, the simple pile-driving method is suitable. Otherwise, the concrete solution is necessary.

What is the maximum penetration depth of the pole?

The maximum depth of the pole’s penetration into the surface is dependent on the results of the geotechnical study and the pull out test. It must satisfy the pole’s extrusion requirements, and generally falls within the range of 1.5m - 2.5m.

What material is the pole made out of?

The pole is made of steel (quality S235), hot-dipped galvanized at 80μm at the very least, and in order to avoid its corrosion when it comes into contact with the ground’s surface.

Can I use a pole with a different cross section and length?

The cross section and length of the pole are immediately relative to the design and the mounting system’s static analysis. In order to use a pole of different geometrical characteristics, the endorsement of the technical team is also required.

What is the maximum permissible angle of the PV panels and how is this defined?

The angle of the PV panels is directly related to the static study of the mounting system, the PV panel type as well as the geographic location of the PV station under construction.

For VIGOR’s mono pole mounting systems, the maximum angle is 30ο for the systems with product codes MP-1020 & MP-1120, whereas for the system with product code MP-1121 the angle is 35ο.

How is the mounting system installed on a plot of land that has a steep angle on the East-West axis (E-W)?

In the event that the land plot has steep inclines on the E-W axis (over 2-3 degrees), then landscaping works are required so as to ease the angle of the land, and simultaneously the row layout of mounting systems will be shorter than the maximum 100m.

What is the maximum width of the mounting system row layouts?

The maximum width of the mounting system rows varies as dependent on the type of the mounting system (that is, mono pole or double pole, etc), the static analysis which has been administered as well as the quality of the land plot where the project installation will take place (e.g. angle, the surface hardness, etc). For the VIGOR systems MP-1020, MP-1120 & MP-1121, the maximum width is 100m.
