Manufacturing Anchor and Mounting Systems for PV

The role of anchor and mounting systems in small solar installations

For small solar installations—private homes, small commercial sites, local plants from 5–100 kW—anchor and mounting systems are just as critical as the panels and inverters themselves.

The correct selection and manufacturing of mounting hardware determines:

• the system’s resistance to wind and snow loads;
• the service life of structures without deformation and corrosion;
• the safety of people and the building;
• ease and speed of installation for the installer;
• the possibility of servicing and upgrading the plant.

In Tashkent and the regions of Uzbekistan, the climate creates high wind and temperature loads, so metal structures for solar/PV are subject to increased requirements for rigidity, weld quality, and corrosion protection.

Types of small PV installations and their mounting specifics

For small plants, three groups of solutions are most commonly used:

1. Ground-mounted solar installations

• Single-row or double-row frames on screw or driven piles.
• Low supports for small plots (private homes, mini-farms).
• Framed structures for carports and canopies.

Mounting specifics:

• working with soils of varying density;
• the need for precise frame geometry so panels don’t “play” or skew;
• increased sail effect—anchor quality and column rigidity are critical.

2. Façade solar installations

• Subsystems for vertical mounting of panels on walls;
• Brackets and rails for inclined façade mounting;
• integration with existing cladding (composite, porcelain stoneware, plaster, etc.).

Mounting specifics:

• limited load-bearing capacity of façade walls;
• the need to minimize heat loss and thermal bridges;
• neat appearance of the mounting hardware, no “excess” metal on the façade.

3. Small special-purpose solutions

• autonomous systems for video surveillance, communications, lighting;
• mini-plants on containers, pavilions, kiosks;
• hybrid solutions integrated into existing metal structures (canopies, pergolas).

Here the mounting hardware is most often non-standard, manufactured according to a custom specification and drawings.

Basic structural solutions: ground and façade systems

Ground structures

For small-scale ground-mounted PV systems, the following are used:

• Hangar / frame structure for panels—longitudinal and transverse beams, posts, diagonals;
• Columns and posts on screw piles, driven piles, or concrete blocks;
• Mounting rails for modules, with slots for clamps and bolts;
• Anchor nodes for attaching columns to foundations or piles.

The structure is selected based on:

• the number and type of modules;
• tilt angle and orientation;
• soil characteristics;
• requirements for the height and spacing of supports.

Façade structures

For façade mounting of small systems, the following are usually used:

• Brackets with various offsets (adjustable and fixed);
• Vertical and horizontal rails for mounting rails;
• Point anchors and embedded parts for load-bearing walls;
• Adjustment systems for plane and tilt angle.

The mounting hardware must evenly transfer the load to the building’s load-bearing elements and not damage the existing finish.

Material selection: carbon steel, galvanizing, stainless steel, combined solutions

Material is one of the key factors both for service life and cost.

Carbon steel with protective coating

Used for:

• columns, frames, load-bearing structures;
• support elements where rigidity and price are important.

Pros:

• high strength;
• availability and variety of profiles;
• optimal solution with proper protection.

Cons:

• requires high-quality corrosion protection (hot-dip galvanizing, powder coating, or a combination of both).

Galvanized steel

More often used for:

• mounting rails;
• medium-load brackets;
• small fasteners and connecting plates.

Pros:

• good corrosion resistance with proper zinc layer thickness;
• neat appearance.

Stainless steel

Used selectively:

• for critical nodes exposed to moisture and aggressive environments;
• for fasteners where appearance and durability are crucial (façades, visible elements);
• in areas with increased corrosion (near bodies of water, industrial emissions).

Cons—higher material and processing cost.

Combined solutions

In practice, small PV installations often use a combination:

• load-bearing frame—carbon steel with galvanizing or powder coating;
• rails and small fasteners—galvanized steel or stainless steel;
• visible façade elements—stainless steel or neatly painted metal.

The combination is always chosen according to the specification: load, service life, budget, appearance requirements.

Technological chain of manufacturing: from specification to finished kit

For the installer or customer, the key question is how an idea for a plant becomes a finished mounting kit that can be quickly installed on site.

A typical chain looks like this:

1. Collection of initial data and specification.
2. Engineering calculation and 3D modeling.
3. Preparation of production documentation.
4. Manufacturing of parts (laser cutting, bending, machining).
5. Welding and assembly of nodes (frames, brackets, columns).
6. Final treatment and corrosion protection.
7. Kitting, marking, and packaging.

All key decisions on design and materials are made at the calculation stage based on the specification. The more accurate the initial data, the fewer modifications are needed on site.

Machining: laser cutting, bending, drilling, milling

The quality of the mounting system is largely determined by the geometric accuracy of the parts.

Laser cutting

Used for:

• mounting plates, angles, connecting elements;
• façade brackets of complex shape;
• perforated elements for adjustment.

Advantages:

• high accuracy and repeatability of dimensions;
• clean cut, minimal finishing;
• the ability to quickly change geometry for a new specification.

Metal bending

Used for:

• U- and Z-shaped profiles;
• reinforced brackets and cantilevers;
• box-shaped elements to increase rigidity.

Bending allows sheet metal to be formed into elements with high rigidity while using less metal, which is important for both cost and structure weight.

Drilling, milling, thread cutting

Required for:

• holes for bolts and anchors;
• slots for adjustment and assembly;
• seats for embedded elements.

The accuracy of these operations directly affects installation speed: with high-quality machining, panels fit “to size” without on-site rework.

Welding and assembly of mounting nodes for solar panels

Welding is a key stage in manufacturing:

• frames and structures for ground systems;
• support posts and columns;
• complex façade brackets and frames.

It is important to ensure:

• sufficient weld cross-section for design loads;
• no burn-throughs or lack of fusion;
• minimal deformation after welding (especially on long beams and frames).

After welding, the following are performed:

• weld cleaning in visible areas;
• geometry control (angles, diagonals, flatness);
• preparation for galvanizing or painting.

For small projects, assembly of nodes into larger modules is often practiced so that ready-made frames, posts with flanges, and façade frames are delivered to the site. This reduces installation time and lowers the risk of errors on site.

Corrosion protection and final treatment

For Tashkent and the region, with intense sun, temperature fluctuations, and dust, metal protection is mandatory.

Main options:

Hot-dip galvanizing

• forms a durable protective zinc layer over the entire surface of the part;
• suitable for outdoor load-bearing structures (frames, columns, rails);
• ensures a long service life with minimal maintenance.

Powder coating

• used for visible elements (façade brackets, frames);
• allows color matching to the façade or building architecture;
• can be used as a standalone solution or in combination with zinc.

Combined schemes

• galvanizing + powder coating for increased durability and improved appearance;
• galvanized rolled stock + local painting of cut and weld areas.

The protection scheme and its thickness are also specified in the specification and affect cost and lead time.

What affects the cost of anchor and mounting systems

The final price of a mounting kit for solar panels is formed from several groups of factors. Below is a generalized table.

Therefore, without a detailed specification, it is not correct to quote even an approximate price. In practice, a calculation based on the specification is first performed, after which one or two options are offered in terms of materials and technology with different costs and lead times.

Lead times for small PV projects in Tashkent

Lead times depend on volume and complexity, but the general logic is as follows:

1. Engineering calculation and specification refinement—from 1 to several working days, depending on the completeness of the initial data.
2. Preparation of drawings and cutting maps—usually in parallel with solution approval.
3. Production of parts (laser cutting, bending, machining)—from a few days for small batches to several weeks for large ones.
4. Welding, assembly, corrosion protection—adds a few more days, taking into account logistics for galvanizing/painting.
5. Kitting, marking, shipping—1–2 days.

Lead times are additionally affected by:

• production workload and order queue;
• availability of the required rolled metal and consumables in stock;
• selected type of coating (galvanizing and complex painting schemes require more time).

Exact lead times are always given after calculation based on your specification and approval of the structural solution.

Typical mistakes when ordering mounting hardware and how to avoid them

1. Incomplete initial data on the site

Actual site dimensions, building height, façade specifics, soil type are not taken into account. The result is on-site rework, extra costs, and delays.

How to avoid: prepare measurements, site photos, a plan/scheme in advance, specify the base type (concrete, brick, aerated block, soil, etc.).

2. No clear specification for panel angle and orientation

Tilt angle and orientation directly affect the geometry of frames and brackets. Without this, it is impossible to correctly calculate loads and metal consumption.

How to avoid: fix in the specification the required angle or adjustment range, orientation to cardinal directions, and height constraints.

3. Choosing material based only on minimum price

Profiles that are too light or unsuitable coatings lead to deformation, corrosion, and extra costs after a few years.

How to avoid: discuss not only price, but also service life, operating conditions, and maintenance options. Consider 2–3 material options.

4. Ignoring wind and snow loads

Especially critical for ground systems and tall façades. Underestimating loads means a risk of structural failure.

How to avoid: specify the region, site exposure, and presence of tall buildings/barriers nearby in the specification. Require a calculation that accounts for loads.

5. Late involvement of the manufacturer in the project

When mounting hardware is “fitted” to already installed elements, compromises in geometry and materials are often necessary.

How to avoid: involve the manufacturer at the plant design stage, not after purchasing panels and inverters.

6. No allowance for adjustment

Rigidly fixed solutions without tolerances in height and plane complicate installation on a real site.

How to avoid: include adjustment slots, elongated holes, and the ability to fine-tune on site.

7. Inaccurate quantity and range of mounting hardware

Some items are missing on site, requiring additional purchases and rework.

How to avoid: request a specification from the manufacturer with a complete list of elements, including bolts, nuts, washers, embedded parts.

FAQ on manufacturing anchor and mounting systems for small solar installations

1. Can the same type of mounting hardware be used for roofs, façades, and ground installations?

Generally, no. Each base type (roof, façade, soil, concrete) requires its own anchoring scheme and elements. Unification of rails and some connecting hardware is possible, but load-bearing and anchor nodes differ.

2. What needs to be provided for a mounting calculation based on the specification?

Minimum set:

• object type (private house, office, warehouse, façade, etc.);
• photos and/or drawings of the object;
• planned plant capacity and number of panels;
• module type and dimensions;
• desired installation type (ground, façade, canopy, etc.);
• requirements for tilt angle and orientation;
• information about the base (soil, concrete, brick, etc.);
• preferences for material and coating.

3. Can existing metal structures be adapted for solar panels?

In many cases, yes: existing canopies, pergolas, and frames can be used by adding mounting rails and brackets. But the load-bearing capacity and condition of the metal must be checked, and sometimes the structure must be reinforced.

4. How critical is weld quality for small plants?

Even for small projects, weld quality is critical. Poor welds lead to cracks, deformation, and risk of collapse under wind loads. Therefore, welding must be performed according to approved drawings with geometry control.

5. Is it possible to order only manufacturing of mounting hardware without installation?

Yes, it is possible to manufacture a mounting kit according to your specification and drawings with subsequent shipment. In this case, special attention is paid to marking and kitting so that the installation crew on site can quickly understand the system composition.

6. How to account for possible future expansion of the plant?

At the calculation stage, you can provide for:

• extra rail length;
• the possibility of adding additional rows;
• reinforcement of some load-bearing elements;
• unification of mounting hardware for different module types.

This slightly increases the current budget but reduces costs during expansion.

7. What if there are no finished drawings, only a project idea?

You can start with a description of the object and requirements: capacity, installation type, site constraints. Based on this, a preliminary calculation is performed and a standard or adapted solution is proposed, after which working drawings are developed.

8. How important is geometric accuracy in manufacturing mounting hardware?

High accuracy means less on-site fitting, faster installation, and lower risk of panel damage. Therefore, laser cutting, precise bending, and dimensional control at each stage are used.

Submit a request for calculation

To get a calculation of anchor and mounting systems for your ground or façade solar installation in Tashkent and the regions, it is enough to prepare the initial data and send a specification.

For a prompt calculation, specify:

• object type and address (city/district);
• installation format: ground, façade, canopy, special solution;
• planned plant capacity and number of panels;
• type and dimensions of solar modules (if available);
• desired tilt angle and panel orientation;
