PV Mounting Systems for Solar Panels in Tashkent

The role of PV mounting systems in PV projects in Tashkent

For PV installers, developers, and industrial consumers in Tashkent, PV mounting is not just “metal under the panels.” The selected mounting system determines:

• the service life of the plant and maintenance intervals;
• actual generation (tilt angle, orientation, shading);
• installation speed and labor cost;
• the possibility of expanding or upgrading the facility.

With identical modules and inverters, two plants can differ in CAPEX and OPEX precisely due to the metal structures: frame, mounting rails, support trusses, and connection points to the roof or foundation.

Climate and loads in Tashkent: what to consider when choosing mounting systems

Conditions in Tashkent and the regions of Uzbekistan impose specific requirements on PV mounting:

• High insolation and temperature. In summer, metal heats up significantly; thermal expansion, expansion gaps, and coating selection are important.
• Wind gusts and dust storms. For ground-mounted arrays and carports, wind loads are critical; for roofs, anchoring quality and sealing are key.
• Rare but intense precipitation. Snow loads are lower than in northern regions, but local snow drifts and heavy rains must be considered when calculating trusses and tilt angles.
• Dust and aggressive environment. In industrial zones and near highways, corrosion resistance is crucial: choosing between galvanized steel, stainless steel, and aluminum.

Therefore, standard “universal” solutions do not always work. Optimal PV mounting for a roof in central Tashkent and for a ground-mounted array in a dusty industrial zone means different structures and different coatings.

Main types of PV mounting: roofs, carports, ground-mounted arrays

For commercial and industrial facilities, three groups of solutions are most commonly used:

1. Roof systems

   • flat roofs (concrete, profiled sheet);
   • pitched roofs (metal, standing seam, slate, sandwich panels).

2. Carports and canopies for PV plants

   • parking for employees and visitors;
   • canopies over process areas, warehouses, walkways.

3. Ground-mounted arrays

   • single-row and multi-row structures;
   • fixed tilt or adjustable.

Each type requires its own approach to metal structures: trusses, columns, mounting rails, connection nodes, base plates, bracing and struts.

Materials and coatings: steel, stainless steel, aluminum

When choosing PV mounting, it is important to understand what the structure is made of and how it is protected against corrosion.

Carbon steel with protective coating

• Pros: high load-bearing capacity, design flexibility (trusses, columns, non-standard nodes), optimal price/rigidity ratio.
• Cons: sensitive to coating damage, requires quality control of welding and painting.
• Applications: frames for ground-mounted arrays, carports, load-bearing metal structures for large panel rows.

A combined approach is often used: load-bearing elements are steel with protective coating, while small fasteners and clamps are stainless steel or aluminum.

Stainless steel

• Pros: high corrosion resistance, stable appearance, service life matching the entire life of the PV plant.
• Cons: higher material and processing cost.
• Applications: critical nodes, fasteners, clamps, brackets in aggressive environments (industrial zones, near roads, in dusty areas).

Aluminum

• Pros: low weight, easy installation, corrosion resistance.
• Cons: lower rigidity compared to steel, limitations on span length and loads.
• Applications: mounting rails, clamps, elements of roof systems where installation speed and minimal roof load are important.

Material selection is always tied to the technical specification: type of facility, loads, expected service life, appearance requirements, and budget.

Factors affecting the cost of PV mounting

It is impossible to quote an exact price without a technical specification: the final estimate is formed from dozens of parameters. Below are the key factors.

To receive an accurate commercial offer, it is important to provide a clear technical specification from the very beginning — more on this below.

Roof solutions: flat and pitched roofs

Flat roofs (concrete, membrane, profiled sheet)

For flat roofs in Tashkent, the key questions are:

• permissible load on the slab or profiled sheet;
• type of waterproofing and fastening method (ballast, anchors, combined schemes);
• required tilt angle and orientation to the cardinal directions.

What is important to consider when choosing mounting:

• the possibility of installation without damaging the waterproofing or with a controlled number of penetrations;
• convenience of roof maintenance (walkways, access to equipment);
• minimizing wind sail effect under wind loads.

Pitched roofs (metal, standing seam, sandwich panels)

For pitched roofs, PV mounting is selected for the specific type of roofing:

• standing seam clamps without drilling;
• special hooks for metal tiles and slate;
• fastening to purlins through profiled sheet with sealing.

Critical points:

• high-quality sealing of fastening points;
• load distribution across the rafter system or purlins;
• unification of mounting rails and clamps to speed up work.

When calculating according to the technical specification, roof dimensions, rafter/purlin spacing, roofing type, and location of service penetrations are taken into account.

Carports and canopies for PV plants: design and installation

PV carports in Tashkent are in demand at business centers, shopping malls, gas stations, logistics and industrial sites. These are metal structures that simultaneously provide parking and power generation.

Main elements of a carport:

• columns and foundations (or embedded parts in an existing base);
• trusses and purlins for mounting rails;
• mounting rails and clamps for panels;
• drainage and, if necessary, additional cladding elements.

What affects the choice of mounting and structure:

• span width and clearance height (requirements are higher for truck access);
• parking layout (single-sided/double-sided, angled or perpendicular);
• wind loads and site exposure;
• appearance requirements (powder coating in corporate colors, concealed fastening nodes).

For carports, combined solutions are often used: load-bearing frame made of steel, mounting rails and small fasteners made of aluminum or stainless steel. This allows budget optimization without sacrificing service life.

Ground-mounted arrays: when they are more cost-effective than roofs and carports

Ground-mounted arrays for solar panels are relevant when there is a free site and no height restrictions.

Advantages of ground-mounted arrays:

• optimal tilt angle and orientation without being tied to a roof;
• easy maintenance and cleaning of modules;
• the possibility of dense layout of the PV field.

Specifics of choosing mounting and metal structures:

• foundation type (pile supports, driven posts, concrete blocks);
• support spacing and panel row height;
• need for tilt adjustment (fixed or seasonal adjustment);
• corrosion protection depending on soil composition and humidity.

For industrial consumers and developers, it is important at the technical specification stage to determine what is more critical: minimum CAPEX or scalability and ease of maintenance. This determines the array scheme, profile cross-sections, and type of mounting.

Typical mistakes when selecting and ordering PV mounting

Even experienced players in the PV market in Tashkent face recurring mistakes. Below are 5–7 typical situations to avoid.

1. No complete technical specification at the start
   The order is limited to the phrase “mounting for 500 kW on a roof,” without plans, photos, or load data. The result is metal overconsumption or, conversely, underdesigned structures and on-site rework.

2. Trying to use a “universal” solution for all facilities
   Mounting that worked on one roof type is transferred to another facility with a different base and wind conditions. The result is sealing issues, complicated installation, and extra work.

3. Underestimating wind loads
   In exposed locations (city outskirts, industrial zones, highways), savings are made on bracing and anchoring. In strong gusts this leads to deformation, vibration, and accelerated wear of the mounting.

4. Mixing materials without considering compatibility
   Poorly thought-out combinations of steel, aluminum, and stainless steel without isolation can lead to galvanic corrosion at contact points.

5. Refusing powder coating where appearance matters
   For carports and façade solutions, only galvanized steel is used, ignoring the developer’s architectural requirements. The result is rework, on-site repainting, and commissioning delays.

6. Ignoring logistics and assembly
   Complex nodes are designed that are difficult to transport and assemble in tight conditions. It is much more efficient to plan for demountable trusses and standardized mounting rails in advance.

7. Late ordering of mounting systems
   Modules and inverters are already in stock, while metal structures are still in design. This shifts commissioning dates and increases costs due to urgency.

Accurate calculation based on a technical specification and early involvement of the mounting manufacturer help avoid these problems.

How calculation based on a technical specification works and what data is needed

For accurate calculation of PV mounting and metal structures for PV plants in Tashkent, initial data are crucial. The more complete the technical specification, the faster you will receive a working solution and commercial offer.

Minimum data set for calculation:

• type of facility: roof, carport, ground-mounted array;
• facility location (city/district, open site or built-up surroundings);
• installed capacity or number and type of modules;
• layout scheme (number of rows, orientation, tilt angle, height);
• type of base: concrete, profiled sheet, soil, sandwich panel, etc.;
• material requirements (steel, stainless steel, aluminum) and coating (galvanizing, powder coating);
• need for turnkey installation or supply of metal structures only;
• desired manufacturing and commissioning dates.

Additionally, it is useful to attach:

• roof or site plan with dimensions;
• photos of the facility and its immediate surroundings;
• developer’s architectural requirements (for carports and façade solutions).

Based on the technical specification, load calculations are performed, profile cross-sections are selected, and types of mounting rails, clamps, and connection nodes are defined. If necessary, several options can be proposed: basic, reinforced, and with enhanced corrosion protection.

Production and logistics timelines in Tashkent

Timelines depend on project size, complexity of metal structures, and production workload.

Planning takes into account:

• time for calculation and technical specification approval;
• preparation of drawings and nesting plans for laser cutting and bending;
• manufacturing of elements (cutting, bending, welding, powder coating);
• quality control of assembly nodes and packaging;
• delivery to the site in Tashkent or to the regions.

For standard solutions and medium volumes, timelines are usually shorter than for fully custom structures. However, custom manufacturing is what allows optimization of metal consumption, simplification of installation, and consideration of the specific features of a given facility.

FAQ on PV mounting for solar panels

1. Can the same type of mounting be used for roofs and ground-mounted arrays?
As a rule, no. Mounting rails and clamps can be the same, but load-bearing elements, connection nodes, and anchoring differ due to different loads and bases.

2. Which material should be chosen for mounting in an industrial zone in Tashkent?
A combined approach is often used: load-bearing metal structures made of steel with protective coating, and critical nodes and small fasteners made of stainless steel or aluminum to increase corrosion resistance.

3. Is it possible to plan for future expansion of the PV plant from the start?
Yes, during calculation based on the technical specification, you can provide additional locations for mounting rails, reinforced carport columns, or spare length of ground-mounted arrays.

4. How critical is the accuracy of the technical specification for mounting calculation?
Metal consumption, cost, and timelines directly depend on the accuracy of the technical specification. Inaccurate data on the roof or soil lead to redesign and delays.

5. Is powder coating necessary if galvanizing is already applied?
For purely technical facilities, galvanizing is sufficient. For carports, façade solutions, and facilities with design requirements, powder coating combines protection and appearance.

6. Can existing metal structures be used for a PV plant?
Sometimes yes, but verification of load-bearing capacity and connection nodes is required. Often it is simpler and more reliable to design a separate frame for the solar panels.

7. How to account for wind loads for a specific site?
In calculation based on the technical specification, facility location, site exposure, and structure height are considered. Reinforced solutions may be used for edge rows of arrays and carports.

8. What are the benefits of contract manufacturing of custom mounting systems?
It allows you to adapt metal structures to your installation standards, standardize nodes, reduce on-site assembly time, and optimize metal consumption.
