Install PV modules on the roof or in the ground; It is the whole of the carrier construction and connection elements that securely fix it under wind, snow and seismic loads.
In the fixed system, the angle is fixed. Single-axis tracking systems increase production by tracking the sun throughout the day. Wind stow strategy and maintenance plan are critical in monitoring systems.
Yield; depends on shading, slope, floor/roof capacity and targeted production profile. Correct static design and appropriate system selection are decisive.
Yes. To maximize rear face gain, ground clearance, row spacing and position of shading elements at the rear are taken into account.
Preliminary/final static project, manufacturing drawings, material lists, FEA/CFD analysis outputs, quality certificates and assembly instructions are delivered.
Profile/coating selection is affected by galvanizing/coating capacity, site access, ground type, weather conditions and equipment-labor plan.
A typical 25 year structural warranty is provided depending on the project and finish. Warranty conditions apply subject to compliance with the installation/operating instructions.
In our country, the design is primarily made according to standards such as TS 498, TBDY 2018, Eurocode 1-3, Eurocode 1-4. ASCE or other country standards can also be integrated upon request.
It is calculated according to local standards and climate data. Critical points can be verified with CFD.
In Türkiye projects, TBDY 2018 is taken as basis. Anchorage, foundation type and stiffness checks are made.
In many distribution regions, static projects go through authorized university approval processes.
It numerically evaluates stress/strain, buckling and local connection effects in sections.
It provides design optimization in wind suction areas by revealing the flow field and local pressure distributions.
Required for factory production control (FPC) and traceability of bearing steel/aluminum components.
Lot tracking is done with thermal samples and EN 10204 (3.1 etc.) certificates.
Eurocode partial safety coefficients and local regulations are used. It is reflected in the design according to field conditions.
Driven piles, rock anchors and concrete foundations can be used. The foundation type is selected based on the soil survey and tensile test.
Column bearing capacity and retention are verified in the field. The results are spread across the field with a heat map.
It depends on the system geometry. Many terrain systems have standard solutions for slopes up to ±15° East-West. Higher slopes are specially designed upon request.
The decision is made based on space usage, cabling cost and targeted production amount.
Yes. In aggressive soils, ZM (Zn-Mg) or HDG thickness and coating class are important.
Single column systems; It is advantageous in areas with high slopes and in areas that require cost-effective and fast installation, and the installation process is simpler and faster. Double column systems, on the other hand, are a safer option in terms of structural rigidity, load distribution and long life in high wind loads and earthquake areas.
Attention must be paid to material (EN 10204), production (EN 1090) and quality (ISO 9001) documentation.
Cable routes integrated into the rails and potential equalization accessories can be used.
The panel bottom clearance is increased and the cable route is increased. Drainage plan and stow procedures are prepared.
Trapezoidal/sandwich, standing seam, flat concrete/membrane, tile etc. Special systems are available for
No. Installation is done by compression/clamping on the seam without disrupting the seal.
It is selected according to wind suction and allowable roof load; Ballasted solutions can be applied without drilling.
EPDM seals and chemical anchors on pierced roofs; In systems without drilling, separator pads compatible with the membrane are used.
Service corridors and access roads are separated in the project; local regulations are observed.
If the purlin/carrier capacity is insufficient, reinforcement or lightweight system alternatives are evaluated.
Hot dip galvanized according to EN ISO 1461; Provides thick and durable coating on manufactured steel parts.
It is the basic standard for continuous line galvanized (pre-galvanized) steels and ZM (Zn-Mg-Al) coatings.
It offers higher corrosion resistance and a self-healing effect on section edges than standard galvanization (depending on conditions).
Expert opinion should be obtained, taking into account corrosion class (ISO 9223), pH/chemical effect and water accumulation.
Common on lightweight/corrosion resistant parts such as rails and clamps.
Magnetic coating thickness gauge and sample tests; Acceptance criteria are made according to the relevant standard.
Local repair with zinc spray/paints; It is applied in accordance with the additional provisions of EN ISO 1461.
According to ISO 3506, it is a minimum tensile strength class of 700 MPa for 304 quality stainless fasteners.
Thin film water-based zinc flake coating; It offers the advantage of high corrosion resistance and reducing the risk of joint embrittlement.
Separating washers, suitable coating combinations and water-repellent detail design are used between different metals.
No; Depending on the clamp/connection type, the manufacturer's instructions are taken as basis and the friction coefficient is taken into account.
It is important for connection torque, especially in black/top-coat coatings; affects the risk of loosening.
If stainless steel (cathodic) and zinc (anodic) come into contact together and in the presence of moisture/electrolyte, the zinc coating is consumed rapidly, coating life and connection security decrease.
Depending on the load and environmental impact, 8.8/10.9 carbon steel or A2/A4 stainless grades are preferred.
Locking nut/chemical lock, torque control plan and periodic checks are applied.
Yes; The clamp and gasket geometry are selected according to the glass-glass or glass-film module type.
Clamp spacing and clamping height are adjusted according to the module manufacturer's data.
Movement is controlled with expansion allowance and sliding holes in aluminum rails.
The clamping areas recommended by the manufacturer for cell fragility and glass edge stresses are observed.
Rear gain is preserved by minimizing shadows of cable route and construction profiles.
Excessive torque increases the risk of micro-cracks; The torque range specified by the manufacturer is observed.
Office/warehouse space, security and access, temporary power/water, stock and quality control arrangement.
Driving machine, excavation-filling equipment, lifting vehicles and special mounting apparatus.
Excavation/fill amounts and roads are optimized with 3D terrain modeling; unnecessary excavation is prevented.
Yes; Daily assembly, shipment tracking, field assembly issues and quality records are critical for management and traceability.
Kit packaging according to profile lengths and assembly order; Reduces search/transport times in the field.
Training of the teams is planned with installation manuals and field supervisors.
Installation intervals and lifting plans according to wind speed; Precautions are defined in rainfall/flood scenarios.
Coating thickness, torque control, perpendicularity/direction tolerances and visual inspection lists.
Torque/relaxation control, corrosion observation, panel mechanical control, land and foundation checks are performed.
Local repair (zinc spray/paint) or part replacement; Recurrence is prevented with root cause analysis.
It depends on correct installation, compliance with operating/environmental limits and periodic maintenance records.
More frequent inspection and preventive maintenance is required for heavy snow or chemicals such as ammonia/chloride.
It is determined by vehicle height and maneuvering area; Column spacing and vehicle entry-exit heights are important.
Gutter/downhill systems and cable routes are separated; Water accumulation is prevented.
Crash barriers/column protections and lighting plans are made.
Row spacing and elevation are determined according to the plant type; maintenance equipment transitions are planned.
HDG, ZM coatings and stainless connections are preferred for ammonia effect, but expert opinion should be taken for the coating type and thickness.
Wind/snow/seismic loads are designed by taking into account the open area frame effects.
On flat roofs, the weight (ballast) method can be applied without drilling; The bearing capacity of the roof should be verified.
