Pitched Roof PV Mounting System Manufacturers

From design to maintenance: Pitched roof PV mounting full life cycle management

System composition of pitched roof PV mounting
The pitched roof PV mounting is usually composed of rails, connectors, component blocks and fixed bases. Compared with the flat roof system, the pitched roof mounting needs to be directly connected to the roof structure (such as tiles, color steel tiles, cement boards, etc.). Its main function is to stabilize the components and bear the loads generated by the external environment (such as wind force, snow pressure, etc.).
Taizhou Dongsheng New Energy Technology Co., Ltd. has designed a variety of applicable structural solutions based on different roof types, such as color steel tile clamp system, cement tile puncture anchor system, glazed tile hook system, etc., to achieve good adaptation with the building structure and ensure long-term safe and stable operation.

Installation method and roof type matching strategy
Different pitched roof materials and structures have different requirements for the fixing method of the mounting system. Common roof types and matching methods are as follows:
*Color steel tile roof
Color steel tiles are a common roof form for industrial plants. They have moderate strength and are easy to construct. The mounting is often fixed by aluminum alloy rails and color steel tile clamps, without penetrating the roof panel, reducing the risk of water seepage. Taizhou Dongsheng New Energy Technology Co., Ltd.'s standardized fixture structure can adapt to a variety of corrugated and trapezoidal colored steel tiles, which is convenient for quick installation on site.
* Cement tile roof
Cement tile roofs are more common in residential buildings. The mounting is usually fixed by expansion bolts or self-tapping screws in the structural beam under the tile, and is equipped with waterproof treatment technology, such as butyl rubber gaskets, waterproof caps, etc. The hook products designed by the company can flexibly adjust the height to adapt to the problem of different thickness of tiles.
* Glazed tile roof
Glazed tile roofs are highly decorative and difficult to install. Taizhou Dongsheng New Energy Technology Co., Ltd. uses a U-shaped hook method that does not damage the tile surface to connect the mounting to the wooden or concrete base structure, and connects it to the guide rail through a windproof hook to take into account both stable installation and beautiful roofing.

Material selection and structural stability considerations
The pitched roof mounting has high requirements for material strength, durability and weight. Due to certain load-bearing limitations on the roof structure, lightweight and strength balance become the design focus.
*Aluminum alloy material: 6063-T5 aluminum profiles are used in most residential and color steel roof systems. They have a good strength-to-weight ratio and are anodized to improve weather resistance.
*Stainless steel parts: All parts that are in fixed contact with the roof (such as bolts and hooks) are made of 304 stainless steel to improve corrosion resistance and extend service life.
*Structural load analysis: The design team calculates regional wind pressure and snow pressure through building load specifications, and combines factors such as pitched, orientation, and roofing materials to conduct mechanical analysis and structural reinforcement to ensure the stability of the overall system.

Angle and orientation optimization in mounting design
The pitchedd roof has a fixed pitched when it is designed, so the installation angle of the photovoltaic module is directly affected by the pitched of the roof. The appropriate inclination angle and orientation in different regions have a significant impact on the utilization rate of light:
*South-facing roof: It is most suitable for direct installation of components. If the roof inclination angle is within the range of 15°-30°, it can basically meet the sunshine requirements of most areas.
*East-west roof: Double-sided components or flat paving solutions can be used to improve the overall power generation efficiency through optimized layout.
*Special-shaped roofs: such as multi-pitched and different-pitched roofs, Taizhou Dongsheng New Energy Technology Co., Ltd. adopts a zoning layout strategy and independently designs mounting solutions for each pitched to ensure the overall performance of the system is maximized.

Waterproofing and roof protection measures
The installation process of the pitched roof mounting involves direct contact with the roof, and it is necessary to ensure that the integrity of the waterproof layer is not damaged. Taizhou Dongsheng New Energy Technology Co., Ltd. provides corresponding waterproof solutions according to different roof structures:
*Double-layer sealing pads and waterproof caps are used in penetrating fixation to prevent rainwater penetration.
*In the non-penetrating solution, a clamping structure is used, combined with rubber gaskets to reduce the pressure on tiles and metal plates.
*All products are subjected to salt spray testing and on-site rain simulation before leaving the factory to ensure the sealing effect of long-term outdoor use.

Construction process and safety management
pitched roof construction is more challenging than flat roofs, including problems such as high-altitude operations, safety protection and limited operating space. Taizhou Dongsheng New Energy Technology Co., Ltd. takes the following measures to ensure smooth construction during project implementation:
* Pre-construction assessment: Conduct on-site surveys of roof structure, pitched, and tile stability to confirm feasibility.
* Standardized process: Develop unified construction drawings and operation guidelines to avoid component dislocation or mounting loosening due to human error.
* Safety management: All installers must be equipped with safety belts and helmets and receive training for high-altitude operations.

Operation and maintenance management and system durability
As the basic support structure of photovoltaic components, the reliability of the mounting system directly affects the subsequent operation. Taizhou Dongsheng New Energy Technology Co., Ltd. provides customers with systematic operation and maintenance services, including regular inspections, bolt tightness inspections, anti-corrosion inspections, etc.:
* Timely adjustments or reinforcements can be made for problems such as component sinking and mounting loosening.
* By establishing a system archive, record the data of the entire process of construction, acceptance, and operation and maintenance, which is convenient for future traceability and maintenance.
* Provide suggestions for replacement and upgrade of accessories to extend the operating life of the system.

Pitched roof PV mounting solutions for different roof types

Definition and classification of pitched roof PV mountings
The pitched roof PV mounting is a structural system used to fix photovoltaic modules on the pitched roof. According to the different roof structures, it can be mainly divided into the following categories:
* Color steel tile roof mounting system
* Cement tile/ceramic tile roof mounting system
* Glazed tile roof mounting system
* Concrete pouring pitched roof mounting system
Different types of roofs have different requirements for structural adaptation, waterproof performance, load design, etc., so it is necessary to formulate solutions according to local conditions.

Installation characteristics and technical challenges
High-altitude operations and construction space limitations
pitched roof construction needs to consider safety protection, limited working space, and difficult operation. The mounting design should be as modular and lightweight as possible, easy to install quickly, and reduce on-site processing.
* Roof structure bearing requirements
pitched roofs generally have certain load-bearing restrictions, so the mounting system must meet the lightweight requirements and reduce the roof load while ensuring structural strength.
* High waterproofing requirements
mounting installation often involves penetrating the roof, which conflicts significantly with the traditional waterproof layer. How to ensure that the original waterproof layer is not damaged while fixing is one of the key points in the design of pitched roof mountings.
*Material selection and structural design points
Taizhou Dongsheng New Energy Technology Co., Ltd. mainly uses the following material systems:
*Aluminum alloy rails and support components
With the characteristics of light weight, strong corrosion resistance, and easy installation, it is suitable for most types of sloping roofs, especially residential buildings.
*304 stainless steel bolts and hooks
The components directly connected to the roof are mostly made of stainless steel, which improves long-term durability and corrosion resistance and adapts to various climate environments.
*Butyl rubber sealing materials and waterproof gaskets
Used for sealing when penetrating the roof, assist in maintaining the original waterproof performance of the roof and reduce the risk of leakage.

Installation strategies matching different roof structures
*Colored steel tile roof
Fixed to the purlin with metal clamps or self-tapping screws without penetrating the roof panel. The mounting structure is customized according to the roof wave type, and the installation efficiency is high.
*Cement tile/ceramic tile roof
It is necessary to set a metal hook under the tile and connect it to the roof truss structure. The tiles need to be partially disassembled during the installation process, and higher requirements are placed on the integrity of the roof during construction.
*Glazed tile roof
The installation is difficult, and it is generally not recommended to penetrate the tile surface. Use a hanging hook structure to connect the mounting without damaging the tile.
*Concrete cast sloping roof
The structure has high strength and can be directly anchored with expansion bolts. Combined with waterproof caps and sealing materials to handle the perforation position to ensure waterproof performance.

Optimization considerations of mounting inclination and orientation
The sloping roof itself has an inclination design, and the mounting needs to adjust the component arrangement according to the roof pitched:
*South-facing roof: directly install photovoltaic panels along the pitched, and use the existing pitched to improve power generation efficiency.
*East-west roof: consider using double pitched layout or double-sided components to improve light utilization.
*Irregular orientation: The company can provide customized design and adjust the angle according to the actual position to compensate for the insufficient inclination of the component.
Taizhou Dongsheng New Energy Technology Co., Ltd. introduced architectural lighting simulation tools in system design to assist in optimizing the mounting arrangement and orientation combination to improve the power generation efficiency throughout the year.

Project implementation process and technical support
The sloping roof photovoltaic system needs to comprehensively consider the building characteristics and site conditions from design to construction. The company usually implements the project in the following steps:
* On-site measurement and roof survey
Through drone mapping or manual measurement, key data such as pitched, orientation, and purlin spacing are mastered.
* Structural calculation and scheme design
Structural force analysis is performed based on parameters such as local wind pressure, snow load, and roof structure strength.
* mounting selection and drawing output
Match mounting components and output standardized construction drawings and material lists to support customers or installers to carry out efficient construction.

Installation guidance and remote technical support
Provide construction guidance videos, remote technical training or on-site technical guidance to help customers complete installation according to standards.
* Post-inspection and maintenance recommendations
Establish a project database and regularly recommend basic maintenance work such as screw tightening, connection point inspection, and anti-corrosion layer inspection.

System maintenance and operation guarantee
The maintenance of pitched roof mountings is more difficult, so the early design and material selection are particularly critical. The company recommends that customers regularly check the following items:
*Whether the connection points are loose or rusted;
*Whether the waterproof layer at the roof penetration is aged or damaged;
*Whether the mounting surface is obviously deformed or damaged by force;
*Whether the arrangement of components is offset or slipped.
By establishing operation and maintenance files and inspection plans, customers can effectively extend the system life cycle and ensure stable power generation efficiency.
