How to choose the right mini rail for your metal roof solar mounting system ? It depends on the shape of the metal roof sheets. If the metal roof sheet is trapezoidal shape, then we can choose narrow version mini rail as there is a long small flat on the ridge of the sheet. This kind of mini rail can be fixed on the flat ridge of metal sheet by driving self drilling screws through the holes into the roof . EPDM pads should be under the holes in order to protect roof from water in. If use this kind of mini rails, horizontal installation is the only choice.

If the shape of roof is trapezoidal or wave shape, we can use wide version mini rail. We put mini rail spanning the ridges of metal sheet and use st6.3&25 mm self drilling screws to fix it . The EPDM should be stuck under the holes to prevent from water infiltration. If you use wide version short rail, then the panel installation direction should be vertical only.


How to Maximize Efficiency with Solar Mounting Systems

With the changing climate to clean and renewable energy, solar mounting systems are also important in extracting maximum power out of your solar panels. Although most individuals consider the panels only, the mounting system dictates the superiority of the panels as time goes by.


A good mount is one that gets the maximum sunlight on the panels, holds them secure and lasts longer - is worth more investment. The most sophisticated panels will not work effectively when mounted improperly in either design or installation.


This manual discusses the reasons why a Solar Mounting System Solutions Manufacture can assist you in realizing greater energy production, safety and long-term savings regardless of whether you are a homeowner, engineer, EPC company or solar installer.

Understanding the Role of Mounting Systems in Solar Efficiency


All solar systems require a robust base and that is what solar mounting systems offer. They have panels that are securely fixed in place be it on the roofs, on the earth or floating on the water.


A properly designed mounting system has panels at right angle to the sun and therefore it receives the maximum sunlight. It is also defended against extreme weather such as wind, rain, and snow.


Good mounts are also used to assist in ventilation below the panels and maintenance of a cooler panel, as well as enhanced power production by 5-10 percent. The construction of solar mounting systems will be of quality which will guarantee a stable performance and prolonged life.

Key Factors That Affect Solar Mounting Efficiency

Orientation and Tilt Optimization

Direction and tilt of the panels have a direct impact on generation of energy. Any tiny error in angle can cut off production. The sunlight and shadow analysis tools are tools used by professionals to locate the optimal positioning. The solar mounts which track the sun can increase energy production by 20-25 percent but are more expensive and require more maintenance.


Material Quality and Structural Integrity

Mounts are exposed to seasons of sun, wind, and rain. Aluminum mounts are non-corrosive and lightweight, which is suitable for the roof. Major ground systems which require strength and stability are provided with steel. Maintenance costs may be cut by selecting long lasting materials at this stage. Trustworthy solar mounting systems supplier companies are interested in long term performance and structural stability to secure your investment.

Ventilation and Thermal Management

The panels that are used in solar heat are heated by the sun and they lose their efficiency by every degree. Mounts, which enable passage of air underneath the panels, make them cooler and thus energy efficient, particularly when it is hot.

Installation Accuracy and Engineering Design

Accuracy in installation is important. Power may be lost or damaged by loose bolts, rails that are not straight, or improper angles of tilt. The choice of a reliable manufacturer of solar mounting systems will guarantee the correct positioning, stability, and resistance.

Maintenance Accessibility and Safety

The easy-access mounts ensure that cleaning and inspection is easy. Routine maintenance is beneficial as it makes panels work in a regular manner and minimizes the chances of down time thus making it reliable over time.

Emerging Innovations in Solar Mounting Systems

Solar technology is still developing and so is solar mounting system solution manufacture.


Modern mounts now emphasize:


  • Quick installation using pre-assembly components.
  • Enhanced safety of anti-slip or anti-rust coating.
  • Intelligent tracking with tilt-adjustment and fault-detection
  • Tilting to minimize the pressure of the wind.



The massive solar farms tend to have sophisticated tracking systems that track the sun motion, which optimizes the process and reduces shading.

Choosing the Right Mounting System for Your Project

Different types of solar mounting systems are needed in each project and therefore the choice of the right type is the key to success.


Types of Mounting System


Roof mounts: Ideal in residential and commercial rooftops. Make sure that your roof is waterproof and robust.

Advantages of Gabion for Solar Rack Installation

When discussing ground-mounted photovoltaic (PV) projects, many people first think of ground screw foundations or concrete foundation as the installation base.

However, many overlook a more economical and convenient foundation solution: gabion .

Gabion (also known as stone cage) ground-mounted PV systems use metal mesh cages filled with stones as a counterweight foundation to fix the PV supports to the ground.
This method has significant advantages in projects with special geological conditions and high environmental requirements:
1. No excavation or foundation damage required & Preserves existing terrain: Unlike traditional cast-in-place concrete pile or helical pile foundations, gabion mesh counterweights do not require large-scale excavation or damage to the soil structure, making them ideal for landfills, brownfields (contaminated land), or ecological reserves.
2. High adaptability: Can be deployed directly in rocky areas, hard ground, or areas where drilling is impossible.
3.Convenient and flexible construction & Rapid installation: Gabion mesh can be prefabricated or filled on-site, reducing the waiting time required for concrete curing and significantly shortening the construction period.
4. Mobility: If the power station needs to be relocated or the land lease expires, the gabion foundation is easy to dismantle, generating almost no construction waste.
5. Excellent Drainage and Ventilation & Performance: Prevention of Water Accumulation: The gaps between the stones have excellent permeability, unlike concrete foundations which impede rainwater penetration, effectively reducing site drainage pressure.
6. Natural Cooling: Good air circulation helps dissipate heat from the bottom of the modules, theoretically improving the power generation efficiency of photovoltaic modules in high-temperature environments.
7. Economic and Environmental Costs: Local Material Sources: If waste rock or gravel resources are available at or near the project site, material transportation costs can be significantly reduced.
8. Low Carbon Footprint: Using natural stone as ballast is more environmentally friendly than concrete, which emits large amounts of carbon dioxide during production.
9. High Stability and Durability: Wind and Slip Resistance: The large volume and weight of the gabion baskets provide excellent wind uplift resistance.
10. Structural Flexibility: Compared to rigid concrete foundations, it better adapts to minor foundation settlement or surface deformation and is less prone to cracking.

How to Choose Solar Mounting Structure in Coastal Areas?

Due to the high salt spray corrosion, strong wind loads, and high humidity of coastal environments, the requirements for solar mounting system differ significantly from those in inland areas. Therefore, the following aspects should be considered when selecting solar mounting:

anti-corrosion solar rack

1. Choosing the Suitable Material:

* Stainless Steel (e.g., 304, 316): Extremely corrosion resistant, especially 316 stainless steel, suitable for the high-salt environment of the seaside, but extremely expensive.

* Aluminum: Lightweight, corrosion resistant (with a natural oxide film protection), and easy to install. Its strength is relatively lower than steel, suitable for rooftop projects in coastal areas; ground-mounted designs need to be reinforced to withstand wind loads.

* Hot-dip Galvanized Steel: Common solution and moderately priced, the hot-dip galvanized layer provides corrosion protection for a certain period. For coastal areas, a thickness of ≥85 μm of the hot-dip galvanized is recommended.

* ZAM Coated Steel: Affordable price; compared to hot-dip galvanized steel, ZAM steel offers 2-3 times longer salt spray resistance, making it particularly suitable for the high humidity and high salt environment of the seaside.

2. Choose a suitable structural design solution

* Fixed solar ground solutions: The design should focus on multiple diagonal braces, large columns, and strong nodes. In typhoon areas, the supports should be designed according to wind pressure, and reinforcement rods or thicker profiles should be added if necessary.

* Roof solar supports: Considering the limited load-bearing capacity of the roof, especially old or lightweight roofs (such as tin roofs with corrugated steel sheets), the solar mounting solution primarily use aluminum structure and should pay attention to structural safety.

* Tracking solar solutions: PV tracking systems have poor wind resistance, posing a high risk when used in high-wind-speed coastal areas, and incurring high costs and maintenance expenses.

3. Pay attention to construction and maintenance.

*Construction requirements: Welded parts should be properly treated for corrosion protection. Bolts are best made of stainless steel or galvanized with anti-loosening measures.

*Regular maintenance: In coastal areas, it is recommended to check the bolts and anti-corrosion coating of the supports every 6-12 months and promptly treat any rust or peeling.

The key to choosing solar mounting systems in coastal areas is: corrosion-resistant materials + wind-resistant structure + regular maintenance. CORIGY is a professional solar mounting solution provider, offering the most cost-effective coastal solar support design solutions tailored to the environment. Products include solar ground-fixed structures, roof solar solutions, carport solar mounts, and other solar mounting products, with extensive experience in coastal PV support projects.


What should be noted when installing solar mounting system on a flat roof?

The application field of flat roof photovoltaic support system is wide, covering multiple fields such as residential buildings, commercial buildings, industrial plants, etc. Among them, residential buildings have become the main source of demand for flat roof photovoltaic support systems due to their huge market demand and vast market space, accounting for about 40% of the market share.

pre-assembled flat roof solar bracket kits for fast installation

Faced with numerous photovoltaic bracket solutions, the following are three aspects that need to be paid attention:

1. Avoid flat placement of solar panels: Installing modules in a flat manner can easily accumulate dust, resulting in loss of power generation, inconvenient cleaning, and difficulty in removing accumulated water. It is also difficult to remove dust through natural rainfall. It is recommended to make a certain inclination angle when laying flat, usually 5-10 degrees, while facing towards the optimal orientation.

2. Consider the issue of obstruction: The power generation efficiency of solar panels is highly dependent on direct sunlight, and if they are obstructed by trees, buildings, etc., it will seriously affect the power generation efficiency. Before installation, shadow obstructions should be eliminated. If the obstruction source cannot be removed, consideration should be given to changing the installation site.

3. Pay attention to roof structure and waterproofing issues: The weight of photovoltaic panels and solar mounting structures may put pressure on old or structurally weak roofs. The long-term load caused by installing PV brackets may lead to fatigue and potential damage to the roof structure. Some solar roof brackets require drilling holes on the roof during installation, which can damage the original waterproof layer and increase the possibility of water leakage. So before installation, it is necessary to evaluate and repair the roof structure and waterproof layer.

For the installation of flat roof solar brackets, commonly used are ballast type and concrete foundation mounting brackets type. CORIGY has more than 15 years of experience in photovoltaic bracket design and production, and can provide various professional design solutions based on the load-bearing capacity of the roof to ensure that the bracket installation is simple, firm, and efficient in generating electricity within safe wind speeds.
