Corigy not only designed many big mega watts solar mounting structures on flat ground , but also have many excellent experiences in making solar mounting solutions for mountain terrains with various slopes. How to design the photovoltaic mounting structure on slope ? Corigy have developed height adjustable ground screw, angle adjustable clamp, and angled beam to deal with different cases of sloped solar mountings. There are four types of slope solution 1/2  When on flat ground or the PV table perpendicular to the slope’ direction just as picture. We use normal type of mounting structure, no need to add any extra component. 3.  When the PV table is placed diagonally on a slope, the angle adjustable clamp and height adjustable ground screw need to be added in structure. The function of these two adjustable components is to ensure all the height from module to the slope are the same.  4.  When the PV table is placed vertically on the slope , special beam with angle will be used in such case. In this solution, the angle degrees of beam should be the same as the slope angle. So we have to confirm the slope angle in degrees and then customize the beam based on it.Of course, the height adjustable ground screw is also used in this case. What special project information should we collect in additional for slope project ? Besides the normal on flat ground project information we need to collect , we have to collect the extra project information for slope as following: 1, What is the slope angle in degrees, and what is module orientation angle ? 2, Are the solar panels installed parallel to the slope ? Do the modules and slope also form a certain angle ? 3, Is the orientation of the module consistent with the orientation of the slope. Corigy has a lot true experiences in design slope solar mounting structures. If you have this kind of project, please feel free to contact with us to get free solution.

For PV systems, power generation is undoubtedly the most critical factor, as it directly impacts the return on investment. The installation angle of solar mounts is one of the key factors influencing power output, and how to determining the optimal angle to maximize annual solar radiation is a topic worthy of discussion. The installation angle not only affects power generation efficiency but is also closely related to the stability and cost of the whole PV system. An inappropriate angle will reduce power generation efficiency and impacting investment returns: an excessively large angle increases the structural strength requirements of the support structure, and then raising costs; an excessively small angle may reduce support costs but could require more land area for solar module installation. Therefore, it is necessary to comprehensively balance factors such as power generation efficiency, stability, and cost to determine the optimal installation angle. The installation angle of solar brackets includes two angles: tilt angle (the angle between the PV module and the horizontal ground) and azimuth angle (the angle between the orientation of the PV module and due south). Both changes in tilt angle and azimuth angle will affect the power generation of power station. Geographic location is a key reference factor, and generally speaking, solar panels need to face towards the equator to fully utilize solar energy resources. Latitude also affects the optimal installation angle of solar panels. In low latitude regions, solar panels can maintain a relatively flat angle; In high latitude regions, solar panels need to be tilted appropriately to better utilize sunlight. Here are some quick empirical formulas to preliminary determine the angle: Optimal inclination angle ≈ local latitude ± 5 ° -Low latitude (<30 °): latitude - 2 ° to 5 ° -Mid latitude (30 ° -40 °): latitude ± 2 ° (seasonal equilibrium) -High latitude (>40 °): latitude+2 °~5 ° (large angle is beneficial for snow removal) -Minimalist estimation: latitude x 0.9 To accurately determine the installation angle, you need to seek the help of a professional engineering team who will use specific software for simulation calculations.

As commercial and industrial rooftop solar projects continue to grow worldwide, TPO/PVC roofing systems have become increasingly popular due to their lightweight structure, waterproof performance, and long service life. To match these roofing systems, specialized TPO/PVC solar mounting bases are designed to provide secure installation while maintaining the integrity of the waterproof layer. Modern TPO/PVC solar mounting solutions are generally divided into three main categories: 1. Flexible PV Mounting System (No-Drilling Type) 2. Medium / Mini TPO/PVC Mounting System – Rivet Nut Fixing 3. Heavy-Duty TPO/PVC Mounting System – Rivet Nut / Disc-Fastened Type These systems are suitable for single-layer, double-layer, and multi-layer flexible roofing structures. Flexible PV Mounting System (No-Drilling) The no-drilling flexible mounting base is specially designed for membrane roofs where roof waterproof integrity is a key concern. Instead of penetrating the roof, the mounting base is directly welded onto the waterproof membrane through hot-air welding technology. This solution offers several advantages: · No roof penetration, reducing leakage risk · Seamless integration with TPO/PVC waterproof membrane · High weather resistance and long-term durability · Lightweight structure suitable for flexible roofs The mounting base usually consists of a weather-resistant PVC/TPO injection-molded base combined with an aluminum structure, forming a rigid-flexible integrated system. However, no-drilling systems are generally not recommended for coastal areas or regions with extremely high wind loads, because wind uplift resistance requirements are much higher. In such projects, medium-duty or heavy-duty fixing solutions are often preferred. Medium & Heavy-Duty TPO/PVC Mounting Systems For projects requiring higher structural strength and wind resistance, medium-duty and heavy-duty systems are commonly used. These systems typically use: · 304 stainless steel mounting bases · Rivet nut fixing systems · Disc-fastened systems · Hot-air welded waterproof integration By combining mechanical fixing with waterproof membrane welding, the system achieves both excellent structural stability and waterproof reliability. Such systems are widely used in: · Industrial metal roofs · Single-ply membrane roofing systems · TMP integrated roofing systems · Lightweight steel structure roofs Typical Application Scenarios TPO/PVC solar mounting systems are suitable for various rooftop conditions, including: · Concrete roofs with fully bonded waterproof membranes · Light steel structure roofs · Integrated tile roofing systems · Industrial and commercial flat roofs The key requirement is that the roof surface must already have a waterproof membrane installed before mounting construction begins. Professional Installation Process A standard installation procedure usually includes: 1. Roof layout and positioning 2. Roof surface cleaning 3. Hot-air welding of the mounting base 4. Aluminum ...

The material of the supporting structure of a photovoltaic carport directly determines its service life, load-bearing capacity, maintenance cost and applicable scenarios. Carbon steel and aluminum alloy are the two most mainstream materials on the current market, with significant differences in performance, cost, environmental protection and other dimensions. The following is a detailed summary of their respective advantages and disadvantages to provide a reference for material selection. I. Carbon Steel Photovoltaic Carport Carbon steel photovoltaic carports mainly adopt carbon steel grades such as Q235B and Q355B as the core support materials, which are usually treated with anti-corrosion processes including hot-dip galvanizing, cold galvanizing or spraying. They are the mainstream choice for industrial areas, large parks and other scenarios, occupying about 75%-80% of the market share, with core advantages in structural strength and cost performance. Advantages High load-bearing capacity and outstanding span performance. Carbon steel features high yield strength (approximately 235MPa for Q235 and 355MPa for Q355), with tensile strength ranging from 400MPa to 550MPa, far exceeding that of aluminum alloy. A single steel column can bear a load of over 500kg, enabling a large-span design of more than 12 meters without excessive intermediate columns. It saves site space and is compatible with heavy-duty photovoltaic modules, suitable for large-area solar panel arrangement to improve power generation efficiency and land utilization rate. Some products can withstand wind speeds up to 60m/s, reaching a wind resistance grade of Level 10 to 12, and deliver strong snow load resistance, meeting the application demands of snowy regions in northern China. Low cost and superior cost performance. The raw material price of carbon steel is only 1/3 to 1/2 of that of aluminum alloy. With mature rolling, welding and other processing technologies, component costs are low in mass production. The overall cost of the support system is about $11.5–21.4 per square meter, which greatly reduces the initial investment of photovoltaic carport projects. It is especially suitable for large-scale and cost-sensitive projects, such as industrial logistics parks and desert photovoltaic carport projects. Flexible processing and high customization. Carbon steel has excellent welding performance. Special-shaped components (such as long-span beams and corner brackets) can be customized according to site requirements, adapting to complex terrain such as mountains and sloped land. It can also be flexibly matched with concrete foundations and other metal materials, delivering strong construction adaptability. Disadvantages Poor corrosion resistance and regular maintenance required. Carbon steel is prone to oxidation and rusting by nature. Even with hot-dip galvanizing (zinc coating thickness ≥ 85μm) or surface spraying treatment, rusting issues still easily occur in harsh environments ...
