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.

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.

Are Ground-Mounted Systems Suitable for All Soil Types?

Ground mounted solar systems are popular in photovoltaic projects because they offer flexibility, scalability, and optimized panel placement. But a common question is whether they suit all soil types. The answer depends on assessing the site and choosing the proper foundation.

solar panel ground mount rack

These systems can generally be installed on various soils like sand, clay, gravel, or mixed types. The trick is picking a foundation that fits the soil’s nature. Typical options include ground screws, driven piles, and concrete bases, each working best under certain conditions.

For stable soils like compact clay or dense sand, ground screws often work well. They’re quick to install with little disruption and provide good support. By adjusting the screw size, installers can get the needed stability for the panels.

In softer or loose soils, deeper foundations or thicker ground screws might be needed to ensure solid support. Soil compaction and engineering checks help avoid future shifting. Proper design keeps the panels stable and aligned.

Rocky or hard ground makes installation tricky. Large stones or shallow bedrock can block ground screws or piles. In such cases, pre-drilling or using concrete footings may be required. Though this adds complexity and cost, it keeps the system secure.

Soil moisture and environmental factors also matter. Areas with high water tables or flooding risk need corrosion-resistant materials, like hot-dip galvanized steel, and good drainage to protect the system over time.

In cold regions, frost depth is important. Freezing and thawing can shift soil, so foundations must go below the frost line for lasting stability. This affects how deep and what type of foundation is used.

Modern mounting systems, like those from SIC Solar, offer different foundation options to fit various ground types. This flexibility helps install solar setups safely in many environments.

Before installation, geotechnical surveys and soil tests are crucial. They reveal soil makeup, strength, and risks, guiding engineers to design a safe, effective foundation.

Overall, Ground mounted solar systems are versatile but rely on matching foundations to soil conditions. With the right design and materials, they can work well across many sites.

Can Crops Grow Effectively Under Solar Panels?

As solar energy finds new uses, combining it with farming—known as agrivoltaics—has gained attention. This method places solar panels and crops on the same land. People often ask if crops can grow well under panels, and when designed right, the answer is usually yes.

agricultural solar mounting

Solar panels cast shade underneath and between rows. Too much shade hurts plants, but controlled shading can actually help some crops. Many plants don’t need full sun and can do well with diffused light. In hot areas, shade can reduce heat stress and improve crop health.

A big benefit is that panels create a better microclimate, lowering soil temperature and cutting water evaporation. This keeps soil moist longer, which helps especially where water is limited. This can mean less irrigation and water savings for farmers.

Picking the right crops is important. Shade-tolerant ones like leafy greens, herbs, and some berries often thrive under panels. Lettuce and spinach, for example, do well in the cooler, shaded spots.

System design matters too. Panel height, spacing, and angle must let enough sunlight reach the crops. Elevated mounts give space for farming tasks like planting and harvesting. Proper spacing between rows ensures sunlight shines through at different times.

New mounting systems, like those by SIC Solar, can be customized for agrivoltaics. These allow energy production and farming to coexist effectively.

This approach also helps farmers earn extra income from solar power while growing crops. Using land this way boosts productivity and can make farms more financially stable. Sometimes, panels even shield crops from harsh weather like hail or heavy rain.

But not all crops suit shading; some need intense sunlight and might yield less under panels. That's why careful planning and testing are key before starting an agrivoltaic setup.

Maintenance is another factor. Equipment needs to move between rows, and mounts must handle both weather and farm work. Good designs help solar and farming run smoothly together.

Agrivoltaic systems show solar and farming can share land successfully. With smart design, the right crops, and sturdy mounts, crops can grow well under panels while supporting clean energy.
