Low Investment: Compared to traditional energy generation equipment, the initial investment for photovoltaic roof mounting brackets is relatively small, making them suitable for homes and small businesses.
Energy Savings: By installing photovoltaic roof mounting brackets, you can harness solar energy to meet part or all of your electricity needs, thus reducing electricity costs.
Profit Generation: Excess energy can be fed into the grid, generating a certain income. Additionally, idle roof space can be rented out for extra revenue.
Sunshade Function: Photovoltaic roof mounting brackets provide shading, reducing indoor temperatures and lowering the need for air conditioning and other cooling systems, further saving energy.
Carbon Emission Reduction: Photovoltaic power generation is a clean energy source that does not produce pollutants or greenhouse gases, helping to reduce carbon emissions and protect the environment.
Utilization of Idle Roof Space with Rental Income: Renting out idle roof space to photovoltaic power plant developers not only generates rental income but also makes full use of available space resources.
Sun Protection with Potential Grid-Connected Income: Photovoltaic roof mounting brackets can block sunlight, reducing UV damage to the roof, while in some regions, grid-connected power generation rental income can be earned.
No Damage to Original Waterproofing and Seamless Integration with Roof: During installation, professional teams ensure that the original waterproofing structure of the building is not damaged. The brackets integrate perfectly with the roof, maintaining the aesthetic of the building.
Material Strength:
Steel: Steel has high strength, making it advantageous in large-span areas, high-wind regions, and large-scale power plants. For scenarios where structural strength is critical, steel can better withstand wind and gravity loads.
Aluminum Alloy: The strength of aluminum alloy is about 70% of that of steel. It is lightweight and suitable for small-span systems or roof-mounted power stations in corrosive environments. For roofs with strict weight restrictions, the lightness of aluminum alloy reduces pressure on the roof.
Deflection Deformation:
Deflection deformation depends on the profile shape, size, and modulus of elasticity. Under the same conditions, aluminum alloy deforms about three times more than steel. This means that when designing, you need to account for the greater deformation characteristics of aluminum alloy. For precision-sensitive applications, additional reinforcement may be required.
In practical applications, if the roof has a small span, the deflection deformation of aluminum alloy may be within acceptable limits, and its lightweight nature can ease the installation process.
Corrosion Resistance:
Steel: Steel typically relies on hot-dip galvanizing or zinc-magnesium-aluminum coating for corrosion resistance, lasting over 20 years in normal environments. For example, steel structures used in coastal environments benefit from galvanizing techniques, which ensure a certain lifespan. However, in high-humidity and high-salinity environments, regular maintenance is required. In marine or saline areas, steel's corrosion rate increases, necessitating regular checks and maintenance.
Aluminum Alloy: Aluminum alloy forms a dense oxide film through anodizing, providing excellent corrosion resistance. The oxide layer effectively prevents corrosion in atmospheric environments, and its corrosion rate decreases over time.
Cost:
The cost of aluminum alloy brackets is 1.3 to 1.5 times that of steel brackets, mainly due to the higher material and processing costs of aluminum alloy.
In small-span systems, the cost difference between the two is minimal. For small-span systems like color-coated steel roofs, aluminum alloy brackets and steel structures are similarly priced, and the lightweight nature of aluminum alloy reduces transportation and installation costs.
Zinc-Magnesium-Aluminum Brackets:
A new corrosion-resistant method, offering good quality and stable performance. Zinc-magnesium-aluminum photovoltaic brackets are easy to process, self-healing, and highly resistant to corrosion. This is an innovative anti-corrosion approach.
Produced directly by steel mills, reducing production cycles and costs. Compared to traditional hot-dip galvanized brackets, zinc-magnesium-aluminum brackets do not require additional galvanizing treatment by the bracket factory, simplifying the production process and improving efficiency.
In conclusion, selecting the appropriate roof photovoltaic mounting brackets requires considering multiple factors, including the specific needs, environmental conditions, materials, types, manufacturers, and installation and maintenance requirements. Only by choosing the right brackets can you ensure the safe and efficient operation of the photovoltaic system, providing long-term economic and environmental benefits.
