Solar Panel Aluminum Frame VS Stainless steel Frames
Comparison of solar panel aluminum frames and stainless steel frames can be analyzed in detail from several angles.
The following is the comparison:
Material Characteristics
1. aluminum frame:
Advantages:
- Lightweight: aluminum alloy density is small, making the overall weight of the frame lighter, easy to install and carry.
- Corrosion resistance: Aluminum is naturally corrosion resistant and can form a protective layer of aluminum oxide in the air to resist corrosion.
- Strength: Aluminum alloy has high strength and can effectively resist external impacts.
- Conductivity: good electrical conductivity, can play a role in lightning protection in thunderstorms.
Disadvantages:
- Cost: Compared with steel, aluminum alloy has relatively high cost.
- Service life: in some environments, the service life of aluminum alloy may be shorter than steel.
2. Stainless steel frames:
Pros:
- Strength: The strength of steel is much higher than that of aluminum alloy, which can effectively resist various external impacts.
- Corrosion resistance: steel also has better corrosion resistance, which is conducive to the long-term use of photovoltaic panels.
Cost: The cost of steel is relatively low.
Disadvantages:
- Weight: The high density of steel results in a heavier overall weight of the frame, which puts some pressure on the installation structure.
- Thermal conductivity: the thermal conductivity of steel is poor, which is not conducive to the heat dissipation of photovoltaic panels.
2. Performance comparison
1. corrosion resistance: aluminum alloy frame due to the formation of natural corrosion resistance and aluminum oxide protective layer, its corrosion resistance is better than the steel frame.
2. Strength: the strength of steel frames is much higher than that of aluminum alloy frames, but the strength of aluminum alloy frames is sufficient to meet the needs in solar panel applications.
3. Weight: Aluminum frames are much lighter than steel frames, making them more suitable for applications that require reduced weight.
4. Thermal conductivity: aluminum alloy frame has good thermal conductivity, which is conducive to the heat dissipation of photovoltaic panels; while the steel frame has poor thermal conductivity.
3. Applicable scenarios
1. aluminum alloy frame: for high corrosion resistance requirements, the need to reduce the weight and cost-sensitive scenes, such as roof photovoltaic systems, seaside or humid environment of the photovoltaic power plant.
2. Stainless steel solar Frames: suitable for cost-sensitive, high strength requirements of the scene, such as large ground-based photovoltaic power stations, wind power towers and so on.
To summarize
Solar panel aluminum frame and steel frame have their own advantages and disadvantages, the choice needs to be based on specific application scenarios and needs for comprehensive consideration.
