Aluminum Frames and PV Module Frames: Indispensable Infrastructure for Commercial Solar PV Deployment
1. Overview of Aluminum Frames and PV Module Frames in Solar Systems
1.1 Basic Definition and Core Functions
PV module frames, universally made of industrial-grade
aluminum frames, are essential structural accessories for photovoltaic panels, serving as the protective and load-bearing skeleton of solar modules. Dominating over 95% of the global solar framing market, aluminum-based frames have completely replaced steel and plastic alternatives due to their unique comprehensive performance, becoming the standard configuration for mainstream PV modules worldwide.
For B2B players including module manufacturers, EPC contractors, and solar project developers, qualified
aluminum frames undertake three core missions. First, they enhance structural rigidity, resisting external mechanical pressure such as wind loads and snow accumulation. Second, they insulate and protect PV cells, preventing water penetration and physical damage during transportation and long-term operation. Third, they standardize module installation, enabling seamless matching with global solar mounting systems and reducing on-site construction costs.
1.2 Industrial-grade Material Standards
Commercial
PV module frames mainly adopt 6063-T5 aluminum alloy, the most mature material for solar structural parts. This alloy features high strength-to-weight ratio, excellent extrudability, and superior corrosion resistance, fully complying with international IEC 61701 salt spray resistance standards and UL mechanical load certification requirements. Most B2B customized products adopt anodization surface treatment, forming a dense protective oxide layer to adapt to harsh scenarios such as coastal, desert, and industrial photovoltaic projects, supporting the 25-year service life warranty of PV modules.
2. Global B2B Market Scale and Demand Dynamics
2.1 Market Size and Growth Data
The booming global photovoltaic installed capacity directly drives the steady growth of demand for
aluminum frames and
PV module frames. According to Wood Mackenzie’s 2025 global solar industry report, the world’s newly installed PV capacity reached 495 GW in 2024 and is expected to remain stable at 493 GW in 2025, maintaining a high-volume shipment base for solar supporting components. Industry data shows that every 1 GW of PV installed capacity consumes approximately 13,500 tons of aluminum materials, and the global demand for solar aluminum frames will reach 2.93 million tons in 2025, with continuous rigid demand from the B2B solar supply chain.
Per Future Market Insights (FMI) statistics, the global market value of solar
PV module frames will maintain a CAGR of 3.2% from 2024 to 2030. Driven by large-scale utility solar and commercial rooftop projects, the market scale is steadily expanding, bringing stable order demands for frame manufacturers, aluminum profile processors, and supporting suppliers in the B2B market.
2.2 Regional B2B Demand Distribution
The Asia-Pacific region dominates the global
aluminum frames supply and demand market, contributing over 65% of the world’s PV module frame output, with China as the core production base. Relying on complete aluminum profile processing and photovoltaic supporting industrial chains, Chinese suppliers supply most standardized and customized
PV module frames for global mainstream module manufacturers.
Europe and North America are high-quality incremental markets. Benefiting from carbon neutrality policies and clean energy subsidy plans, local commercial and industrial solar projects have raised strict requirements for frame durability and certification compliance. Different from the price-oriented demand in emerging markets, European and American B2B buyers prioritize product quality, certification completeness, and supply chain stability, driving the upgrading of high-end
aluminum frames products.
3. Core Competitive Advantages of Aluminum Frames in B2B Scenarios
3.1 Cost and Performance Balance
Compared with stainless steel and composite materials,
aluminum frames have irreplaceable B2B application advantages. Their lightweight property effectively reduces module transportation costs and roof load pressure, which is particularly critical for distributed commercial photovoltaic projects.
Meanwhile, standardized extrusion production greatly lowers mass manufacturing costs, meeting the low-profit and high-volume operation characteristics of the solar industry. For EPC enterprises and module factories, stable cost control and consistent product quality are the core reasons for long-term adoption of aluminum
PV module frames.
3.2 Environmental and Recyclable Value
In the context of global industrial carbon reduction, the 100% recyclable feature of
aluminum frames has become a key competitive point in B2B procurement. Recycled aluminum can reduce production carbon emissions by nearly 70% compared with primary aluminum, helping solar enterprises complete ESG assessment and meet the green procurement standards of international investment institutions.
At present, more than 30% of global mainstream solar frame suppliers have launched recycled aluminum frame products, which have become the preferred choice for large-scale commercial photovoltaic projects.
4. B2B Procurement Trends and Industry Future Outlook
4.1 Current Procurement Focus for Commercial Buyers
In the B2B trading market of
PV module frames, buyers’ procurement logic is gradually shifting from single price competition to comprehensive strength evaluation. Modern module manufacturers and EPCs focus on three major indicators: dimensional tolerance accuracy (controlled within ±0.5mm), environmental adaptability certification, and customized production capacity.
With the popularization of large-size 210mm wafer modules and bifacial modules, personalized frame structure designs have become a necessary service for competitive suppliers of
aluminum frames.
4.2 Future Industry Development Trends
In the next five years, the
aluminum frames and
PV module frames industry will present two major development trends. First, lightweight and high-strength upgrading: new aluminum alloy formulas will further reduce frame weight while improving wind and pressure resistance, adapting to ultra-large module applications. Second, green and low-carbon iteration: the penetration rate of recycled aluminum frames will continue to rise, becoming a rigid standard for high-end commercial photovoltaic projects.
As the global photovoltaic market maintains medium and high-speed growth, the B2B demand for high-quality, standardized, and green
PV module frames will continue to expand. As the most basic and critical structural component of solar systems,
aluminum frames will always be the core supporting link for the sustainable development of the global photovoltaic commercial market.
