How galvalume steel supports increased energy yield in solar power installations?

Solar power installations rely on robust materials to ensure efficiency, longevity, and optimal energy generation. Galvalume steel, with its unique properties, plays a vital role in supporting the structural and performance needs of solar infrastructure. Its superior thermal and reflective characteristics, corrosion resistance, and structural integrity contribute to enhanced energy yield and durability in solar installations. 

Key properties of galvalume steel for solar power applications 

Galvalume steel is coated with a mixture of 55% aluminium, 43.4% zinc, and 1.6% silicon. This composition provides distinct advantages for solar power installations: 

1. Thermal reflectivity: the aluminium in galvalume steel increases its ability to reflect solar heat, helping reduce overheating of components and ensuring consistent energy production in high-temperature environments.
2. Corrosion resistance: the zinc-aluminium coating protects against rust, making it ideal for outdoor installations exposed to moisture, humidity, and varying weather conditions.
3. Structural strength: galvalume steel offers excellent strength-to-weight ratio, supporting solar panels without excessive structural load.
4. Durability: the material’s resistance to oxidation and wear extends the lifespan of solar panel mounts and frames. 

Benefits for energy yield in solar installations 

1. Enhanced panel performance: 

Galvalume steel minimises thermal expansion and contraction, maintaining the alignment of solar panels for maximum sunlight capture. 

Its reflective surface reduces heat absorption, protecting sensitive photovoltaic (PV) modules from thermal degradation. 

1. Optimal positioning: 

The lightweight nature of galvalume steel simplifies the design and installation of tilt mechanisms, ensuring panels are correctly positioned for maximum energy absorption. 

1. Reduced maintenance costs: 

Corrosion resistance ensures long-term reliability, minimising the need for frequent repairs or replacements, which can disrupt energy generation. 

1. Sustainability: 

Galvalume steel is recyclable, aligning with the eco-friendly principles of solar power generation. 

Applications of galvalume steel in solar infrastructure 

Mounting structures: 

Galvalume steel is widely used in fixed-tilt and tracking systems that hold solar panels in place. 

Roofing and cladding: 

Its reflective properties and durability make galvalume steel suitable for solar-integrated roofing systems, enhancing the efficiency of building-integrated photovoltaics (BIPV). 

Support frames: 

The strength and formability of galvalume steel make it an excellent choice for fabricating frames that house PV modules. 

Case studies and practical insights 

• Desert solar farms: galvalume steel is often chosen for installations in arid regions due to its ability to resist corrosion caused by high salinity and heat. 

• Urban solar roofs: galvalume steel roofing improves energy capture for BIPV systems by providing a reflective base that enhances module efficiency.
