Let's cut through the noise – when we talk about photovoltaic panel frames, we're essentially debating between two heavyweight contenders: extruded aluminum alloys and galvanized steel. As of February 2025, aluminum frames dominate residential installations with prices ranging ¥7.25-¥42.5 per linear meter, while industrial-scale steel structures hover around ¥0.20-¥0.30 per watt. But here's the kicker: a solar farm in Inner Mongolia recently saved 18% on framing costs using hybrid aluminum-steel configurations, proving there's no one-size-fits-all solutio

But here's the kicker: a solar farm in Inner Mongolia recently saved 18% on framing costs using hybrid aluminum-steel configurations, proving there's no one-size-fits-all solution.
Component prices aren't the only numbers in freefall. Framing costs have dropped 22% since 2023 due to:
Don't fall for the "frame-only" pricing trap. A recent Zhejiang project revealed:
| Component | % of Total Framing Cost |
|---|---|
| Primary Structure | 42% |
| Mounting Hardware | 29% |
| Anti-corrosion Treatment | 18% |
| Transportation | 11% |
The recent China Datang 22.5GW framework tender exposed three critical trends:
Meanwhile, coastal projects face a 15-20% "salt tax" for marine-grade coatings. A Guangdong installer shared: "We're using sacrificial anode systems that cut replacement costs by 40%, but upfront framing costs jump 18%."
As TOPCon modules hit 0.62-0.76元/W, framing systems are adapting:
Smart buyers are now demanding:
One Jiangsu manufacturer's "framing-as-service" model – where they retain ownership and charge per kWh produced – is shaking up financing models. Early adopters report 31% lower CAPEX but face 19-year maintenance commitments.
