Full Lifecycle Energy Saving and Environmental Protection

In terms of energy saving and consumption reduction leveraging the synergy between high strength and lightweight properties

of the new alloy the Company significantly reduces unit material consumption of frame profiles and overall module weight

while meeting mechanical load wind and pressure resistance and long-term structural safety requirements. This directly lowers

energy consumption in production extrusion transportation and handling and on-site installation. It also reduces load-bearing

requirements for power plant supports improving system compatibility and installation efficiency. The material's excellent

structural stability ensures long-term module mechanical reliability reduces operation and maintenance losses and failure risks

and helps PV systems generate power efficiently and stably thereby amplifying the overall energy-saving benefits of clean

energy.In terms of environmental protection and low-carbon performance the material's long-term weather resistance salt spray

resistance acid rain resistance and resistance to heat and humidity aging enable the Company to extend the service life of

PV modules to over 25 years. This significantly reduces frame replacement frequency and resource consumption while cutting

waste generation at the source across the lifecycle. On the production side the Company adopts green and clean production

processes including chromium-free passivation low-VOC surface treatment and energy-efficient melting and extrusion

to reduce emissions of heavy metals and harmful substances and align with clean production and ecological protection

requirements. Relying on aluminum alloy's inherent properties of high recyclability and high regeneration rates combined with

a closed-loop recycling design the Company significantly reduces recycling energy consumption and the full-lifecycle carbon

footprint of retired frames. This reduces pressure to extract virgin resources and promotes the transformation of the PV industry

from linear production to a circular economy.
