Proportion of aluminum consumed by solar panels and photovoltaic panels

Are aluminum panels a good choice for solar panels?

In fact, the metal accounts for more than 85% of the mineral material demand for solar PV components – from frames to panels. Aluminum extrusions are incredibly versatile, making them a perfect option for solar panel frames.

Are aluminum solar panels bad for the environment?

But the production of pure aluminum which is used in solar panel frames comes with a huge energy cost that could translate to bulk emissions. According to the International Energy Agency, solar panels are predicted to provide roughly a third of the world's total electricity demand by 2050.

Can solar panels help reduce aluminum demand?

Efficiency gains in solar yields and panel configurations could help reduce aluminum demand, but the sheer number of solar panels needed – and the urgency of the climate crisis – means we need to pull out all the stops.

Does the PV industry rely on imported aluminum materials?

First, we assume that the proportion of imported Al-containing materials used in the PV industry is equal to that of imported Al-containing materials in China. In reality, high-end aluminum materials such as aerospace aluminum alloys, automotive body sheets, and lithium-ion battery aluminum foils still rely on imports (SHE et al., 2020).

How much aluminum is used in photovoltaic systems in China?

The consumption of aluminum (both primary and recycled) for the production of photovoltaic systems accounted for 0.0007 % of China's total aluminum in 2000, and this figure increased to 3.3 % by 2020, representing an approximate 5000-fold increase from the year 2000 (Tables S5 and S8).

Why is aluminum used in photovoltaic systems?

Aluminum is widely used in the manufacture of photovoltaic (PV) systems such as BSF and PERC cells (Allen et al., 2019), inverters (Zeng et al., 2017), brackets (Lv et al., 2017), and frames (ITRPV, 2022) due to its excellent electrical conductivity and durability.
