About Development trend of steel for solar bracket
In this paper, three types of weathering steel were developed as substitutes for galvanized steel Q235. The mechanical properties and wet-dry accelerated tests were carried out for the steel. The surface morphology, composition and element distribution of the corrosion products were analyzed in detail.

Firstly, PV deployment scale and development path should be determined not only consider the economic cost and climate cost, but also the “metal requirement” constraints. For instance, faster development path increases metal demand directly, and increase secondary metal supply potential indirectly.
Results show that the associated electrical grids require large quantities of metals: 27–81 Mt of copper cumulatively, followed by 20–67 Mt of steel and 11–31 Mt of aluminum. Electrical grids built for solar PV have the largest metal demand, followed by offshore and onshore wind.

6 FAQs about [Development trend of steel for solar bracket]
What are metal demands & decommissioned outflows for solar PV projects?
Metal demands (inflows) and corresponding decommissioned metal (outflows) for each period of newly built electrical grids associated with wind and utility-scale solar PV projects toward 2050 in the SDS scenario by technology. Total demands and decommissioned outflows of electrical grids for (a) copper, (b) aluminum, and (c) steel.
Why is solar grade stainless steel so expensive?
Raw steel pricing Solar grade stainless steel is an established material for PV substrates but is expensive due to both the high quality of steel used and the extra processing required to provide a clean smooth substrate suitable for PV fabrication.
How important is trade for metal supply in China's PV sector?
Both metals have similar and high cumulative supply pressure in China’s PV sector, which highlight trade’s importance for metal supply in PV’s industry. For base metal, cumulative demand in China’s PV sector is 17.3–22.8 times in 2050 than in 2018.
What factors affect metal demand from PV developments?
Metal demand from PV developments are impacted by growth pattern, lifespan, market share, and technology improvement scenario combinations. There are also many intrinsic uncertainties in resource estimates that needs to be considered and carefully weighted when used in long-range modelling and planning.
Why is metal availability important in PV technology?
Like most other renewable energy technologies, PV technologies tend to be more metal intensive, which makes metal availability an important consideration for future large-scale deployment , , . 1.1. Review of earlier works
Do metal demands increase as renewable power capacity increases?
The results demonstrate that as the expected installed capacity of renewable power in the STEPS, SDS, and NZE scenarios increase in sequence, the metal demands for their electrical grid systems also grow accordingly.
