The solar energy industry has entered a high-growth phase, with global installed capacity reaching new milestones. In 2023, 447 GW of new solar capacity was added, marking an 87% increase year-on-year. Emerging markets in India, Africa, and Latin America are driving this growth alongside traditional leaders like China. Steel plays a critical role in supporting this expansion, forming the backbone of solar infrastructure and auxiliary systems.
Emerging Markets: Where Is Solar Energy Expanding Next?

In addition to China, the United States and India are the largest solar markets, Germany and Spain are fast growth markets, and Saudi Arabia is expected to have the highest growth rate in the next five years. Emerging markets like Brazil, South Africa, the Middle East, and Southeast Asia are driving solar demand through supportive policies. India is advancing rapidly, with government initiatives expected to boost demand by 25% to 40% in 2025. Saudi Arabia and South Africa are investing in large-scale solar projects, while Brazil leads Latin America, doubling its capacity to 10.9 GW in 2022 with favorable policies.
Steel Applications in Solar Energy
Ground-Mounted Solar Systems
Centralized Systems: Ground-mounted solar PV racking systems typically employ galvanized steel and ZAM steel for components including posts, diagonal braces, inclined beams, cross beams, and connectors. Hollow sections are commonly used to fabricate these structural elements. Foundations for pile-supported posts often consist of galvanized helical piles or reinforced concrete piers.
Rooftop Systems: Industrial and residential installations use lightweight, high-strength steel to reduce load without sacrificing durability.

Auxiliary Components in PV Power Station
Inverters: Enclosures are crafted from galvanized or color-coated steel to protect against environmental wear and tear.
Energy Storage Cabinets: Galvanized steel is used for storage systems that ensure grid stability and continuous power output.
Transformers and Substations: Transformers utilize silicon steel for cores, while galvanized steel is used for structural support. Substation foundations often incorporate reinforced concrete with steel reinforcements for durability.
