The global solar energy sector is seeing significant growth in specialized infrastructure markets. The solar step-up transformer market is projected to expand from an estimated $1.743 billion in 2026 to $2.711 billion by 2032, driven by the construction of solar power plants and the integration of battery energy storage systems. This growth is supported by technological shifts toward integrated solutions featuring remote monitoring and protection modules.

Simultaneously, the utility-scale solar repowering market is expected to experience rapid expansion. While previous estimates suggested a rise to $14 billion by 2035, newer market research indicates a much larger trajectory, projecting the market to reach $140 billion by 2035. This represents a compound annual growth rate (CAGR) of 21.6 percent. This trend is fueled by the need to upgrade aging solar infrastructure installed in the early 2010s, specifically targeting solar panels, inverters, and tracking systems to combat component degradation and improve efficiency.

Europe currently leads this repowering market, with significant demand in Germany, Spain, and Italy, while North America remains a major growth region.
