Single Phase String Inverter Market Set to Reach USD 3.0 Billion by 2035 with 2.5% CAGR

The global single phase string inverter market is estimated at USD 2.4 billion in 2025 and projected to reach USD 3.0 billion by 2035, reflecting a CAGR of 2.5%. While this growth trajectory appears modest compared to other renewable technologies, the market demonstrates steady resilience and strong alignment with residential rooftop solar demand, government incentives, and technological innovations.

The industry experienced an early growth push in the mid-2020s, with values reaching USD 2.5 billion in 2027 and USD 2.6 billion in 2028, before stabilizing near USD 2.7–2.8 billion during the early 2030s. By 2035, the segment edges toward the USD 3.0 billion mark, supported by stable replacement demand, smart grid integration, and residential solar system expansion.

Why the Market is Growing

The rise of residential solar photovoltaics has placed single phase string inverters at the heart of distributed renewable energy. These inverters convert direct current (DC) into alternating current (AC) for household use, making them a critical enabler of clean energy adoption.

Key drivers fueling this market include:

• Government Incentives & Net Metering: Subsidies, tax credits, and net metering schemes reduce the upfront burden for homeowners.
• Residential Rooftop Expansion: Urbanization and sustainable energy preferences are driving rooftop solar installations.
• Technology Upgrades: Advances in efficiency, monitoring, and connectivity enhance value for homeowners.
• Smart Grid Compatibility: Seamless integration with evolving digital energy systems ensures long-term relevance.
