Solar Inverter Market Faces Unprecedented Downturn
The global solar inverter market is set for a significant contraction, declining for two consecutive years in 2025 and 2026. Consultancy group Wood Mackenzie forecasts a 2 per cent decrease in shipments to 577 gigawatts AC (GWac) in 2025, followed by a further 9 per cent decline to 523 GWac in 2026. This sharp reversal follows a period of record shipments in 2024.
The downturn is primarily attributed to increasing uncertainty across key global markets, including China, Europe, and the United States. Solar inverters are vital components that convert the direct current (DC) generated by solar panels into alternating current (AC) usable for power grids and homes. Their market performance is a direct indicator of broader solar energy sector health.
Navigating Evolving Market Dynamics
Joe Shangraw, a research analyst at Wood Mackenzie, stated that the solar inverter industry is entering a phase of strategic realignment. Manufacturers must adapt to evolving market conditions and regulatory frameworks after years of exponential growth.
He emphasized that continuous shipment expansion is no longer a realistic expectation, even for leading global manufacturers. Vendors will need to pivot towards new demand drivers to maintain competitiveness. These include the growing integration of hybrid solar-plus-storage systems, opportunities in retrofitting and repowering existing solar installations, enhanced cybersecurity features, the adoption of 2,000-volt architectures, and the provision of grid services.
Regional Market Outlooks
China's solar inverter market is projected to shrink by 5 per cent in 2025, reaching 304 GWac. This marks the first contraction for China since 2019. Despite this near-term uncertainty, linked to the transition between the country's 14th and 15th five-year plans, China is expected to maintain its dominant position, with cumulative demand projected to exceed 2.9 terawatts AC (TWac) through 2034.
In contrast, Asia-Pacific markets outside of China are anticipated to see growth, reaching 89 GWac in 2025. This expansion is bolstered by significant investments in domestic manufacturing and the booming rooftop solar segments in India and Southeast Asia.
Europe is bracing for a sustained decline in inverter shipments, expected to fall from 88 GWac to 83 GWac in 2025 and further below 75 GWac annually by 2032. Persistent inventory challenges and lower capture prices for utility-scale projects in markets like Spain are key drivers.
The United States market faces volatility, with shipments forecast at 47 GWac in 2025. A significant 22 per cent drop is anticipated in 2026 as tax credits under the Inflation Reduction Act begin to phase out.
Price Pressures and Cybersecurity Concerns
Inverter prices are experiencing a broad decline across all product categories, largely fueled by intense competition from Chinese manufacturers and ongoing technological advancements. Module-level power electronics (MLPE), such as optimizers and microinverters, show significant regional price disparities, with US prices being over 50 per cent higher than global averages.
Hybrid inverter prices saw a 13 per cent decrease in 2024 as DC-coupled, battery-ready systems became standard. Utility-scale inverters are facing the steepest price drops. Chinese domestic string inverter prices are expected to fall below $0.02 per watt AC. This aggressive pricing is driven by competition among leading Chinese suppliers like Huawei and Sungrow, a shift towards larger unit sizes, and falling costs of silicon carbide semiconductors.
Governments in Europe and the US are increasingly concerned about cybersecurity risks associated with remote-access capabilities of inverters. Stricter regulations are anticipated from 2026. These concerns could reshape the competitive landscape, potentially creating barriers for foreign manufacturers in Europe and leading to calls for restricting Chinese inverter imports in the US.
Long-Term Recovery Expected
Despite the current market contraction, Wood Mackenzie forecasts a recovery in the solar inverter market, surpassing its 2024 levels by the early 2030s. Key drivers for this long-term growth include increasing electrification, AI-driven demand, and a cyclical repowering market. Companies that successfully navigate current challenges while investing in next-generation technologies are poised for stronger performance as the market rebounds later this decade.
