Sungrow, Solis & GoodWe Feature Among Top 10 Solar Inverter Brands In Wood Mackenzie's Report

Huawei and Sungrow emerged as the world’s leading solar inverter manufacturers in the first half of 2025, according to the Global Solar Inverter Manufacturer Rankings H1 2025 report published by Wood Mackenzie.

Huawei secured the top position with a score of 93.9, closely followed by Sungrow with 93.7. Together with other leading suppliers, the top 10 manufacturers accounted for 71% of global solar inverter market share during the period.

The rankings assessed 23 leading manufacturers from seven countries across eight performance criteria, representing around 90% of global inverter shipment volumes in 2024.

“The 2025 global inverter landscape is led by a diverse group of power-electronics leaders that combine scale with innovation,” said Timothy Shen, senior research analyst at Wood Mackenzie. “Competitive advantage is increasingly defined not just by shipment volumes, but by strength across environmental, social and governance initiatives, service quality, and supply-chain stability.”

ESG and service capabilities gain prominence

A key finding of the H1 2025 rankings is the growing maturity of ESG practices among leading inverter suppliers. Six of the top 10 manufacturers achieved a Silver or higher rating from EcoVadis, placing them among the top 15% of companies globally in terms of sustainability performance.

In addition, all top 10 manufacturers now offer warranty extensions of 20 years or more. According to Wood Mackenzie, this reflects greater confidence in product durability and a growing effort to align inverter lifespans with those of solar modules, thereby reducing long-term risks for developers and asset owners.

Despite sustained pricing pressure across the sector, innovation remains a key differentiator. Eight of the top 10 manufacturers reinvest more than 6% of their revenue into research and development, supporting advances in digitalisation, power-conversion technologies, faster product refresh cycles and expanding patent portfolios.

Manufacturing footprints diversify to manage trade risks

Global trade uncertainties are also reshaping manufacturing strategies. Four of the top 10 solar inverter manufacturers now operate globally diversified production footprints, with facilities across China, Europe, India, the United States, Southeast Asia and Israel.

“The strongest performers are those leveraging regionalised assembly strategies,” Shen said. “This allows manufacturers to comply with local content requirements, navigate import barriers and maintain supply reliability.”

Market concentration and ‘Grade A’ recognition

Wood Mackenzie also awarded ‘Grade A’ status to inverter manufacturers that met its benchmarks for industry best practice. To qualify, companies must meet at least five of the defined performance benchmarks, demonstrating consistent and verifiable strength across key operational and financial criteria.

The Grade A designation is intended to serve as a market signal for developers, EPCs and asset owners, highlighting suppliers that combine operational robustness with strong ESG and CSR practices, sustained R&D investment and effective capacity utilisation.

Methodology

Wood Mackenzie’s inverter manufacturer rankings assess vendors across eight weighted criteria: ESG and CSR (30%), after-sales service (15%), R&D investment (15%), supply-chain stability (15%), capacity utilisation (10%), certifications (5%), financial condition (5%) and manufacturing experience (5%). The rankings are published biannually and draw on vendor surveys, public disclosures, proprietary databases and extensive industry engagement.

Where the score difference between manufacturers is 0.2 points or lower, companies are assigned the same rank.

Note: Wood Mackenzie’s inverter manufacturer rankings report does not analyse all inverter brands available in the market. It assesses 23 leading manufacturers from seven countries, selected on the basis that they collectively accounted for around 90% of global inverter shipment volumes in 2024.
