Wood Mackenzie’s ranking for the first half of 2025 shows that the top 10 leading inverter manufacturers have a global market share of 71%.
Wooden Mackenzie has published its global inverter manufacturing rankings for the first half of 2025.
The ranking puts Chinese manufacturers Huawei and Sungrow at the top of the list, with almost identical scores of 93.9 and 93.7. Germany’s SMA is in third place, followed by Austria’s Fronius in fourth place and China’s Ginlong/Solis in fifth place.
The top ten is completed by China’s GoodWe in sixth place, Japan’s TMEIC and Israel’s SolarEdge in shared seventh place, China’s Aiswei/Solplanet in ninth place and the American company Enphase in tenth place.
Wood Mackenzie evaluated 23 leading solar inverter manufacturers from seven provinces based on eight performance criteria, including environmental, social and governance (ESG) initiatives, after-sales services, research and development (R&D), supply chain stability and manufacturing experience.
According to Wood Mackenzie’s analysis, the ten largest inverter manufacturers account for 71% of the global market share. All of these companies now offer warranty extensions of 20 years or more, which Wood Mackenzie says reflects increased confidence in product longevity and a commitment to matching the operational life of solar panels.
Wood Mackenzie also found that six out of ten leading companies have an EcoVadis ranking of silver or higher, putting them in the top 15% of companies globally for sustainability. Furthermore, eight of the top ten reinvest more than 6% of sales in R&D efforts.
Timothy Shen, senior research analyst at Wood Mackenzie, noted that competitive advantage is now determined not only by shipping volume, but also by quality of service and stable supply chains. He added that the strongest performers also use regionalized assembly strategies.
“This strategic positioning allows manufacturers to meet local content requirements and bypass import barriers while maintaining supply reliability,” Shen explains.
Each of the top 10 companies is also certified by Wood Mackenzie as a Class A inverter manufacturer. The A distinction is intended as a market signal to highlight suppliers that combine operational robustness with practices aligned with global purchasing standards. To qualify, companies had to meet at least five benchmarks defined by Wood Mackenzie.
Another five solar inverter manufacturers have also received Class A accreditation: China’s Hoymiles, Kstar, Sofar and Chint Power Systems, as well as Spain’s Ingeteam.
Wood Mackenzie’s ranking in the first half of the solar inverter rankings follows the recently published rankings of global solar panel manufacturersputting JA Solar and Trina Solar at the top of the list.
In December, the consultancy predicted that global demand for solar inverters would rise contracts in 2025 and 2026driven by market uncertainty in China, Europe and the United States.
