The global solar module manufacturing landscape is entering a period of consolidation and strategic realignment, as revealed in Wood Mackenzie’s Global Solar Module Manufacturer Ranking for the first half of 2025. The report highlights a market defined by extreme volatility and widening gaps between the industry leaders and the rest of the field, where operational efficiency and bankability have become the key measures of success, surpassing simple shipment volumes.
At the top of the ranking, JA Solar and Trina Solar emerged as joint leaders, reflecting a near-dead heat in the global solar market. Wood Mackenzie’s assessment, which evaluated 38 crystalline-silicon module manufacturers across ten core dimensions, placed JA Solar at a score of 91.7, closely followed by Trina Solar at 91.6. Trina Solar’s strong position is credited to its substantial investment in research and development, which exceeded six percent of its revenue in the first three quarters of 2025, as well as its leadership in N-type TOPCon technology. JA Solar, on the other hand, demonstrated robust vertical integration and supply chain resilience, qualities that have become increasingly important amid fluctuating global trade barriers. Rounding out the top five were Canadian Solar with a score of 90.4, JinkoSolar at 88.8, and LONGi at 87.0.
A notable feature of this year’s is the introduction of the “Grade A” classification, which signals commercial discipline and bankability to project financiers and procurement teams. This designation requires manufacturers to meet strict standards in areas such as financial stability, ESG (Environmental, Social, and Governance) performance, and reliability certifications from third parties like Kiwa PVEL or RETC. Yana Hryshko, Head of Global Solar Supply Chain at Wood Mackenzie, explained that the Grade A label identifies suppliers as low-risk, high-reliability partners. Out of all the manufacturers surveyed, 29 across nine countries achieved this distinction in the first half of 2025, reflecting the growing importance of trust and stability in procurement decisions.
Despite the strong performances of leading manufacturers, the report also highlights financial pressures in the industry. Even with record shipments, the top 10 manufacturers reported a combined net loss of $2.2 billion in H1 2025, primarily due to falling module prices. However, a clear divide has emerged between leading companies and smaller players. The top 10 manufacturers maintained an average utilization rate of 70 percent, compared with roughly 43 percent for the rest of the industry. Some companies, including Adani Solar and DMEGC Solar, even achieved full utilization at 100 percent. Geographic strategy also played a role, as non-Chinese manufacturers in the top 10 remained largely profitable by focusing on premium, protected markets in the U.S. and Europe, while Chinese manufacturers faced oversupply and domestic price competition.
Technological evolution is another key trend highlighted in the report. The industry is rapidly moving toward advanced technologies such as TOPCon 3.0 and back-contact modules, which are expected to raise mainstream module efficiency above 25 percent. This shift will likely accelerate the retirement of older, less efficient production lines. Looking ahead to 2026, Wood Mackenzie anticipates a transition from survival-driven operations to strategic investment, as global demand strengthens and module pricing stabilizes. Manufacturers holding Grade A status are expected to be well-positioned to capitalize on the next phase of global solar growth, as reliability, financial discipline, and technological advancement become central to market leadership.
This report underscores that the solar module industry is no longer defined solely by volume. Operational resilience, strategic market focus, and bankable credibility are increasingly critical for companies seeking to lead in a market that is becoming more competitive and technologically advanced.
