In the PV module category, 11 producers are now considered financially sound, up from 9 previously, while the number of companies in the distress zone has risen slightly from 26 to 27. In the inverter market, 19 manufacturers show strong financial resilience, compared with 15 in the previous edition.KSTAR and APsystems maintain the strongest performance, followed by Delta Electronics.China's Sungrow has also demonstrated notable improvement, with its Altman Z-score rising to 4.81 since June 2025. The energy storage sector continues to strengthen as well, with 23 companies now in the safe zone, up from 21.
Firms such as Sinexcel, Sacred Sun, EnerSys, and Yuasa Batteryhave maintained steady financial positions.However, Albemarle, based in the United States, is experiencing margin tightening and increased leverage pressure. According to Dricus de Rooij, CEO of Sinovoltaics, "Financial resilience is now the new competitive edge in the industry.Amid oversupply and market consolidation, the ability to sustain profitability and honor long-term warranties will separate reliable manufacturers from the rest." Sinovoltaics uses the Altman Z-score to assess financial health based on profitability, leverage, liquidity, solvency, and activity ratios.
A score below 1.1 indicates a higher risk of bankruptcy within two years, while a score of 2.6 or higher reflects strong financial stability.
