Sinovoltaics’ report evaluates the financial health and viability of global inverter manufacturers using the Altman Z-Score model — a widely recognized formula for predicting the likelihood of a company entering financial distress. APsystems not only led the industry with the highest score but also demonstrated consistent financial stability throughout the three-year analysis period, from 2022 to 2025.

“Financial viability is fundamental in the solar industry,” said Dr. Zhi-min Ling, APsystems Co-founder and President. “Installers, EPCs, and financiers need assurance that the technology they deploy today will be supported tomorrow. Our customers expect not only performance and innovation but also long-term reliability. This report confirms that APsystems will be here year after year, fulfilling that promise.”

Understanding the Sinovoltaics Ranking

The Sinovoltaics Inverter Manufacturer Ranking Report is the industry’s most comprehensive independent financial ranking for inverter companies. Using the Altman Z-Score a predictive model that assesses working capital, retained earnings, EBIT, market value, and sales the report evaluates each manufacturer’s financial stability and likelihood of survival over the next 2 to 10 years.

Manufacturers are classified into three zones: “Safe,” “Gray,” and “Distress.” APsystems achieved the highest Altman Z-Score, placing it firmly in the Safe Zone and distinguishing it from dozens of competitors worldwide.
