Sinovoltaics Releases 2025 Financial Stability Ranking Reports for Solar Manufacturers Amid Market Consolidation

With market consolidation and financial uncertainty reshaping the solar and energy storage industries, Sinovoltaics, a global technical compliance and quality assurance firm, has released Edition 1 of its 2025 Manufacturer Ranking Reports to help industry professionals mitigate supplier risk. The complimentary reports evaluate the financial health of solar module, inverter, and energy storage manufacturers, providing critical insights for project developers, EPCs, and investors. 

Spanning data from March 2022 to December 2024, Sinovoltaics’ latest rankings apply the Altman Z-Score, a globally recognized financial metric, to assess the financial stability of 63 PV module manufacturers, 33 inverter brands, and 59 energy storage companies. 

Developed in 1968, the Altman Z-Score predicts a company’s likelihood of bankruptcy by evaluating key balance sheet indicators. In the solar sector—where manufacturer stability directly impacts warranty enforcement and project success—Sinovoltaics’ quarterly reports help identify suppliers that are financially secure versus those that may pose a warranty-default risk. 

The key takeaways from the Edition 1 2025 ranking reports: 

• PV Module Manufacturers: The rankings reveal a growing divide between financially strong and at-risk manufacturers. While some industry leaders remain stable, many more have moved into the Grey Zone, signaling potential instability. 
• Inverter Manufacturers: Several global inverter brands continue to rank highly, but some previously dominant brands now appear in the Red Zone, indicating an elevated risk of warranty non-fulfillment. 
• Energy Storage Manufacturers: With storage becoming essential to solar projects, the rankings reveal that 46 of 59 battery manufacturers listed in the report are either in the green or grey zone. 

“With the increasing risk of bankruptcies and disappearing warranty coverage, financial due diligence has never been more critical,” said Dricus de Rooij, CEO of Sinovoltaics. “Our quarterly rankings provide a data-driven approach to help global solar project developers to identify financially stable manufacturers that can stand behind their warranties and products.” 

Sinovoltaics' 2025 ranking reports are free to download, providing developers, EPCs, and investors with data-backed insights for their solar equipment purchasing decisions. Download the reports at:  www.sinovoltaics.com/manufacturer-ranking-reports.
