Economic Injury Product Defect

Lieff Cabraser’s Economic Injury Product Defect practice group is investigating multiple reports that TOPCon Solar Power Modules are showing signs of accelerated degradation.

Key manufacturers using TOPCon panels are:

• LONGi Green Energy Technology Co. Ltd.
• Trina Solar Limited
• JinkoSolar Technology Co. Ltd.
• Canadian Solar Inc.
• First Solar Inc.
• Avaada Electro Pvt. Ltd.
• HVR Solar Pvt. Ltd.

Consumers of these and other solar panel brands containing TOPCon panels claim TOPCon solar modules are experiencing significant accelerated degradation, particularly in damp heat testing, with power losses reaching as high as 65% in as little as 1,000 hours. Described failure modes include localized corrosion, interfacial failures at ribbon-wire connections, and widespread cell degradation driven by electochemical reactions, particularly in humid environments.

If you or a family member have experienced degradation in home solar heating panels from any of the above manufacturers, we urge you to use the form below to talk to a lawyer at Lieff Cabraser about your case and potential recovery.
