Carbon has emerged as a third actor in the ongoing patent dispute between rival Chinese manufacturers JA Solar and Astronergy.

JA Solar filed two lawsuits at the German offices of the Unified Patent Court (UPC) against fellow Chinese solar manufacturer Astronergy in July.

Chinese module manufacturer JA Solar has inked a 1GW solar PV module distribution agreement with Australia’s One Stop Warehouse (OSW), covering the European, US and Asia-Pacific markets.

JA Solar has supplied 1.1GW of modules for two animal husbandry and what it calls “PV complimentary” projects in the Latuo County of Tibet.

The company filed two complaints in the Munich and Hamburg local divisions of the UPC, regarding tunnel oxide passivated contact (TOPCon) solar cell patent infringements.

The modules are being shipped to SolarPro, a Bulgarian engineering, procurement and construction (EPC) company which specialises in renewable and hybrid energy projects.
