Fuji Solar Co., Ltd. is a solar energy solutions provider, primarily known for its involvement in the manufacturing and installation of solar panels and inverters. The company operates as a subsidiary of the Japanese renewable energy firm Abalance Corporation, which is headquartered in Tokyo, Japan. While specific founding details for Fuji Solar Co., Ltd. are not readily available, its parent company, Abalance Corporation, is a publicly traded entity. Other entities with similar names, such as FUJI SOLAR CO., LIMITED (based in Hong Kong) and Fuji Solar Inverter Technology Co., Ltd. (operating in China), also engage in solar product manufacturing, producing inverters for residential and commercial photovoltaic power systems.
Fuji Solar Co., Ltd. and its related operations focus on comprehensive photovoltaic power system solutions. Their product offerings include a range of solar panels, PV grid-connected inverters (1.5-110kW), hybrid inverters (3-12kW), and microinverters (300W-2000W). The company also provides design, installation, and assembly services for solar energy systems, catering to both residential and commercial power plant solutions.
In terms of patent litigation, Fuji Solar Co., Ltd. has appeared once as a defendant in the United States District Court for the Northern District of California. This indicates its posture as an operating company defending against intellectual property claims rather than a non-practicing entity.
The notable case involving Fuji Solar Co., Ltd. is Shanghai Jinko Green Energy Enterprise Management Co LTD et al. v. VSUN Solar USA Inc. et al. In this lawsuit, filed in December 2024, Chinese solar panel manufacturer JinkoSolar accused Fuji Solar Co., Ltd., along with its parent Abalance Corporation, VSUN Solar USA Inc., and other affiliates, of infringing two patents related to solar cell technologies. The dispute has since been settled as of January 2026.
