Tesla is ramping up its clean energy efforts in China by equipping its newly-opened Shanghai Megafactory with a distributed photovoltaic (PV) and energy storage system. The installation, which is expected to be completed by the end of 2025, will include a 6-megawatt (MW) rooftop solar array and an 8-megawatt-hour (MWh) Tesla Megapack energy storage system.
Located in the Lingang New Area, the Shanghai Megafactory is Tesla’s first energy storage manufacturing site outside the U.S. and serves as the primary global production hub for the Megapack, Tesla’s utility-scale battery system. The new solar-plus-storage project will allow the facility to consume 100% of its solar-generated electricity on-site, with excess energy stored in the Megapacks for later use during peak demand or outages, according to a report from Sina.
The project is being developed by Lingang Green Innovation Co., a subsidiary of the Shanghai Lingang Economic Development Group. It represents the first large-scale industrial microgrid in the region and a significant milestone in Shanghai’s push toward distributed renewable energy.
The Shanghai Megafactory installation is part of a broader push by Tesla to integrate solar power and energy storage across its global operations. In the United States, Tesla has already installed a similar setup at Giga Texas, where a massive rooftop solar array spells out the word ‘TESLA’ and is complimented by a Megapack installation with 131MW of power capacity and 262 MWh of power storage capacity.
That installation is one of the largest rooftop solar arrays in the U.S. and helps power factory operations using clean energy.
Construction on the Shanghai Megafactory began in May 2024 and the site began operations in early 2025, ahead of schedule. The site has an annual capacity of 10,000 Megapacks—or around 40 gigawatt-hours (GWh) of energy storage—matching the output of Tesla’s other Megafactory in Lathrop, California.
