The 29.64 MW array will cover a 360,000-sqm facility owned by Dongfeng Nissan in Guangzhou.
The canopy will provide shelter for 10,000 finished car parts, as well as staff vehicles.
“This decentralized solar project will generate both economic as well as environmental benefits,” Kangping Chen, chief executive of JinkoSolar, said in an online statement.
The array is expected to generate 28.65 million kWh of electricity per year, which will be enough to cover most of the facility’s usage.
JinkoSolar estimates that the project will contribute to annual electricity cost savings of roughly 2.3 million yuan ($334,350).
The Tier-1 panel supplier posted revenue of $855 million in the third quarter, as it topped the global PV industry with 1.6 GW of module shipments.
The vertically integrated group has secured a number of major deals in the US market in recent months, including a 140 MW order for a project near Minneapolis and a 560 MW master module supply agreement with Consolidated Edison Development.
