The project is expected to generate an average of 21.33 million kilowatt hours of electricity per year, equivalent to the power used by more than 50,000 people for one year.

Notably, Xpeng is not the first car company to cut carbon emissions with photovoltaic power, as its local counterpart Nio began installing solar panels on the roof of its battery swap stations late last month.

Unisun Energy, a provider of distributed clean energy plant solutions, said it signed a contract with Nio on October 19 at the latter's global headquarters in Shanghai to install rooftop distributed photovoltaic panels on the EV maker's second-generation battery swap stations.

Unisun Energy's release shows that it is installing an average capacity of 100kW per PV station on the roofs of battery swap stations for Nio.

By the end of 2025, when Nio has more than 3,000 battery swap stations in China, the total PV capacity on the roofs of these facilities will reach 300 MW, Unisun Energy said.

At the inaugural Nio Power Day event on July 9, Nio announced that by the end of 2025, the company will have more than 4,000 battery swap stations worldwide, including 1,000 in overseas markets.
