Gao Weimin, vice-president of Hanergy Holding and CEO of its solar vehicle business division, said with five to six hours of sunlight, the thin-film solar cells on the four models, which cover 3.5 to 7.5 square meters, are able to generate eight to 10 kilowatt-hours of power per day, allowing them to travel around 80 kilometers, which satisfies the need to drive in a city under normal circumstances.

The models are expected to reach the market in two or three years, Gao said.

"It (Hanergy) is a very good storyteller. This leaves a great deal to the imagination," said Zhang Yu, managing director of Automotive Foresight Co.
