Thin-film solar PV company Hanergy Holding Group (Beijing, China), on July 2nd, 2016 announced the launch of four full solar power vehicles at a ceremony named “Disruptive Innovations Drive the Future”. Over 4,000 guests from all sectors of society attended the event, Hanergy emphasizes.
A sports car named “Hanergy Solar R” made its debut as Li Hejun, Board Chairman and CEO of Hanergy Holding Group, drove it around the venue in the spotlight.
In his speech, Mr. Li elaborated on the advantages of thin-film solar cells such as light weight and flexibility, enabling the cells to be integrated into a variety of products such as cars, unmanned aerial vehicles, mobiles, backpacks and clothes.
Thin-film solar cells and PV modules integrated into vehicles
The full solar power vehicles making their debut showcase the latest achievements of Hanergy's mobile energy strategy, he said.
Integrated with flexible and highly efficient thin-film solar cells and PV modules, the full solar power vehicles with zero emissions use solar energy as its main source of driving force through a series of precise control and managing systems, including a photoelectric conversion system, an energy storage system and an intelligent control system, Hanergy notes.
“As Hanergy's full solar power vehicles acquire power directly from the sun, they do not depend on charging posts and thus have no need to bother with ‘distance per charge’ anymore, making ‘zero charging’ possible during medium and short distance journeys,” reads the press release.
According to Hanergy, the four vehicles are the first full thin-film solar power vehicles that can be commercialized.
31.6% efficiency dual-junction solar cell recognized NREL
With a conversion rate of 31.6%, Hanergy's gallium arsenide (GaAs) dual-junction solar cell was awarded with a World Record Certificate by the World Record Association at the launch event.
The technology had previously been recognized by the National Renewable Energy Laboratory (NREL) of the United States for its world's highest conversion rate on January 5th, 2016.
Hanergy also signed a framework agreement with Foton Motor for cooperation in developing clean energy buses.
In addition to Hanergy Solar R, the Hanergy Solar series of vehicles launched on Saturday evening also included Hanergy Solar O, Hanergy Solar L and Hanergy Solar A, targeted at different groups of users.
According to Dr. Gao Weimin, Vice President of Hanergy Holding Group and CEO of its Solar Vehicle Business Division, the four full solar power vehicles are integrated with flexible GaAs thin-film solar cells, covering 3.5 to 7.5 square meters respectively.
With five to six hours of sunlight, the thin-film solar cells on the vehicle are able to generate eight to ten kilowatt-hours of power a day, allowing it to travel about 80 km, equivalent to over 20,000 km annually.
