12.SOUNDBITE ( English ) Eric Cheng, professor of Department of Electrical Engineering at Hong Kong Polytechnic University ” The solar-powered panel on the top accounts for 1.5 kilowatt for energy. Then if you got a full day, then this energy can have quite a number of kilo-hours, probably up to 6 or 7 kilo-hours, so this energy are able to support for vehicles for run for air-conditioning for quite a few hours. So usually for vehicles for energy you don’t have to run for 24 hours, you may just run for a few hours, in this case, it’s good enough to support the energy requirement for air-conditioning.”

” The one in the buildings, they are using a technology�.using a metal frame, aluminum frame for the couture, but however their size would be too big for vehicle. You can see this vehicle we use a very low profile very thin one so that to fit on top of a vehicle. Our design is quite special we use aluminum substrate to mount the solar shell on there, in order to make them very thin, they are able to make a curvature well so that they can fit really well on the vehicle. In this case we can optimize the performance, we can put more solar shells we don’t have any problem with the structure or the outlook of the vehicle as well.”

A solar-powered air-conditioning system for different types of vehicles has been developed in Hong Kong.
Researchers say the innovation has provided a practical solution to providing green energy for the much-needed in-car air-conditioner needed for city driving.
STORYLINE:
This could be the way vehicles will look in future.
Not the sleekest of designs but these photovoltaic modules on top of the van are using solar energy to cool the interior of the vehicle.
As it moves along the road, it automatically harvests solar energy for storage in a specially made battery system supported by an optimized control system.
The power collected supports a stand-alone electric air-conditioner, which can be switched on when the car engine is not running.
The sophisticated system can also operate during cloudy or rainy days because solar energy is automatically stored in the battery during sunny weather.
The device has been developed at the Hong Kong Polytechnic University.
Professor Eric Cheng of the University’s Department of Electrical Engineering headed the innovation project. He says air-conditioning usually accounts for one-third of the energy consumption of vehicles.
The energy loss is much higher for vehicles with more windows.
