We are specialized in research and development cutting edge environmental friendly technologies which can be applied into daily used. Collaborating with the Hong Kong Polytechnic University in development of new sustainable energy technologies, these technologies are Taylor for the present market niche. With our vision to anticipate the customers’ needs and dedicated to the customer’s success. Our ultimate goal is to reduce the green house gas emission by transforming/replacing daily energy consuming systems to power by renewable energies. Our research and development team work closely with Professor Eric Cheng whose specialize in electrical engineering and his fellow teams, consolidating the knowledge and skills of both commercial and research driven party has maximized our capabilities into explore and realizing new technologies to improve our life. The Hong Kong Science and Technology Park provides rich research and development stage for Green Power Industrial by providing cutting edge laboratory and development facilities to be used.

Solar Powered Air-conditioning System for Vehicles (SAV)

The present project is an air-conditioning system designed to be installed in vehicle. The air-conditioning system derives power from solar cell and the electric power is used to drive the electric motor with compressor to produce the cooling. The solar cell is also installed with maximum power point tracking (MPPT) for the battery charger. The system provides a new method of solar driven system together with the existing power system in a vehicle. Invention provides a method to work with the existing system based on a retrofitting and without deteriorating the overall performance and affecting other components.

The conventional air-conditioning system for petrol/diesel vehicle is driven by the internal combustion engine (ICE). The dynamic control of the Vehicle Air-conditioning System (VAS) is usually not implemented because the speed control of the ICE to the VAS is not set up. Therefore the variable speed control in order to provide better efficiency of the VAS is not realized. The energy to drive the VAS is classically from the petrol which produces green house gases. Solar panel and is also called photovoltaic panel is now being used in many green products. One of the main applications is to use on mobility. The electric vehicle is one of the major applications. It is also being used in static power source such as installed in building or ground which the panel is to collect the solar power and convert to the electric power. The power can be used directly or stored in energy storage devices such as battery or super-capacitor.

Benefits from application of SAV to Vehicles:
