1. Product:
Solar Powered Air-conditioning System for Vehicles (SAV)
The present project is an air-conditioning system designed to be installed
in vehicles. 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 retrofitting and without deteriorating the overall performance
and affecting other components.

2. 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 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 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:
 Engine is not related directly to the air-conditioning system (Two units
are decoupled)
 Air-conditioning system can be functioning when engine is at still
 Renewable energy used
 Compressor and motor are controlled by the needs of air-conditioning
(VSD used)
 Cost saving from reduction in fuel consumption
 Longer milage per fuel tank Emission reduction
 Extend engine and air-conditioning compressor life expectancy
 Encourage drivers to cut engines when vehicle is at still
 Extend public life expectancy Counter Fuel price (the higher the fuel
price the more value)
SAV is designed to integrate with vehicle’s air-conditioning with solar
energy capabilities as one system for vehicle including: Truck, Lorry,
Private Car, Buses and utility vehicles. The SAV system is based on the
all-electric concept that is able to provide air-conditioning during the
turn-off of the main engine of a vehicle The power is supplied from a
battery or solar cell in order to ensure no-emission during the vehicle
stands still or is in waiting.
