The solar photovoltaic air conditioning system was built successfully with all of its part which includes the inverter which converts the current from direct current into alternative current to pass it then to the transformer which increases the voltage on the expense of the current to reach the required voltage and definitely the power to operate the system. The performance of any mechanical system must be evaluated to make sure that the system works successfully, in air conditioning design the COP (Coefficient Of Performance) must be calculated and here we got COP for the system about 5.1 and comparing it with another works, the computer program gave a result for the COP equals to 42 which is nearly the same taking in consideration that our systems data were taken for a period of 24 hours and the average of them were taken as the final results.
