The proposed concept of the system consists of air conditioner and PV system is indicated in block
diagram shown in Figure 1. In order to determine the characteristics and properties of all the components
used, each component must be taken as a single unit.
The complete system must be able to operate in stable condition, and if possible achieving the
efficiency as conventional air conditioning system. For example, as for the cooling purpose, performance
of the DC air conditioning should be the same as normal AC air conditioner.
