Photovoltaic (PV) power generation has increased as the institutions to subsidize and purchase surplus electricity have been introduced. Environmental awareness has also played a part. To increase this trend there is a need to reduce installation costs. Consequently there is a need for standardization of system components.
In our country manufacturers have been developing mainly domestic and small industrial sized units. Inverters of 4 kW for small units and 10 kW with master-slave function for large units are being produced on a large scale. This means that installation costs are being reduced for these specific unit sizes but not for the other sizes. In Europe, AC module that integrates inverter has been developed. It can then be added to produce a generation plant of any required size.
In this paper, we have calculated annual power output and power generation costs of these different inverter systems. PV modules, PV arrays and inverters of various sizes have all been compared in an attempt to determine the most cost-effective system. The results revealed that the power output of AC modules system is sufficiently high as well as providing the cheapest generating cost.
