    This paper analyses the economics of 50kW PV system installed in Tibet and using domestic technology. We show that this system can be expanded to very large-scale photovoltaic power generation [VLS-PV] system successfully. Based on this result, we conduct the economic analysis of 100MW VLS-PV system designed assuming that it will be installed from 2008 to 2017 in Tibet. In this analysis, future price of PV module and system are estimated based on the methodology of experience curve. In 50kW PV system, the generation cost is calculated at 567.2 won/kWh and this is lower than the one of domestic PV system. In future 100MW VLS-PV system. the generation cost is calculated at 305.4 won/kWh by declining system price. If the lifetime and efficiency of the system goes up, due to future technological improvements, the generation cost can be lowered. Moreover, under the environmental and political effect, VLS-PV system can be as competitive as the conventional energy within 20 years.
