This paper is a study of comparisons between five types of 100 MW Very Large-Scale Photovoltaic Power Generation (VLS-PV) Systems, from economic and environmental viewpoints. The authors designed VLS-PV systems using typical PV modules of multi-crystalline silicon (12-8% efficiency), high efficiency multi-crystalline silicon (15-8%), amorphous silicon (6-9%), cadmium tellurium (90%), and copper indium selenium (110%), and evaluated them by Life-Cycle Analysis (LCA). Cost, energy requirement, and CO2 emissions were calculated. In addition, the authors evaluated generation cost, energy payback time (EPT), and CO2 emission rates. As a result, it was found that the EPT is 1-5-2-5 years and the CO2 emission rate is 9-16g-C/kWh. The generation cost was 11-12 US Cent/kWh on using 2 VSD/W PV modules, and 19-20 US Cent/kWh on using 4 USD/W PV module price.
