Authors: Nguyễn Thùy Linh*, Lê Thị Minh Châu, Nguyễn Duy Khiêm, Trần Đình Long


In grid-connected rooftop photovoltaic power systems, the generated electricity from these power systems can be sold to the electricity serving ultity. This arrangement provides payback for investors to be able to take the investment of their PV power system installation back and the payback period of the rooftop PV power system installation depends on the tariff policy as well. In this paper, the impact of three main factors of the tariff policy are considered such as: (1) the Feed-in-tariff policy for renewable resources in general and for the solar energy in particular, (2) Block meter tariff and (3) time-of-use tariff.
