The development policy of the
photovoltaic power plant of government strongly impacts to NPV and LCOE.
According to the policy tariff, either selling the total electricity generated
or consuming (FiT). The values in different countries with a FiT rate is shown
in Table 2, as well as the years supported. From Table 1, the country has the
best FiT rate in Japan (0.297 USD/kWh) and the worst FIT rate in the UK (0.052
USD/kWh). However, the simulation tool is playing an essential role in the
economic analysis of the renewable energy system.

In April 2020, the Vietnamese government issued a new policy
for solar power projects as shown in Table 2. According to Table 2, the FIT
rate of electricity for rooftop solar power projects is the highest. This
indicates that the government is further rooftop solar power projects. Next are
floating projects.
