Solar photovoltaic (PV) system

An electricity generation system which converts sunlight into
electricity by the use of photovoltaic (PV) modules. Thesystem also includes ancillary equipment such as inverters
required to change the electrical current from direct current(DC) to alternating current (AC).

F.1. Establishment of reference emissions
The default emission factors are set in a conservative manner based on the Viet Nam’s nationalgrid. The emission factor is calculated based on the recent three years of electric power sourcemix published by Vietnamese government identifying 1) primary fuel type which has the largest
volume of generated electricity among the fossil fuel types used as a source and 2) the best heatefficiencies derived from the type of power plants currently operational in Viet Nam according
to the identified primary fuel type.
As a result, the emission factor of 0.333 tCO2/MWh is applied which is calculated based on theheat efficiency of the most efficient natural gas-fired power plant supplying electricity to thenational grid. The value is lower than the emission factor of the Viet Nam grid published by thegovernment of Viet Nam, which is 0.8154 tCO2/MWh (combined margin, 2015), and ensures
net emission reductions.
In addition, the emission factor of a diesel power generator is calculated by applying the default
heat efficiency of 49%, an efficiency level which is above the value of the world’s leading2
