Solar photovoltaic (PV) system

An electricity generation system which converts sunlightinto electricity by the use of photovoltaic (PV) modules.
The system also includes ancillary equipment such as
inverters required to change the electrical current fromdirect 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 0.5657 tCO2/MWh (combined margin, 2013), and ensures
net emission reductions.
In addition, the emission factor of a diesel power generator is calculated by applying the mostefficient heat efficiency of 49%, an efficiency level which has not been achieved yet by theworld’s leading diesel generator, and set to 0.533 tCO2/MWh.

RE୮ = ෍൫EG୧,୮ × EFୖ୉,୧ ൯୧

REp: Reference emissions during the period p [tCO2/p]

EGi,p: Quantity of the electricity generated by the project solar PV system i during theperiod p [MWh/p]

EFRE, i : Reference CO2 emission factor for the project solar PV system i [tCO2/MWh]

G. Calculation of project emissions
Project emissions are not assumed in the methodology as electricity consumption by any PV
system is negligible.
PEp = 0PEp

: Project emissions during the period p [tCO2/p]

H. Calculation of emissions reductions
ERp = REp − PEp= REp
ERp: Emission reductions during the period p [tCO2/p]

REp: Reference emissions during the period p [tCO2/p]

PEp: Project emissions during the period p [tCO2/p]
