Solar photovoltaic (PV) system

An electricity generation system which converts sunlight intoelectricity 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).

Generation of electricity from solar PV system(s)N/AF. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Almost all electricity in the Maldives is generated by diesel. Being an island country, almost all
the islands generated its own electricity and all grids in the Maldives are isolated. Consideringthat power from other sources such as solar PV is very limited and is negligible, net emission
reductions are ensured as follows.
It is assumed that solar PV systems installed in the Maldives will replace grid electricity and/or
captive electricity generated by the existing diesel generators whose power generation
efficiency is estimated to be around 35.4% in Male, which leads to the CO2 emission factor of0.739 tCO2/MWh.

However, applying such emission factor derived from the existing diesel generators does notachieve net emission reductions. Therefore, the power generation efficiency of 49%, which has
not been achieved yet by the world’s leading diesel generators, is employed in this methodology
to ensure net emission reductions. The emission factor of grid and captive electricity is set to0.533 tCO2/MWh based on the power generation efficiency of 49%.

F.2. Calculation of reference emissions

RE୮ = ෍ EG୧,୮ × EFୖ୉୧

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

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

EFRE: The reference CO2 emission factor of grid and captive electricity [tCO2/MWh]

G. Calculation of project emissions
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]3
