Solar photovoltaic (PV) system

An electricity generation system which converts sunlightinto 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).

Generation of electricity from the solar PV system(s)N/AF. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
The default emission factors are set in a conservative manner based on the Costa Rican national
grid and the most efficient heat efficiency of a diesel power generator to ensure net emission
reductions.
In order to identify the emission factor based on the national grid simplistically and secure netemission reductions, this methodology applies the conservatively calculated emission factor of adiesel-fired power plant based on a default heat efficiency of 49%, an efficiency level which isabove the value of the world’s leading diesel power generators, to the actual electricity
dispatched from diesel power plants to the national grid in the year 2013-2015.
In case the PV system(s) in a proposed project is connected to the national grid including

through internal grid which is not connected to a captive power generator, or the PV system(s)in a proposed project is connected to internal grid which is connected to both the national gridand a captive power generator, the value is set to be 0.255 tCO2/MWh, which is lower than thelatest official emission factor calculated for a CDM project in Costa Rica, which is 0.273

tCO2/MWh (combined margin, 2010-2012).
In case the PV system(s) in a proposed project is connected to an internal grid which is notconnected to the national grid, the emission factor of a diesel generator calculated by applying
the most efficient heat efficiency of 49%, an efficiency level which has not been achieved yetby the world’s leading diesel generator is applied, which is set to 0.533 tCO2/MWh.

F.2. Calculation of reference emissions

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 emission factor for the project solar PV system i [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
