The generator average electrical efficiency is the average of the generator's electrical efficiency over a year, defined as the electrical energy out divided by fuel energy in. HOMER uses the following equation to calculate the average electrical efficiency:
where: |
|
|
|
Egen |
= the generator's total annual electrical production [kWh/yr] |
|
mfuel |
= the generator's total annual fuel consumption [kg/yr] |
|
LHVfuel |
= the lower heating value of the fuel [MJ/kg] |
We use 3.6 in the equation above because 1 kWh = 3.6 MJ.
