In HOMER, the lifetime of generators, or generator operational life, is specified in terms of operating hours. The number of years that a generator lasts is, therefore, an output variable, which HOMER calculates according to the following equation:
where: |
|
|
|
Rgen,h |
= generator lifetime [hr] |
|
Ngen |
= the number of hours the generator operates during one year [hr/yr] |
For example, if the generator has a lifetime of 20,000 operating hours and HOMER determines that it operates 4,300 hours per year, its expected lifetime in years is 20,000 hours divided by 4,300 hours per year, which is 4.65 years.
