In HOMER, the lifetime of generators is specified in terms of operating hours. The number of years that a generator will last 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 will operate 4300 hours per year, then its expected lifetime in years would be 20,000 hours / 4300 hours per year = 4.65 years
