In HOMER, two independent factors may limit the lifetime of the storage bank: the lifetime throughput and the storage float life. In other words, batteries can die either from use or from old age. When you create a new storage component, you can choose whether the storage lifetime is limited by time, throughput, or both.
HOMER calculates the storage bank life using the following equation:
where: |
|
|
|
Rbatt |
= storage bank life [yr] |
|
Nbatt |
= number of batteries in the storage bank |
|
Qlifetime |
= lifetime throughput of a single storage [kWh] |
|
Qthrpt |
= annual storage throughput [kWh/yr] |
|
Rbatt,f |
= storage float life [yr] |
