The renewable fraction is the fraction of the energy delivered to the load that originated from renewable power sources.
Type: |
Output Variable |
Units: |

HOMER calculates the renewable fraction using the following equation:
where: |
||
|
Enonren |
= nonrenewable electrical production [kWh/yr] |
|
Egrid,sales |
= energy sold to the grid [kWh/yr] (included in Eserved) |
|
Hnonren |
= nonrenewable thermal production [kWh/yr] |
|
Eserved |
= total electrical load served [kWh/yr] |
|
Hserved |
= total thermal load served [kWh/yr] |
HOMER abbreviates the renewable fraction as "Ren. Frac." in the Sensitivity and Optimization Results tables.
