Sensitivity Results
The Sensitivity Cases table on the Results page ranks all the feasible systems from HOMER's sensitivity analysis. A sensitivity analysis can result in a large amount of output data. Every simulation that HOMER performs results in several dozen summary outputs (like augmentation % or capital cost) plus about a dozen arrays of time series data. HOMER typically performs hundreds or thousands of these simulations per sensitivity case.
The highest net present value simulation for each sensitivity is displayed in the sensitivity table and includes Configuration and sizing metrics, revenue, cost, and project economics.
Double click on a row to see all different system configurations calculated for that sensitivity case.
Configuration and sizing metrics
| PV Solar (MW) | Energy Storage | Converter | Solar Converter | Storage Converter |
|---|---|---|---|---|
| total installed DC size | total installed MW/MWh size | total capacity in MW | size in MW or size relative to the solar total installed size, also known as PV to Converter Ratio | size in MW, relative to the energy storage capacity. This is analagous to the C-rate, which is the storage power/storage energy capacity. The units for C-rate are 1/hour |
Revenue
The sensitivity table will includes a revenue section that will display the revenue associated with each selected Application or market. The revenue may include:
- one or more selected energy markets
- the capacity and energy revenue from a capacity market,
- and the revenue from a time of delivery power purchase agreement.
Cost
- Capital expenses in year 0
- Operating expenses, annualized
| NPV (Net Present Value) | IRR Internal rate of return (%) | Payback Time |
|---|---|---|
| The present value of all costs of installing and operating the system over the project lifetime in ($) | The discounting rate that makes the Net Present Value equal to zero (%) | The simple payback time in years that it takes to recuperate the capital expenses from year 0 |
