After you click Next and the calculation is complete, HOMER will display the results in table format. If you have included a sensitivity, double-click to view all the feasible simulations that were run for the selected sensitivity case to open the Optimization Results table.
The highest net present value simulation for that specific sensitivity is displayed in the table and includes the following metrics.

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 Optimization Results table includes a Revenue section that will display the revenue associated with the selected system. Depending on the Application or selected Energy markets, 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
The Optimization Results table includes a Cost section that displays the capital and operating expenses for the selected simulation.
▪Capital expenses in year 0
▪Operating expenses, annualized
