Description |
Notice to Proceed |
Inputs specified in the project Setup |
Expected Commercial Operation Date |
Input specified in project Setup |
Generator Nameplate |
Generator Nameplate represent the total capacity of the solar array, at the COD date. This will be the capacity specific in the inputs. It represents MW_dc capacity. |
Capital expenses |
Capital expenses is the sum of solar and solar-dedicated inverter capital expenses, in year 0. Capital expenses excludes replacement costs. |
Useful life |
Useful life is the project lifetime, which is set to be equal to the lifetime of the PV array |
Derate factor |
Derate factor is a scaling factor that HOMER applies to the PV array power output to account for reduced output in real-world operating conditions compared to the conditions under which the PV panel was rated. |
Annual Solar Energy Production
Variable |
Description |
Solar Energy Production |
Solar Energy Production is the annual production from the PV array. If it is a DC-coupled system, production is MWh-dc; if the system is AC-coupled, production is MWh-ac. |
Clipped Solar Energy |
Clipped Solar Energy is the dc clipping from the solar dedicated converter. This will not include clipping from the system converter or the interconnection limit. |
Energy Yield |
Energy Yield is the Solar Energy Production divided by the Generator Nameplate capacity. |
Cumulative Degradation |
Cumulative Degradation shows how the PV array degrades over time. 100% means that the system has not degraded at all. |
Capacity factor |
Capacity factor is the arithmetic mean of the annual power output divided by the Generator Nameplate capacity. |
Operating expenses |
Operating expenses are the sum of the solar operating expenses, including the solar dedicated converters costs |
