Based on the results, the NPC of the wind and solar system with hydrogen storage was $697624 and the year-round maintenance cost was $93836 over the 20-year period of operation.
The total cost per kWh (COE) cost of the system was $0.02, which required on-demand load of 36 kW of photovoltaic cells and a 3-unit wind turbine with a 12 kW converter. Given the decision parameters of the second scenario, the analysis is acceptable and the analysis for the second scenario is continued.

The cost of investing in the components of the hybrid system

 The total construction cost at NPC will be $697624 over the 20-year lifetime of the solar / wind hybrid power plant.
