A solar power plant generates optimal output when it receives radiation (sun peak hours) of 1000 W/m², following Standard Test Conditions (STC), and when all production equipment operates efficiently. The equipment will function well if optimal maintenance is performed.
According to project planning data, the estimated maintenance cost is USD 22/kWp per year. However, the initial project data does not specify the maintenance activities required for the plant. Solar power plants are generally considered low-maintenance, typically requiring only routine maintenance. Optimal expenditure is necessary to maintain the health of the plant’s equipment, ensuring that production output remains optimal.
Based on cost management principles [1], the life cycle cost (LCC) method can be used to calculate the total expenses incurred throughout the plant’s lifespan, which can then be compared to total production over the same period. This study examines both investment costs and maintenance activities. A simu
