As a stand-alone system, the off-grid PV system needs more energy storage batteries as backup power, which increases the NPC. Therefore, the NPC of off-grid PV systems is much higher than the NPC of grid-connected systems. From the internal cost characteristics of PV systems, the cost of batteries accounts for 31.4–48.4% in the total NPC. But the capital
