PHOTOVOLTAIC ELECTRICITY GENERATION SYSTEM AND METHOD OF OPERATING SAME TO PERFORM PHOTOVOLTAIC ELECTRICITY GENERATION

摘要

The disclosed embodiments provide a photovoltaic electricity generation system, the photovoltaic electricity generation system (100) comprising: an electricity conversion apparatus (120), having a first input (121) and a second input (122); and a DC module (110), the DC module (110) comprising: a bus bar (150); and an upper bridge unit (130) and a lower bridge unit (140) sharing the bus bar (150) and mutually connected in parallel with respect to the bus bar (150); and a circuit formed between the upper bridge unit (130) and the bus bar (150) and a circuit formed between the lower bridge unit (140) and the bus bar (150) capable of respectively generating DC electrical energy according to incident light respectively received thereby. The present disclosure further provides a method of operating the above photovoltaic electricity generation system in order to perform photovoltaic electricity generation. The disclosed photovoltaic system and electricity generation method of the embodiments can enable independent control of photovoltaic modules comprised in mutually independent control circuits according to sunlight or a state of the photovoltaic module, thereby markedly advancing the efficiency of photovoltaic electricity generation.
