Large-scale solar power generator

Disclosed is a large-scale solar power generator construction installation in which the transmission systems of primary or secondary commercial power systems are interconnected. A large number of solar battery arrays are aligned and laid with spaces provided between columns. Base units that gather/collect and output power generated by a prescribed number of solar battery arrays are formed in column units. Collection installations that gather/collect the output for each of a prescribed number of the base units are installed in a plurality of the column units. The plurality of collection installations installed in each column are connected by collection lines, and the collected power generated by the collection installations is further gathered/collected and output to intermediate substations installed corresponding to the columns. At the intermediate substations, the voltage is boosted to an intermediate voltage and output to intermediate transmission lines, the output of the plurality of intermediate substations is thus collected by the intermediate transmission lines and output to an interconnection substation, and the interconnection substation boosts the voltage to a primary or secondary transmission voltage.
