<p>PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system that enables a cable to be easily handled in wiring, and thereby improves work efficiency and saves the space.SOLUTION: A photovoltaic power generation system 1 includes: a plurality of solar cell modules 2; a plurality of connection boxes 3 which are electrically connected to the solar cell modules 2; a power collection box 4 which is electrically connected to the connection boxes 3; an inverter 5 which is electrically connected to the power collection box 4; and a linkage transformer 7 which is electrically connected to the side of the inverter 5 and also has its output terminal electrically connected to the side of a system linkage point CP. Cables which are wired among the solar cell modules 2, connection boxes 3, power collection boxes 4, and inverter 5 all have a voltage drop of 3% or lower; and cables which are longer length than other cables among the cables include conductors 51 having a thinner diameter than those of the other cables, and cables which are shorter in length than other cables include conductors 51 having a thinner diameter than those of the other cables.</p> |
