PROBLEM TO BE SOLVED: To provide a power generation installation, making use of solar energy, whose economical effect is high by a method wherein a storage battery which shares a solar cell and an inverter is installed and the storage battery can be charged with the generated power of the solar cell. SOLUTION: In a power generation installation making use of solar energy, a solar cell 8 is linked to a power system, and electric power is supplied to low-voltage loads 6, 6. In the power generation system, a storage battery 12 and a received-power detector 5 are installed, the storage battery 12 is discharged when electric power supplied from the power system exceeds definite electric power, the discharge operation of the storage battery 12 is stopped when the electric power is at the definite electric power or lower, and the storage battery 12 is charged at any time. |
