PROBLEM TO BE SOLVED: To provide an economical photovoltaic power generating and power supplying system. SOLUTION: Since one control center 20 is provided for a plurality of power generating load units 10, an expensive common battery 22 and the control center 20 may be used as one device, and cost reduction is achieved. In addition, when power shortage occurs in a part of a power generating load unit 10 due to the increase of alternating current load 13, bad weather or the failure or the like of a solar battery 11 due to disaster or the like, a commercial power source 50 may not be always used since excessive power of the other power generating load unit 10 is supplied to the power generating load unit 10 of power generating power shortage through the common battery 22, and for instance, even when power supply from the commercial power source 50 is received, the amount can be reduced. |
