This utility model relates to a fixing structure for a
photovoltaic power station on a concrete
flat roof, belonging to the field of
photovoltaic power station fixing technology. The
photovoltaic power station includes multiple photovoltaic brackets arranged in a straight line at equal intervals. The two mounting ends of the photovoltaic brackets are respectively fixed to two concrete counterweights, which are fixed to the roof. A concrete
parapet wall is set on each side of the photovoltaic bracket arrangement direction, and the concrete counterweights are fixed to the roof. The two ends of the fastening cables are respectively fixed to the two concrete
parapet walls, and the fastening cables are fixedly connected to all the concrete counterweights. This solves the problem of insufficient load-
bearing capacity of the current roof for photovoltaic power stations.
