In particular, areas that are free for other areas than the obstacle areas in the roof area can be used for installing the photovoltaic power station and are therefore determined as areas to be installed. In addition to this, not all areas in which obstacles are placed can be completely unusable, and for the obstacle areas corresponding to the movable obstacles, after the obstacles have been removed, they can be used for installing the photovoltaic plant, so that the obstacle areas corresponding to the movable obstacles can also be determined as installable areas. If the obstacle region corresponding to the immovable obstacle meets the condition, the obstacle region can also be used for installing the photovoltaic power station, so that the obstacle region corresponding to the immovable obstacle meeting the preset condition can also be determined as an installable region. It will be appreciated that in areas of the roof other than the mountable areas are non-mountable areas. For example, an obstacle region corresponding to an immovable obstacle that does not satisfy a preset condition.
Optionally, the preset conditions include: the difference value between the height of the barrier area corresponding to the immovable barrier and the average height of the roof area is smaller than a preset threshold value; the preset threshold value is determined by the position of the barrier area on the roof and the installation angle of a photovoltaic assembly of the photovoltaic power station.
Specifically, because photovoltaic power plant's photovoltaic module sets up certain installation angle through can when the installation in order to receive more illumination, consequently photovoltaic power plant highly has certain difference in height in different regions.

space＝(area_y-roof_y)×tan(α)；
wherein alpha is the installation inclination angle of the photovoltaic power station and is determined by the north and south lengths of the special-shaped roof; space is a preset threshold.
And S260, determining a target installation position of the photovoltaic power station on the roof according to the area to be installed.

Since the photovoltaic module requires support of the pillars corresponding to the pedestals, the layout of the photovoltaic module is determined according to the layout of the pedestals.
For example, the method for determining the target layout of the photovoltaic power station at the target installation position according to the area to be installed may be: for an installable area in the area to be installed, setting the position of the column foot according to the shape and the position of the obstacle, the movable state and the framework of the photovoltaic power station; the non-mountable area in the area to be mounted can be free of column feet, and accordingly, the photovoltaic module cannot be supported.
S280, determining a target cable connection route of the photovoltaic power station according to the cable length required by the photovoltaic power station under the target layout.
Specifically, after the target layout of the photovoltaic power station is determined, the target cable connection route of the photovoltaic power station needs to be determined according to the cable length required by the photovoltaic power station under the target layout, so that the required cable length of the photovoltaic power station is minimized, and the cable cost is saved.
