Definitions
- TITLE Process for determining an arrangement of photovoltaic panels on areas of a territory
- the present invention relates to a method for determining an arrangement of photovoltaic panels on areas of a territory.
- the present invention also relates to an associated computer program product.
- the estimates made are generally based on a rough distribution of the photovoltaic panels on the surfaces of interest. However, some surfaces are actually incompatible with the installation of photovoltaic panels, which distorts the estimates.
- the present description relates to a method for determining an arrangement of photovoltaic panels on areas of a territory, called target areas, the method being implemented by computer and comprising the following steps: a. reception of an image seen from the sky of a territory comprising at least one target zone, b. the detection of each target zone on the image by a segmentation of the image so as to obtain a mask of the target zones of the image, called zone mask, c. the application of the area mask to the image to obtain an image, called the target image, on which only the target area(s) of the image are represented, d. the detection of contours on the target image to obtain a mask of contours, the detected contours materializing obstacles on the target zone(s), e.
- the highlighting of obstacles on each target zone of the image by combining the zone mask and the contour mask to obtain a mask of the obstacles present on the target zone or zones of the image, called the obstacle mask, and F. determining an arrangement of photovoltaic panels on each target area of the image as a function of the mask of obstacles so as to satisfy at least one positioning constraint, the at least one positioning constraint stipulating that each photovoltaic panel covers a portion of a target area free of obstacles.

- FIG 2 Figure 2 a flowchart of an example of implementation of a method for determining an arrangement of photovoltaic panels on areas of a territory
- FIG 3 Figure 3 a schematic representation illustrating examples of images obtained at the different stages of the process in Figure 2.
- FIG. 1 A computer 10 and a computer program product 12 are illustrated in Figure 1.
- Computer 10 is preferably a computer.
- the computer 10 is an electronic computer capable of manipulating and/or transforming data represented as electronic or physical quantities in computer registers 10 and/or memories into other similar data corresponding to physical data in memories, registers or other types of display, transmission or storage devices.
- the computer 10 interacts with the computer program product 12.
- the computer 10 comprises a processor 14 comprising a data processing unit 16, memories 18 and a reader 20 for information support.
- the computer 10 comprises a keyboard 22 and a display unit 24.
- the computer program product 12 has an information carrier 26.
- the information medium 26 is a medium readable by the computer 10, usually by the data processing unit 16.
- the readable information medium 26 is a medium suitable for storing electronic instructions and capable of being coupled to a computer system bus.
- the information medium 26 is a floppy disk or floppy disk (from the English name "floppy say"), an optical disk, a CD-ROM, a magneto-optical disk, a ROM memory, a memory RAM, EPROM memory, EEPROM memory, magnetic card or optical card.
- the computer program 12 comprising program instructions.
- the computer program 12 can be loaded onto the data processing unit 16 and is adapted to cause the implementation of a method for determining an arrangement A of photovoltaic panels over areas of a territory, when the computer program 12 is implemented on the processing unit 16 of the computer 10.
- FIG. 2 schematically illustrates an example of implementation of a method for determining an arrangement A of photovoltaic panels over areas of a territory, and to the FIG. 3 illustrating certain steps of the method.
- the determination process aims to determine an arrangement A of photovoltaic panels on areas of a territory, called target areas.
- arrangement is understood to mean a number of photovoltaic panels, and an arrangement of said photovoltaic panels on target zones, namely a position and an orientation for each panel.
- Each target zone Z c typically has dimensions and a shape allowing the installation of one or more photovoltaic panels on the zone.
- Each target zone Zc is an area of an open-air territory, that is to say receiving direct solar radiation.
- a target zone Zc is a surface of a human construction.
- a target zone is therefore a zone created artificially by man, also called an entropy zone.
- a target zone Z c is a roof, a terrace or even a parking lot.
- the target areas are likely to include obstacles O on their surface (surface receiving direct solar radiation).
- the term “obstacle” is understood to mean an element present on the surface of the target zone Z c and incompatible with the arrangement of a photovoltaic panel on this element. Obstacles O are, for example, chimneys, windows (velux), air conditioning systems or even vegetation (trees, plants).
- the determination method comprises a step 100 of receiving an image IM seen from the sky of a territory comprising at least one target zone Zc.
- Step 100 is implemented by the computer 10 in interaction with the computer program product 12, that is to say is implemented by computer.
- the IM image was, for example, acquired by a satellite system.
- the IM image was acquired by an acquisition system (camera) mounted on an aircraft.
- the IM image is typically a georeferenced image, i.e. each pixel of the IM image is associated with a latitude and a longitude.
- the image IM is a two-dimensional image.
- the image IM is a color image.
- FIG. 3 illustrates an example of an image IM of a territory comprising three target zones Z c .
- Each target zone Z c includes obstacles O which will be highlighted later in the method.
- the determination method comprises a step 110 of detecting each target zone Zc on the IM image by segmenting the IM image so as to obtain a mask of the target zones Zc of the IM image, called zone mask M_Zc .
- Step 110 is implemented by the computer 10 in interaction with the computer program product 12, that is to say is implemented by computer.
- the segmentation is, for example, carried out via an edge detection algorithm.
- the target zones Z c detected are, for example, of the same nature (example: only roofs).
- the target zones Z c can be of different natures (example: roofs and terraces).
- Figure 3 illustrates an example of an M_Zc zone mask obtained from an IM image.
- the determination method comprises a step 120 of applying the zone mask M_Zc to the image IM to obtain an image, called the target image IM_C, on which only the target zone(s) Zc of the image IM are represented .
- Step 120 is put into implemented by the computer 10 in interaction with the computer program product 12, that is to say is implemented by computer.
- the target image IM_C thus corresponds, for example, to the image IM with application of a continuous background (black for example) to the portions of the image IM different from the target zones Zc.
- the information and details of the target zones Zc are therefore kept on the target image IM_C.
- Figure 3 illustrates an example of a target image IM_C obtained from an image IM and a mask of zones M_Zc.
- the determination method comprises a step 130 of edge detection on the target image IM_C to obtain an edge mask M_C.
- Step 130 is implemented by the computer 10 in interaction with the computer program product 12, that is to say is implemented by computer.
- the obstacles O are indeed discontinuities on the surface of a target zone Zc.
- the edge detection step is, for example, performed by applying a Canny filter to the target image IM_C.
- the filter applied is another edge detection filter, such as for example a Prewitt or Sobel filter.
- Figure 3 illustrates an example of an M_C contour mask obtained from a target image IM_C.
- the determination method comprises a step 140 of highlighting obstacles O in each target zone Zc of the image IM by combining the zone mask M_Z C and the outline mask MC to obtain a mask of the obstacles O present on the or the target zones Zc of the image IM, called obstacle mask M_O.
- Step 140 is implemented by the computer 10 in interaction with the computer program product 12, that is to say is implemented by computer.
- the obstacle mask M_O thus corresponds to the zone mask M_Zc with superimposed, on the target zones Z c , detected contours materializing obstacles O (that is to say of the contour mask MC).
- Figure 3 illustrates an example of an obstacle mask M_O obtained from an area mask M_Zc and an outline mask M C.
- the determination method comprises a step 150 of determining an arrangement A of photovoltaic panels on each target zone Z c of the image IM as a function of the mask of obstacles MO so as to satisfy at least one positioning constraint.
- Step 150 is implemented by the computer 10 in interaction with the computer program product 12, that is to say is implemented by computer.
- At least one positioning constraint stipulates that each photovoltaic panel covers a portion of a target zone Zc devoid of obstacles O.
- the determination step 150 preferably comprises the extraction of image portions from the obstacle mask M O.
- the extracted image portions correspond to the target zones Zc.
- Each image portion has, for example, a predefined geometric shape, such as a rectangle shape.
- the dimensions of each image portion are for example chosen so that the image portion frames a target zone Zc.
- the contour mask MC is, for example, used to obtain the contours of the target zone Z c considered.
- the determination step includes the positioning of representative shapes of photovoltaic panels on the portions of images extracted from the obstacle mask M O.
- the representative shapes are, for example, rectangles.
- the positioning is, for example, carried out so that the shapes have the same orientation and are at a predetermined distance from the other shapes.
- at least one representative shape has a different orientation from the other shapes.
- the positioning is performed on portions of extracted images having the same orientation.
- the portions of images may have undergone a rotation before the positioning of shapes.
- the image portions are rectangles framing target zones Z c , the image portions are for example rotated so that the rectangles are vertical. This facilitates the arrangement of rectangles representative of photovoltaic panels on the portions of images.
- Figure 3 illustrates an example of a rotated portion of P1 images on which rectangles representative of photovoltaic panels have been superimposed.
- the shapes at least partially superimposed on an obstacle O are eliminated.
- the portion of images obtained following the elimination is called P2.
- the determined arrangement A of photovoltaic panels corresponds to the remaining shapes.
- the position and orientation of each shape corresponds to the position and orientation of a photovoltaic panel.
- a resulting image IM_R is obtained corresponding to the IM image of the territory superimposed on the target zone(s) Zc of the IM image of the arrangement A determined photovoltaic panels.
- the resulting IM_R image is shown in Figure 3.
- the resulting image IM_R is, for example, obtained from the portions of images on which the representative shapes of photovoltaic panels appear, and after a possible reverse rotation of these (when a rotation has been applied to these portions of images).
- the representative shapes are directly superimposed on the obstacle mask M O, without extracting portions of images.
- the arrangement A of photovoltaic panels is determined so as to satisfy at least one other positioning constraint chosen from the group consisting of:
- each photovoltaic panel is positioned on a portion of a target zone Zc corresponding to an irradiance greater than a predetermined irradiance over a given time period.
- a predetermined irradiance for example, an irradiance map corresponding to the territory studied is provided.
- the irradiance expressed in Watt per square meter (W/m 2 ) is the incident radiant flux (power) received by a surface per unit surface.
- the irradiance is, for example, determined by means of an irradiance map of the territory considered.
- each photovoltaic panel is positioned on a portion of a target zone Zc shaded by any obstacles O on at most a predetermined percentage of its surface over a given time period.
- information is provided relating to the parts of the target zone Z shaded over time.
- each photovoltaic panel is positioned on a target zone Z c so as to be at a distance greater than a predetermined minimum distance from any obstacles and/or from the contours of the target zone Z c .
- This constraint makes it possible, for example, to comply with health and safety rules (HSE rules).
- HSE rules health and safety rules
- a minimum distance of each photovoltaic panel is given from the edge of the roof, or from obstacles on the roof, such as chimneys or windows.
- the determination method comprises a step 160 of determining characteristics relating to the solar production of the determined arrangement A of photovoltaic panels.
- characteristics are, for example, the irradiance of arrangement A, the solar potential or the efficiency of arrangement A.
- Solar potential is the solar power received over an area in kilowatts per hour per year (kW/ h/year).
- Efficiency is the ratio between the energy produced (kWh) and the theoretical power (KWp) of an installation.
- the method comprises a step of designing an arrangement A of photovoltaic panels corresponding to the panels of the arrangement A determined, possibly followed by the effective positioning of the photovoltaic panels on the target zones Z c of the territory studied.
- the present method allows a more precise determination of the possibilities of installing photovoltaic panels on areas of a territory.
- such a method makes it possible to take into account obstacles that are incompatible with the effective installation of photovoltaic panels on the zones considered. The resulting panel arrangement is therefore more realistic.
