Abstract

A system for deploying solar panels may include a classification module configured to receive an image of a structure with a roof and to classify portions of the image that include portions of the roof as roof image segments. The system may also include an identification module configured to identify a property of the roof based at least in part on the roof image segments and a configuration module configured to determine a configuration of one or more solar panels for placement on the roof based on the identified property of the roof.

First claim

What is claimed is:

1. A computer-implemented method of determining solar panel deployment configurations, the method comprising:
receiving, at one or more processors, an image with a plurality of structures with roofs;
receiving, at the one or more processors, a map corresponding to the image, the map including indications of parcels of land;
segmenting, by the one or more processors, the image into a plurality of land segments that correspond with the parcels of land in the map;
estimating, by the one or more processors, expected power generation for each of the plurality of land segments, wherein estimating the expected power generation for a first of the plurality of land segments includes:
segmenting the first of the plurality of the land segments into a plurality of image segments;
classifying the plurality of image segments that include portions of a roof as roof image segments;
identifying a property of the roof based at least in part on the roof image segments;
determining a configuration of one or more solar panels for placement on the roof based on the identified property of the roof; and
estimating the expected power generation of the first of the plurality of land segments based on the configuration of the one or more solar panels; and

estimating, by the one or more processors, a cost of the placement of the solar panels in each of the plurality of land segments based on the estimating the expected power generation.

2. The method of claim 1 , wherein the classifying the image segments as the roof image segments is performed based on a color of the image segments or a texture of the image segments.

3. The method of claim 1 , wherein the determining the configuration of the one or more solar panels is further based on one or more of: an orientation of the one or more solar panels, a number of the one or more solar panels, shading of the roof, weather factors, electricity usage of a structure that includes the roof, time dependent electricity rates, and a tilt angle of the one or more solar panels.

4. The method of claim 1 , wherein the property of the roof comprises a footprint of the roof, a slope angle of the roof, an orientation of the roof, or a height of the roof.

5. The method of claim 4 , wherein the property of the roof comprises the footprint of the roof, the method further comprises:
grouping the roof image segments into a polygon; and
smoothing detected edges of the polygon to form the footprint of the roof.

6. The method of claim 4 , wherein the property of the roof comprises the slope angle of the roof, the method further comprises:
receiving a street view image of at least one of the plurality of structures;
isolating the at least one of the plurality of structures within the street view image;
automatically identifying walls of the at least one of the plurality of structures;
automatically identifying a high point of the at least one of the plurality of structures;
automatically identifying a wall high point of at least one of the walls; and
automatically identifying an angle between a horizontal and a line between the high point of the at least one of the plurality of structures and the wall high point of the wall.

7. The method of claim 1 , further comprising managing power generation of the one or more solar panels based on the expected power generation.

8. A processor configured to execute computer instructions to cause a system to perform operations for solar panel deployment, the operations comprising:
automatically identifying properties of at least one roof of a plurality of structures of a region based at least in part on an image of the plurality of structures without input from a user;
determining a configuration of one or more solar panels for placement on the at least one roof of the plurality of structures based on the identified properties of the at least one roof;
estimating expected electricity generation of the one or more solar panels based on the configuration of the one or more solar panels;
estimating a first cost of deploying the one or more solar panels on the at least one roof of the plurality of structures within the region; and
estimating a second cost of deploying solar panels for a plurality of regions including the region.

9. The processor of claim 8 , wherein the operations further comprise managing electricity generation of the one or more solar panels based on the expected electricity generation under one or more conditions.

10. The processor of claim 8 , wherein the operations further comprise ranking each of the plurality of regions based on the estimated second cost for each of the plurality of regions.

11. The processor of claim 8 , wherein automatically identifying the properties of the at least one roof comprises the operations of:
receiving the image of the plurality of structures with the at least one roof;
segmenting the image into a plurality of image segments;
classifying the plurality of image segments including portions of the at least one roof as roof image segments; and
automatically identifying the properties of the at least one roof, based at least in part on the roof image segments, without input from the user.

12. The processor of claim 8 , wherein the determining the configuration of the one or more solar panels is further based on one or more of: an orientation of the one or more solar panels, a number of the one or more solar panels, shading of the at least one roof, weather factors, electricity usage of a structure that includes the at least one roof, time dependent electricity rates, and a tilt angle of the one or more solar panels.

13. The processor of claim 8 , wherein the properties of the roof comprises a slope angle of the roof and automatically identifying the slope angle of the roof is based on a determined slope angle of a second roof of a second structure.
