Abstract

Claims (46)

1 . A method of determining usable area of a structure for solar energy production, the method comprising:

obtaining a three-dimensional model of a structure and obstructions associated therewith; and

performing a shading analysis using the obtained three-dimensional model to obtain a usable area of the structure.

2 . The method of claim 1 , further comprising calculating a solar energy potential for the structure based on the obtained usable area.

3 . The method of claim 1 , wherein obtaining the three-dimensional model comprises obtaining three-dimensional data from stereo photography.

4 . The method of claim 1 , wherein performing the shading analysis comprises performing a time series analysis with a plurality of snapshot images of the structure and obstructions for a corresponding plurality of sun positions.

5 . The method of claim 4 , wherein performing the shading analysis further comprises determining usable area on a per pixel basis.

6 . The method of claim 5 , wherein performing the time series analysis comprises, for each pixel in each snapshot image, determining whether the pixel receives sunlight.

7 . The method of claim 6 , wherein performing the time series analysis further comprises, at least for each pixel that receives sunlight, determining a total number of images in which the pixel receives sunlight.

8 . The method of claim 7 , wherein performing the shading analysis further comprises:

at least for each pixel that receives sunlight, comparing the total number to a threshold value;

determining a number of pixels for which the total number exceeds the threshold; and

determining the usable area based on the determined number of pixels.

9 . A method of providing solar information for a structure using a Web portal, the method comprising:

providing an interactive map;

receiving a user selection of a structure located on the interactive map; and

providing solar information for the selected structure, wherein the solar information is based at least in part on a usable area obtained by performing a shading analysis using a three-dimensional model of the structure and obstructions associated therewith.

10 . The method of claim 9 , wherein the solar information provided comprises at least one of solar energy potential, electricity production potential, economic savings potential, electricity savings potential, and amount of potential reduction in carbon dioxide production for the selected structure.

17 . A system for providing an interactive Web portal, the system comprising:

a database including solar information regarding at least one structure; and

a server configured to provide a Web portal including an interactive map to a client device, configured to receive a selection of the at least one structure located on the interactive map from the client device, configured to access the database to retrieve the solar information regarding the at least one structure based on the selection of the at least one structure, and configured to provide the retrieved solar information to the client device.

18 . The system of claim 17 , wherein the server is configured to receive the selection as an address input by a user of the client device.

19 . The system of claim 17 , wherein the solar information included in the database is based at least in part on a usable area obtained by performing a shading analysis using a three-dimensional model of the structure and obstructions associated therewith.

20 . The system of claim 17 , wherein the solar information included in the database comprises a usable area obtained by performing a shading analysis using a three-dimensional model of the structure and obstructions associated therewith.

21 . The system of claim 20 , wherein the server is configured to calculate solar information regarding the at least one structure based at least in part on the usable area retrieved from the database and to provide the calculated solar information to the client device.

22 . A method of solar mapping using a Web portal, the method comprising:

providing an interactive map;

receiving a user selection of a location on the interactive map; and

providing an estimate of at least one of solar energy potential, economic savings potential, electricity savings potential, and amount of potential reduction in carbon dioxide production for the selected location.

23 . The method of claim 22 , wherein receiving a user selection comprises receiving an address input by a user.

24 . The method of claim 23 , further comprising displaying a location of at least one existing solar installation.
