Our site footprints give more precise data (where available) about the area covered by each solar power plant. For established projects this is obtained from satellite imagery. Otherwise, and for projects in development, it may come from site plans, photographs or planning submissions.
In general, the site area shown is all that is enclosed within any perimeter fencing for the project. Rooftop projects indicate the outline of the roofs on which they solar arrays are mounted. Unfenced ground mounted projects show the area of the solar arrays plus a surrounding border, to allow for the area are likely to be required for maintenance access.
Where plants are directly connected to transmission stations, these are included within the indicated area if they fall within, or are directly adjoining to, the site boundary.
Because we typically show the entire fenced area, some projects may have a larger footprint than is strictly necessary for the solar generating station; for example if fencing is taken around ponds or woodland within the project area.
All of the maps in this website are displayed using cartography and satellite images from Google Maps.
Google regularly updates its satellite images, but the frequency with which this happens varies in different parts of the world. There may be some instances where solar generation stations have been in existence for several years but still do not appear on the satellite images.
Wiki-Solar's aim is to show site footprints of all projects on our Database for which they are available. .
We also show some other plants, such as:
where these are geographically close to utility scale solar projects in the Wiki-Solar Database.
Because Google Maps uses different images at different magnification levels you may sometimes need to zoom in or zoom out to see the solar project on the map.
Some site footprints have been captured from satellite images from providers other than Google. These may not yet appear on Google Maps, but probably will if you return in a few months time.
Some projects may be captured during the construction stage, and you may need to return later to see the completed installation.
