Surveying the site before designing the system
A sound photovoltaic project starts with accurate site measurements: elevations, slopes, obstacles, and interference. A drone survey integrated with ground-based measurements provides a precise terrain model—even over large areas and in the presence of vegetation—in a fraction of the time it takes for a traditional survey. We conduct the survey and provide the results to the designers, so that the layout is based on real data rather than estimates.
What is it used for, in detail?
The survey data are directly incorporated into the design and evaluation of the site. Specifically, they are used for the following purposes.
Terrain Model
Actual elevations and slopes for positioning structures and trackers and for determining the size of excavations. This is the foundation on which a layout truly stands, rather than having to adapt to surprises on the job site.
Interference and Shading
The heights of buildings, trees, and power lines can be queried in the model to prevent production losses. Unanticipated shading results in costs throughout the plant’s entire lifespan.
Obstacles and Constraints
Boundaries, obstacle heights, and site features that affect the layout—these are things you need to know before setting up the project, not once work has already begun.
Construction Site Logistics
Access points, traffic flow, and work areas are assessed before the construction site opens, so that the work plan is based on actual data.
Useful Return
3D models, 2D drawings, contour lines, or georeferenced site plans—in whatever format the designer needs—even long after the fact and without having to return to the site.
When needed
Topographic surveying is useful in three common situations.
Greenfield development
To bring a project to the "ready-to-build" stage based on reliable metrics.
Agrivoltaics and Roofing
To identify farmland or rooftops where the system can be evaluated.
Review of a Proposed Project
To verify that the layout provided by a third party works with the site's actual data.
Based on our findings
How We Work
We agree with the client on the necessary level of detail, prepare the drone survey—supplemented where necessary with ground-based measurements—and deliver the results in a format suitable for design. The data remains the property of the client and is used for their project.
