Why Ground Mount Solar Projects Fail Before Installation Starts
Inaccurate site data is the root cause of every preventable cost overrun in solar construction. These four problems compound through the project lifecycle and every one of them begins before a single panel is installed.
👉 Wrong Terrain Data = Wrong Layout
Fixed-grid Total Station surveys miss micro-elevation changes and slope variations. These errors surface as rework during civil work after earthmoving equipment has already been mobilised and costs committed.
- Cost impact: 20–35% earthwork overrun
👉 Missed Vegetation Causes Shadow Losses
Manual surveys cannot accurately count and map existing trees and shrubs. Unaccounted vegetation causes shading losses of 10–25% that run across the plant’s entire 25-year generation lifespan.
- Cost impact: 10–25% generation loss
1-Month Surveys Delay Project Timelines
Traditional DGPS/Total Station surveys require 10,000+ data points for 1,000 acres and take approximately one month. This delay costs project approvals, financing windows, and competitive bid timelines.
Earthwork Errors Inflate Civil Costs
Without precise Bund Cut/Fill Volume data, civil contractors quote conservatively inflating earthwork estimates by 20–35%. Exact drone volume calculations eliminate this contingency padding entirely.
About the Service
What Is a Ground Mount Solar Survey?
A ground mount solar survey is a drone-based aerial data acquisition service using RTK-GPS equipped UAVs to capture precise terrain data of a proposed solar installation site generating every map, model, and measurement your engineers need to design and build a ground-mounted solar power plant accurately.

Why Ground Mount Solar Survey Is the First Step Every Solar Project Needs
Skipping a ground mount solar survey or relying on outdated satellite imagery is the single most common reason solar projects run over budget. Without accurate terrain data, your EPC contractor is designing a solar array on assumptions. Pile depths are guessed. Earthwork volumes are padded.
Row spacing is calculated without knowing the actual slope. Every one of these gaps compounds into a cost that arrives on site, not on paper. A drone-based ground mount solar survey eliminates all of them before your project moves past the planning stage giving every downstream decision a foundation of real data.
A precise drone-based ground mount solar survey delivers the exact data your engineers need for accurate solar plant layout design calculating inter-row spacing based on real terrain slope data, optimising ground coverage ratio (GCR) to maximise panel density on every acre, and generating PVsyst-compatible terrain exports for bankable solar feasibility study and energy yield modelling.
Unlike satellite imagery or manual DGPS data, drone-captured DEM gives your shadow analysis calculations a real-world terrain foundation not an approximated flat surface. This means your PVsyst simulation reflects actual site conditions. Delivering energy yield estimates that financiers, lenders, and DISCOM teams accept without revision.
For solar EPC contractors conducting pre-construction solar survey work, and for project developers preparing detailed project reports (DPRs) for DISCOM connectivity applications, a Lesoko solar topographic survey provides every map, model, and measurement in a single engagement removing the need for multiple survey vendors at different project stages.
What Our Clients Say
“Lesoko’s drone survey for our ground mount site in Tamil Nadu was delivered in 3 days. The topolayout and contour maps were exactly what our structural team needed far superior to the DGPS survey we used on our previous project.”

Frequently Asked Questions
A ground mount solar survey is a drone-based technical assessment of a proposed land site to determine its suitability for a ground-mounted solar power plant. Using RTK-GPS equipped UAVs, the survey captures high-resolution aerial data processed into Orthomap, Topolayout, DEM, Contour Maps, Vegetation Index, Slope Percentage, and Bund Cut/Fill Volume calculations all at sub-1cm accuracy.
Lesoko delivers complete end-to-end ground mount solar survey reports within 4 working days for sites up to 1,000 acres. 60 times faster than traditional DGPS surveys, which take approximately one month for equivalent data. For urgent pre-feasibility checks, expedited turnaround is available on request.
A 1 MW ground-mounted solar plant typically requires 4 to 5 acres with fixed-tilt mounting structures, or 5 to 6 acres when single-axis trackers are used. The exact requirement depends on panel wattage, inter-row spacing determined by shadow analysis, terrain slope, and state DISCOM setback norms — all of which Lesoko’s survey resolves accurately.
Lesoko achieves less than 1cm level accuracy in all drone-based ground mount solar surveys using RTK-GPS equipped UAVs. Unlike Total Station surveys which lock grid accuracy at a fixed value, drone surveys allow fully adjustable grid accuracy 5m×5m, 1m×1m, or any variable. Making outputs significantly more useful for solar layout design and earthwork planning.
Lesoko’s ground mount solar survey report includes: Georeferenced Orthomap, Topolayout Map, Digital Elevation Model (DEM), Contour Map at 0.1m or 0.5m or 1.0m intervals, Contour Map with Spot Levels at 5m×5m or 10m×10m grid, Slope Percentage Map, Vegetation Index with tree and bush counts, Bund Cut/Fill Volume calculations, Point Cloud data, and Handheld Camera Site Images. All deliverables are available in KMZ/KML, AutoCAD DWG, and GeoTIFF formats — compatible with PVsyst, AutoCAD, and GIS platforms.
NDVI (Normalised Difference Vegetation Index) in a ground mount solar survey is AI-powered analysis delivering exact tree, bush, and shrub counts across the proposed solar site. It is critical for shadow modelling to prevent 10–25% generation losses, accurate land clearance cost estimation, and compensation assessment for land acquisition.
Yes. Lesoko Technologies is headquartered at T. Nagar, Chennai, Tamil Nadu, and deploys DGCA-certified survey teams across all of India. We have completed ground mount solar surveys and inspections in Tamil Nadu, Andhra Pradesh, Rajasthan, Gujarat, Maharashtra, West Bengal, Bihar, Karnataka, Telangana, Madhya Pradesh, and Kerala. Lesoko is empanelled with WBREDA, BREDA, and MEDA government bodies and has delivered surveys for EPC companies including L&T, Sunedison, Enerparc, and Sterling and Wilson across multiple states.
A Topolayout map is a topographic layout map overlaying precise elevation and terrain data onto the georeferenced orthoimage of the solar site. It enables design engineers to plan row orientation, inter-row spacing, and mounting structure design using actual terrain contours — not the approximated flat surface assumptions that DGPS data produces.
Drone survey is 60 times faster, requires fewer than 200 control points versus 10,000+ for DGPS, delivers adjustable grid accuracy, includes AI-powered vegetation analysis with exact tree and bush counts, provides precise Bund Cut/Fill Volume calculations, and covers terrain physically inaccessible for ground crews including dense forests, steep slopes, and water bodies.
