What a Solar Developer Needs from a Land Survey
A solar project lives or dies on numbers that come out of the ground survey. If the boundary is wrong the pricing is wrong, and if the terrain is misread the panel layout has to be redrawn. At Yogeshwar Associates we survey solar sites across Pune, PCMC and wider Maharashtra, and here is what a developer actually needs from us.
Accurate boundary and area verification
Land is priced per acre and capacity is planned per usable acre, so the first job is to confirm exactly how much land there is and where it ends. We use Total Station and DGPS to fix corner coordinates to centimetre accuracy and reconcile them against the 7/12 and revenue records.
- Verified boundary with marked corners on the ground
- A confirmed area statement you can trust for per-acre costing
- Early flags on encroachment, road setbacks or shape that reduce usable land
Getting this right protects both the purchase price and the megawatt capacity you commit to. See our solar farm survey service for the full scope.
A topographic survey for layout, drainage and grading
Once the boundary is fixed, the design team needs to know the shape of the land. A topographic survey captures spot levels, contour lines and existing features so panel rows, drainage and grading can be planned properly.
- Contour mapping to plan panel-row orientation and spacing
- Natural drainage paths so water does not sit under the array
- Grading and cut-and-fill estimates before earthwork is priced
How slope and terrain affect shading and mounting
Slope is not just an earthwork problem — it changes energy yield. Rows on the wrong slope shade each other, and uneven ground drives up mounting and foundation cost.
- Slope direction and gradient that affect shading between rows
- Terrain data to size mounting structures and pile depths
- Cut-and-fill balance so you move the least earth for a workable plane
Drone and UAV survey to cover large sites quickly
Solar sites are large, and walking every point is slow. A drone or UAV survey captures thousands of measurements in a single flight, giving dense contour and surface data over hundreds of acres far faster than ground methods alone.
- Fast coverage of large or difficult plot terrain
- High-density surface model for accurate contour and volume work
- Photographic record of the site as it stood on survey day

A coordinate-referenced layout the EPC team can build on
The survey is only useful if the design team can build directly on it. We deliver a coordinate-referenced CAD dataset so your EPC design flows straight into layout and setting-out.
| Deliverable | Use for the design team |
|---|---|
| Boundary and area statement | Land pricing and capacity planning |
| Contour and topographic map | Panel rows, drainage, grading |
| Coordinate-referenced CAD | Layout design and stake-out |
| Drone orthophoto | Site context and verification |
Everything is tied to real-world coordinates, so what we survey and what the developer builds are the same thing on the ground.
