How long does a solar site survey take?

A rooftop feasibility assessment typically takes 3-5 working days from site data receipt. Ground-mount topographic surveys for MW-scale sites depend on land size and access but generally take 1-2 weeks including report preparation.

Do you need a physical site visit, or can this be done remotely?

Where a physical visit isn't feasible (international projects, tight timelines), we can conduct a preliminary desktop feasibility assessment using satellite imagery, available drawings, and client-supplied photos/drone footage, followed by a physical verification step before final design sign-off.

What happens if the feasibility study finds the site isn't viable as planned?

We flag the specific constraint (structural, shading, land, or grid) and provide alternative recommendations — reduced capacity, alternate layout, or design modifications — so you have a clear path forward rather than a dead end.

Is site survey included in your Detailed Engineering Design service, or is it separate?

It's available as a standalone service or bundled with Detailed Engineering Design. We recommend running it first on any project where site conditions are uncertain, since it directly shapes the DED scope and cost.

Solar Site Survey &
Feasibility Services

Every solar project's accuracy starts before a single drawing is made it starts with knowing exactly what the site can and can't support. Solyug Energy's site survey and feasibility services give EPCs and developers a clear, data-backed picture of land or roof viability before committing engineering hours to a design that might not work on the ground.

Preventing On-Site Structural Rework & Capacity Derating

A design built on assumptions about land contours, soil bearing capacity, roof structural condition, or shading obstructions is a design that gets revised expensively during execution. We've seen projects lose weeks to structural rework because a rooftop's load-bearing capacity wasn't verified upfront, or lose generation capacity because a nearby obstruction wasn't accounted for in the layout. A proper feasibility study removes that risk before it becomes a cost.

Verified site survey measurements feed directly into our Detailed Engineering Design and 3D Shadow Analysis workflows, ensuring zero discrepancy between ground reality and final installation blueprints.

Execution Workflow

Our Site Survey Process

Our solar rooftop 3D modeling process moves through four stages, from raw site data to a client-ready presentation file.

Stage 01

Data Collection

Site photos, available land/roof drawings, and where possible a physical or drone-based site visit.

Topographic & Land Survey (Ground-Mount) For MW-scale ground-mounted projects, we assess land topography, soil type indicators, drainage patterns, access road feasibility, and boundary/area verification against available land records. This directly informs your row-spacing, cut-and-fill requirements, and foundation design decisions before detailed engineering begins.

Rooftop Structural Feasibility (Rooftop/C&I) For rooftop and C&I projects, we assess existing structural condition, available load-bearing capacity, roof type and slope, available mounting area after accounting for existing rooftop equipment, and access for installation and maintenance.

Shading & Obstruction Assessment We identify near-shading (parapets, HVAC units, adjacent structures) and far-shading (trees, neighboring buildings, terrain) obstructions using sun-path analysis, giving you real generation-loss estimates before layout finalization — not after installation.

Grid Connectivity & Evacuation Feasibility For larger projects, we assess proximity to substations, likely evacuation voltage level, and any preliminary grid-connectivity constraints that could affect project sizing or phasing.
