The Problem
Solar Construction Is Running on Outdated Information
India is commissioning gigawatts of solar capacity annually. Yet the monitoring of that construction across sprawling sites in Rajasthan, Gujarat, Andhra Pradesh, and Tamil Nadu still relies heavily on manual walks, WhatsApp photos from subcontractors, and periodic site visits that happen once a fortnight.
The gap between what your EPC contractor reports and what is actually on the ground can be weeks of progress or more accurately, weeks of missed progress.
👉 No Verified Progress Data Between Site Visits
Contractors self-report progress. Without aerial verification, billing milestones are settled on unverified claims often resulting in overpayments for work not yet done.
👉 Sites Are Too Large to Walk Systematically
A 100 MW solar site spans 250–300 acres. A ground team can cover perhaps 20 acres in a working day. Critical deviations in mounting structure alignment or module installation are missed entirely.
👉 As-Built Deviations Are Caught Too Late
When mounting structures go up misaligned or module rows are installed at the wrong tilt, corrections made after the fact cost 3–5× more than catching the issue during installation.
👉 Labour Deployment Is Invisible to Project Owners
Multi-vendor EPC contracts with dozens of subcontractors create persistent visibility gaps on actual manpower deployment making it impossible to hold anyone accountable for slow zones.
The Service
What Is Drone Solar Project Progress Monitoring?
Drone-based solar project progress monitoring is a scheduled aerial data collection and analytics service — specifically designed for the construction phase of utility-scale, C&I, and ground-mount solar projects in India.
Unlike solar panel inspection (which identifies faults in operating plants) or rooftop surveys (which assess feasibility before installation), this service tracks the live construction status of your solar site row by row, zone by zone against your planned timeline and design.
DGCA-certified drone pilots fly your site on a schedule you define. The resulting aerial data is processed into orthomosaic maps, progress percentage overlays, deviation reports, and structured dashboards — delivered to your project management team within 48 hours of each flight.
- Module installation progress tracked at row and string level
- Mounting structure alignment checked against approved drawings
- Earthwork and civil completion verified with volumetric data
- AI-assisted worker and machinery count per zone
- Cable tray and stringing progress documentation
- Time-stamped records for lender reporting and insurance
How Drone Solar Project Progress Monitoring Works
Site Assessment & Monitoring Plan
Our team reviews your solar project layout, EPC contract milestones, and reporting obligations. We define flight paths, monitoring zones, data deliverables, and the schedule aligned to your construction programme, not a generic template.
Scheduled Drone Flights by DGCA-Certified Pilots
Trained pilots deploy to your site on a fixed cadence — weekly, bi-weekly, or milestone-based. Every flight follows an automated, pre-programmed route using RTK-GPS drones, ensuring consistent coverage and georeferenced data every single time.
Data Capture — RGB, Thermal, LiDAR (as required)
High-resolution RGB imagery is the foundation for orthomosaic mapping and progress tracking. Optional thermal imaging flags structural anomalies. LiDAR is available for earthwork volumetric analysis and terrain modelling on large sites.
AI Analytics — Module Count, Labour, Deviation Detection
Captured data is processed through AI-assisted analytics to count installed modules by zone, identify deployed workers and machinery, and overlay actual installation against your approved design to flag structural deviations above threshold.
Report Delivery — Dashboard, PDF, Exportable Formats
Structured progress reports and dashboard access are delivered within 48 hours of each flight. Reports include progress percentage by zone, deviation summary, labour and equipment data, and comparison against previous flight. Formats: PDF, GeoTIFF, Excel-compatible data, and dashboard link.
Why Solar EPCs and IPPs Choose Drone Monitoring
✦ Complete Site Visibility Without Being There
Monitor a 500-acre solar site from your office in Bengaluru, Mumbai, or Delhi — with the same level of detail as a physical site walk, delivered to your screen within 48 hours.
✦ Verified Contractor Progress, Not Self-Reported
Replace EPC contractor self-reporting with aerial-verified data on module installation, mounting completion, and civil status giving you objective grounds for milestone billing approval or dispute.
✦ Early Deviation Detection Saves Rework Costs
Mounting structure misalignment caught at Week 2 costs hours to correct. The same deviation caught at Week 8 — after stringing and cabling costs days. Drone monitoring closes that gap.
✦ Objective Labour & Equipment Deployment Data
AI-assisted counting of deployed workers and machinery per zone helps project managers validate contractor labour claims, identify under-resourced zones, and improve schedule recovery planning.
✦ Lender-Ready Progress Documentation
Geo-tagged, time-stamped aerial reports provide the construction progress evidence required by lenders, insurance underwriters, and project finance teams reducing delays in drawdown approvals.
✦ Faster Decision-Making Across Multi-Vendor Sites
When 8 subcontractors are working simultaneously across different zones, drone monitoring provides the unified site view that no single on-ground supervisor can provide enabling faster escalation and resource reallocation.
Solar Monitoring Across Segments & States
From 1 MW rooftop C&I projects in Chennai to 500 MW utility-scale parks in Rajasthan, Lesoko’s solar construction monitoring adapts to your project type and pace.
Utility-Scale Ground-Mount Solar Construction
Large solar parks — 50 MW to 1,000 MW — are where drone monitoring delivers the most dramatic ROI. The sheer scale of these sites makes comprehensive manual inspection practically impossible during active construction.
Lesoko monitors these projects at zone level, tracking mounting structure erection, module installation row-by-row, cable tray and inverter installation progress, and comparing each flight’s data against the approved construction schedule.
- Weekly or bi-weekly flight schedules during peak construction
- Zone-wise progress percentage reported per contractor
- Mounting alignment deviation flagged for immediate correction
- Labour deployment data per zone per flight
Commercial & Industrial Rooftop Solar
For C&I installers and EPCs handling multiple rooftop projects simultaneously across cities, drone monitoring provides rapid, low-cost progress verification without the logistical cost of sending a site engineer to every installation.
A single drone deployment can cover 5–8 rooftop sites in a city in one day — replacing 5–8 separate site visits with higher-quality photographic documentation than ground teams typically produce.
- Multi-site progress verification in a single deployment day
- Installation completeness documented for billing and handover
- Roof structure status compared across project portfolio
- Before/after documentation for commissioning records
Hybrid Solar + Storage & Floating Solar
Hybrid projects combining solar PV with battery storage, wind, or pumped hydro introduce additional monitoring complexity — multiple contractors, phased timelines, and interconnected civil and electrical works across a single site boundary.
Floating solar projects on reservoirs in Kerala, Odisha, and Maharashtra present unique access challenges that make ground inspection impractical — and drone monitoring the only viable regular option.
- Phased monitoring across solar, storage, and civil packages
- Floating solar pontoon and module installation tracking
- Multi-contractor coordination through unified reporting
- Specialist access for reservoir and canal-top solar sites
EPC Contractors — Internal Quality & Progress Control
Leading EPC contractors use Lesoko’s monitoring service not just for client reporting — but for their own internal progress control, sub-contractor accountability, and early detection of civil or installation deviations that could trigger liquidated damages.
A weekly drone flight gives the EPC project manager an independent verification layer above subcontractor self-reporting — essential when schedule slippage has direct financial consequences under the contract.
- Independent verification of subcontractor progress claims
- Early deviation detection before client or lender site visit
- Labour and equipment utilisation data for resource planning
- White-label reporting for client-facing progress presentations

Frequently Asked Questions
These are two distinct services for different phases of a solar project. Drone solar panel inspection is an O&M service for commissioned, operating plants — it uses thermal and RGB cameras to detect hotspots, bypass diode failures, and cell-level defects in live panels. Solar project progress monitoring is a construction-phase service — it tracks how many modules have been installed, verifies contractor progress against your schedule, and identifies mounting or civil deviations before they cause rework. Both use drones, but the flight parameters, analytics, and deliverables are entirely different. If your plant is under construction, you need progress monitoring. If it is generating power, you need inspection.
Yes — commercial drone operations are fully legal in India under the Unmanned Aircraft System (UAS) Rules, 2021, issued by the Ministry of Civil Aviation. All commercial drone pilots must hold a DGCA Remote Pilot Certificate (RPC). Lesoko operates entirely within this regulatory framework — every pilot on every Lesoko mission holds a valid DGCA RPC, and all flights are conducted in compliance with applicable airspace rules. For sites near restricted zones such as airports or military installations, appropriate airspace permissions are obtained during the mission planning phase, before any flight is conducted.
Yes — AI-assisted analysis of drone orthomosaics can count installed solar modules by zone and row with high accuracy, compare the actual count against the planned installation schedule, and flag zones where installation pace is falling behind. For a 100 MW project with over 400,000 modules across 250+ acres, this level of visibility is simply not achievable by any ground team. The module count data is delivered zone-by-zone in each progress report, giving project owners objective verification of contractor claims without requiring a single physical site visit.
RTK-GPS drones deployed with proper Ground Control Points (GCPs) achieve horizontal positional accuracy of 2–5 cm. This is more than sufficient for detecting solar mounting structure misalignment, row spacing deviations, module tilt angle variations, and pile placement offsets relative to approved engineering drawings. Deviations beyond a configurable threshold are automatically flagged in each monitoring report with GPS coordinates, deviation magnitude, and a recommended corrective action — giving your engineering team precise, actionable information to act on before the next construction phase begins.
Monitoring frequency should match your construction pace and risk exposure. During peak structural and module installation phases, weekly drone flights provide the most actionable data — deviations are caught within days, not weeks. For milestone-based lender or insurance reporting, bi-weekly flights are typically sufficient. During slower phases such as cable laying, stringing, and pre-commissioning checks, monthly monitoring is often adequate. Lesoko designs monitoring schedules around your specific construction programme — not a generic template — so you only pay for the frequency your project genuinely requires.
Yes. Lesoko has active operational experience across India’s most remote and challenging solar project environments — desert-terrain sites in Rajasthan, coastal projects in Andhra Pradesh and Tamil Nadu, arid sites in Gujarat, and elevated terrain in the Northeast. Our distributed pilot network allows rapid mobilisation to remote locations without the logistical delays that affect providers who rely on centralised teams. Any applicable accessibility surcharge for remote sites is calculated transparently and included in your project quote before engagement begins.
Standard deliverables include a geo-referenced orthomosaic map (GeoTIFF), high-resolution RGB imagery, zone-wise progress percentage breakdown, deviation summary with flagged GPS locations, and a structured PDF progress report formatted for internal review or direct lender submission — all delivered within 48 hours. Monthly monitoring clients additionally receive dashboard access with full flight history, trend analysis across monitoring periods, and exportable data. AI analytics packages include module count by zone, labour and machinery deployment count, and as-built vs. planned design overlay analysis.
Yes — this is one of the highest-value applications of drone-based solar construction monitoring. Lesoko’s reports are time-stamped, GPS-georeferenced, and include full flight metadata — meeting the construction progress evidence requirements of most project finance lenders and independent engineers operating in the Indian solar market. For insurance underwriters, the visual record provides objective, dated evidence of physical site condition and construction quality at any milestone point. This significantly reduces the time and cost of preparing drawdown documentation packages compared to manual site visit reports.
Drone monitoring provides EPC contractors with an objective, aerial-verified layer above subcontractor self-reporting — which is essential when liquidated damages clauses and milestone payment triggers are in play. Lesoko configures the monitoring framework directly against your EPC contract milestones, so each report maps to specific payment events. This gives project managers documented grounds to approve or dispute subcontractor billing claims, identify under-performing zones early enough to recover schedule, and present clients with credible third-party verified progress data at every review meeting.
Manual site visits have three fundamental limitations for utility-scale solar construction. First, coverage: a ground team can inspect roughly 15–20 acres per day — a single drone flight covers 300+ acres in hours. Second, objectivity: a site engineer walking a 250-acre project can only sample what they physically see; a drone captures every row, every zone, every section in a single consistent pass. Third, frequency: the cost and logistics of sending a senior engineer to a remote Rajasthan or Andhra Pradesh site every week is prohibitive — drone monitoring makes weekly aerial verification economically viable for every project. The result is a monitoring programme that is simultaneously more comprehensive, more frequent, more objective, and less expensive than an equivalent manual visit schedule.
