Solar Panel & Solar Farm
Drone Inspection Services in India

Thermal Precision

Radiometric thermal cameras detect sub-surface hot spots, PID effects, and bypass diode failures invisible to the naked eye — covering 1 MW in under 15 minutes.

10x Faster Than Manual

Inspect a 50 MW solar farm in a single day versus weeks of ground-based thermography. Minimal plant downtime, zero production loss during inspection.

Safety First

Eliminate the need for technicians to walk between panel rows in extreme heat. No scaffolding, no risk of arc flash from high-voltage DC strings.

AI-Powered Reports

Our proprietary AiServe platform auto-classifies defects by IEC 62446-3 severity, geo-tags every anomaly, and generates bankable inspection reports within 48 hours.

Dual-Sensor Capture

Simultaneous RGB and thermal imaging at 1 cm/px ground resolution ensures no defect is missed — from micro-cracks to soiling hotspots.

Hot Spots & Cell Overheating

Single-cell or multi-cell thermal anomalies indicating cracked cells, failed solder joints, or internal shunting — the most common failure mode in Indian solar plants.

Soiling & Dust Accumulation

Non-uniform soiling patterns causing localized heating and up to 25% energy loss. Especially critical in arid Gujarat, Rajasthan, and Tamil Nadu sites.

Bypass Diode Failures

Entire sub-strings appearing as hot rectangles in thermal imagery, indicating failed bypass diodes that can lead to permanent module damage.

PID (Potential Induced Degradation)

Systematic power loss across strings identified through characteristic thermal signatures at panel edges — detectable before IV-curve testing.

Micro-Cracks & Snail Trails

High-resolution RGB imaging at 0.5 cm/px reveals hairline fractures, snail trails, and delamination invisible during routine ground inspection.

Junction Box & Connector Faults

Thermal anomalies at junction boxes and MC4 connectors flagging loose connections, moisture ingress, or arcing risks before they become fire hazards.

String & Combiner Failures

Entire strings appearing uniformly cold in thermal imagery — an offline string is invisible from the ground yet is usually the single highest-value find in an inspection, because the lost generation is total rather than partial.

Tracker Misalignment

Row-level tilt and azimuth deviation measured from aerial imagery across single-axis tracker plants. Misaligned rows lose yield quietly and are difficult to spot on foot across hundreds of hectares.

Physical & Weather Damage

Glass breakage, frame deformation, delamination, burn marks and hail impact flagged from RGB imagery with GPS coordinates — the fastest way to scope a claim after a storm or hail event.

Bi-annual inspections, trend analysis, priority support

Gujarat

Charanka, Dholera, Kutch and Surendranagar. High dust loading off the Rann makes soiling analysis the priority here, and post-monsoon inspection catches mounting and water-ingress damage early. We are headquartered in Ahmedabad, so mobilisation across Gujarat is short.

Rajasthan

Bhadla, Jaisalmer, Jodhpur and Bikaner. India's best irradiance comes with extreme heat and abrasive dust, which accelerates cell degradation and hot-spot formation. Flights are planned around ambient temperature so thermal contrast stays valid at 45°C-plus.

Tamil Nadu

Kamuthi, Ramanathapuram and Tirunelveli. The northeast monsoon shifts the inspection window later than the rest of India, and coastal humidity raises the incidence of junction-box corrosion and connector faults.

Karnataka

Pavagada, Tumkur and Bellary. Many Karnataka sites sit in wind-solar hybrid parks, so flight planning has to account for turbine airspace and rotor wake alongside the panel array — a scheduling constraint pure solar sites do not have.

Madhya Pradesh

Rewa, Neemuch and Mandsaur. Central India's milder dust load shifts the priority from soiling toward module-level defects and string faults, which makes thermal contrast the deciding factor in scheduling rather than cleaning cycles.

Andhra Pradesh

Kurnool and Anantapur. Rapid capacity addition means a high share of plants are still inside warranty, so pre-commissioning and pre-warranty-expiry inspections carry the highest return here — defects found while the EPC or module supplier is still liable.

What weather conditions are needed for a valid thermal inspection?

Thermography needs irradiance above roughly 600 W/m², clear or lightly hazy skies, and low wind. Cloud cover flattens thermal contrast and makes defects unreadable, so flights are scheduled around regional weather and monsoon windows rather than to a fixed calendar date. In practice this means mid-morning to early afternoon on a clear day.

How accurate is defect localisation on a large plant?

Every defect is tagged with GPS coordinates and mapped to block, string and module position against your plant layout, so a maintenance crew is directed to a specific module rather than a general area. Accuracy depends on us receiving your as-built layout and string diagram before the flight — without them we can still map defects geographically, but not to string IDs.

Can you inspect rooftop and floating solar as well as ground-mount?

Yes. Rooftop C&I plants are flown at lower altitude with tighter flight lines and need airspace checks because they usually sit in urban areas. Floating solar requires additional safety planning for over-water operation and loss-of-link contingency. Both are routine, but they are planned differently from an open ground-mount site.

What do we actually receive at the end of an inspection?

An IEC 62446-3 aligned PDF report, a prioritised defect list as CSV or Excel, the underlying thermal and RGB imagery, a geo-referenced defect map overlaid on your plant layout, and access to the AiServe Solar dashboard. Formats are chosen so the output drops into your existing O&M workflow rather than sitting in a folder.

When is the best time in a plant lifecycle to inspect?

Three points give the highest return: pre-commissioning, before you accept the plant from the EPC and while defects are still their responsibility; immediately before warranty expiry, while module claims are still open; and post-monsoon, when soiling, water ingress and mounting damage are at their peak. Annual inspection is the practical minimum for an operating plant.

Do you need our string diagrams and plant layout in advance?

They are not mandatory, but they materially change the output. With the layout and string diagram we map every defect to a specific string and module ID. Without them you get accurate GPS-located defects but your team has to translate positions to asset IDs themselves, which is where most of the follow-up time goes.

How much does drone solar panel inspection cost in India?

Drone-based solar panel inspection costs ₹3,000–₹8,000 per MW for utility-scale solar farms. A typical 50 MW plant inspection costs ₹1.5–₹3 lakh including thermal + RGB flights, AI-powered defect analysis, and IEC 62446-3 compliant report. This is 60–80% cheaper than manual thermography at ₹15,000–₹25,000 per MW.

Can drones inspect solar panels while the plant is generating power?

Yes. Drone inspection is performed while the solar plant is fully operational with zero production loss. In fact, panels must be under load and irradiance (>500 W/m²) for thermal defects to be visible. We schedule flights during peak generation hours (10 AM – 2 PM) for optimal thermal contrast.

What defects can thermal drone inspection detect in solar panels?

Thermal drones detect hot spots, cell overheating, bypass diode failures, PID (Potential Induced Degradation), soiling patterns, micro-cracks (via RGB), snail trails, junction box faults, string failures, and vegetation shading. Our AI classifies each defect by IEC 62446-3 severity levels for priority-based maintenance.

How often should solar farms be inspected by drone?

Industry best practice recommends annual comprehensive drone inspection for all solar farms. High-value or warranty-claim sites benefit from bi-annual inspection (pre-monsoon and post-monsoon in India). Pre-commissioning inspection is recommended for all new installations before COD.

What is the difference between thermal and RGB drone inspection?

Thermal inspection uses radiometric infrared cameras to detect sub-surface defects like hot spots, bypass diode failures, and PID that are invisible to the eye. RGB inspection uses high-resolution cameras (48 MP) to identify surface defects like micro-cracks, snail trails, soiling, and physical damage. AiRotor Labs captures both simultaneously in a single flight for complete coverage.

Do you provide IEC-compliant inspection reports?

Yes. All AiRotor Labs solar inspection reports comply with IEC 62446-3 (outdoor infrared thermography of PV modules) and IEC TS 62446-3:2017 standards. Reports include geo-tagged defect maps, temperature delta analysis, severity classification, string-level heatmaps, and priority maintenance recommendations. Reports are accepted by all major Indian DISCOMs, SECI, and international lenders for performance audits.
