One of the most common questions we get from solar plant owners and O&M managers is: "How much does drone inspection cost?" The honest answer is — it depends. But in this guide we break down every factor that affects pricing so you can budget accurately and avoid overpaying.
What Factors Affect Solar Inspection Cost in India?
- Plant size (MW capacity) — larger plants have lower per-MW cost
- Location — remote sites with poor road access add mobilisation cost
- Inspection type — thermal only vs EL + IV curve testing
- Report standard — IEC 62446-3 compliant vs basic report
- Turnaround time — standard 48h vs expedited 24h delivery
- State — Gujarat and Rajasthan have high competition, lower prices vs Northeast
- Access conditions — flat ground vs mountainous terrain
Typical Price Ranges for Drone Solar Inspection in India
| Plant Size | Thermal Only | Thermal + EL | Thermal + EL + IV Curve |
|---|---|---|---|
| Up to 1 MW | ₹18,000–₹35,000 | ₹40,000–₹70,000 | ₹65,000–₹1,20,000 |
| 1–5 MW | ₹25,000–₹60,000 | ₹60,000–₹1,20,000 | ₹90,000–₹1,80,000 |
| 5–20 MW | ₹50,000–₹1,20,000 | ₹1,00,000–₹2,50,000 | ₹1,50,000–₹3,50,000 |
| 20–100 MW | ₹80,000–₹3,00,000 | ₹2,00,000–₹5,00,000 | ₹3,00,000–₹8,00,000 |
| 100+ MW | Custom quote | Custom quote | Custom quote |

What is Included in the Price?
- Drone mobilisation and demobilisation to site
- DGCA-compliant flight operations with certified pilots
- Thermal image capture of 100% of modules
- Data processing and fault detection analysis
- GPS-tagged fault report with thermal images
- IEC 62446-3:2022 compliant PDF report
- Severity classification (Critical / Moderate / Low)
- Corrective action recommendations
- 48-hour delivery from survey completion
How to Reduce Your Solar Inspection Cost
- Sign an Annual Maintenance Contract (AMC) — discount of 15–25% vs one-time inspection
- Bundle multiple plants in the same region in one mobilisation
- Schedule during off-peak season (monsoon planning, winter months)
- Opt for thermal-only inspection for routine annual audits — add EL only when needed
- Provide accurate plant layout and layout DXF files to reduce site survey time
Is Drone Inspection Worth the Cost?
A typical 10 MW solar plant generates ₹4–6 crore of revenue per year. Hotspots, soiling, and string faults routinely cause 3–8% generation loss — that is ₹12–48 lakh in lost revenue per year. A drone inspection costs ₹50,000–₹1,20,000. The ROI of finding and fixing even one critical fault is immediate and significant.
Frequently Asked Questions
Do you charge extra for remote locations in Rajasthan or Gujarat?
For plants more than 100 km from Ahmedabad, we add a mobilisation charge based on actual travel distance. This is quoted upfront — no surprises.
Can I get an AMC for drone inspection?
Yes. Our AMC packages cover annual, bi-annual, or quarterly inspections with priority scheduling and 15–25% discount on standard rates.
Do you offer a sample report before I commit?
Yes. Contact us at hemal@varunaat.in and we will send a sample IEC 62446-3 compliant inspection report so you can evaluate quality before booking.
