Harnessing the Power of Thermal Drone Technology for 100MW Solar Farm Surveys

As solar energy capacity continues to grow across the UK and beyond, the need for reliable, accurate, and efficient inspection methods has never been greater. At Impact Aerial, we have been at the forefront of delivering cutting-edge drone surveys for some of the largest solar farms in the country.

One of the most powerful tools in our arsenal is the DJI Matrice M30T Thermal drone, a state-of-the-art aerial platform that allows us to carry out high-resolution thermal surveys across sites of up to 100MW capacity.

Why Thermal Surveys Are Critical for Solar Farms

Solar farms are vast, often spanning hundreds of acres and comprising tens of thousands of panels. Even a small percentage of underperforming or faulty panels can translate into significant financial losses.

Traditional ground-based inspections are slow, labour-intensive, and often limited in scope. By contrast, thermal drone surveys allow us to rapidly detect:

  • Hot spots caused by faulty cells or diodes
  • String failures and wiring issues
  • Soiling and shading effects
  • Inverter malfunctions

With the M30T’s powerful thermal imaging payload, we can scan entire solar farms in record time, ensuring that faults are identified quickly and remedial work can be prioritised.

The Power of the DJI Matrice M30T

The DJI Matrice M30T is built for tough industrial operations. Equipped with a high-resolution thermal camera, laser rangefinder, and 48MP visual sensor, it delivers both the detail and accuracy required for professional solar inspections.

Some of the key advantages we rely on include:

  • Long flight endurance – enabling extensive coverage per battery cycle.
  • Thermal and RGB imaging – allowing us to cross-reference hot spots with visual anomalies.
  • Weather resistance – crucial when surveying exposed solar farms in the UK’s unpredictable climate.
  • Compact yet powerful design – easy to transport but robust enough for industrial workloads.

Staying Powered in the Field – Up to 20 Drone Charges Per Day

One of the unique challenges of operating on large-scale solar farm projects is the sheer volume of flights required. A 100MW site demands multiple sorties, often over long hours.

To meet this demand, we deploy our DJI power banks, allowing us to recharge up to 20 drone batteries per day while on-site. This mobile charging solution ensures zero downtime, keeping our operations efficient and allowing us to complete surveys on tight deadlines.

By managing our energy supply in the field, we can maintain consistent productivity without relying on local infrastructure, which is often unavailable in the remote countryside locations where many solar farms are built.

Accessing Remote Solar Farms – Our Land Rover Discovery 4

Many of the solar farms we inspect are located in extremely remote areas, accessible only via muddy tracks and unpaved roads. To overcome this logistical challenge, our Land Rover Discovery 4 is an essential part of the team.

The Discovery’s off-road capability allows us to reach sites that would otherwise be inaccessible, carrying not only our drone fleet and charging systems but also the safety equipment and tools required for field operations.

This combination of airborne technology and rugged ground support means we can operate effectively in all conditions, from summer heatwaves to winter storms.

Delivering Value to Solar Farm Operators

By combining cutting-edge drone technology with practical field logistics, we provide our clients with:

  • Rapid, cost-effective inspections of even the largest solar farms.
  • Accurate, actionable data presented in thermal maps and detailed reports.
  • Minimised downtime and losses, helping operators maximise energy output.

For solar farms up to 100MW in capacity, our approach ensures that every panel is accounted for, every anomaly is detected, and every report provides clear insight for ongoing asset management.

Final Thoughts

At Impact Aerial, we believe that the future of solar farm operations lies in the marriage of advanced drone technology, reliable field support, and data-driven insights.

The DJI Matrice M30T Thermal drone, supported by our mobile charging solutions and rugged field vehicles, enables us to deliver industry-leading solar inspections, no matter how challenging the location.

As the renewable energy sector continues to expand, we remain committed to ensuring that solar farms operate at peak efficiency, delivering clean power to communities across the UK.

Harnessing the DJI Mavic 3 Thermal for Solar Farm Surveys in the UK

By Impact Aerial – Professional Drone Inspection Services

The UK solar industry has seen tremendous growth over the past decade, with solar farms now generating a significant portion of the nation’s renewable energy. For operators and asset managers, maintaining peak efficiency across large-scale installations—sometimes spanning hundreds of acres—is essential.

One of the most effective tools for ensuring operational performance is the thermal survey, and the DJI Mavic 3 Thermal has quickly become a go-to choice for inspecting solar farms up to 20 MW in capacity.

In this article, we explore why thermal inspections are crucial, how the Mavic 3 Thermal transforms the process, and what makes it the perfect fit for UK-based solar farm operators.

Why Conduct Thermal Surveys on Solar Farms?

Solar panels are designed to convert sunlight into electricity, but like any piece of technology, they can degrade or develop faults over time. Even minor defects can lead to reduced energy yield and unnecessary revenue loss.

Thermal surveys identify:

Hotspots – Areas of abnormal heat indicating defective cells, bypass diode failure, or connection issues.

Cracked or Delaminated Panels – Thermal patterns can reveal physical damage invisible to the naked eye.

Soiling or Shading Problems – Dirt build-up, bird droppings, or nearby vegetation causing efficiency loss.

Faulty Strings or Inverters – Large sections producing less output due to equipment failure.

Early detection means repairs can be made quickly, keeping generation levels high and avoiding further damage.

Why the DJI Mavic 3 Thermal Is a Game-Changer

The DJI Mavic 3 Thermal combines cutting-edge imaging with portability, speed, and safety—perfect for large-scale inspections in the UK’s variable weather conditions.

1. High-Resolution Thermal Imaging

The Mavic 3T features a 640×512 px thermal camera with a 61° field of view, capable of detecting small temperature differences. This allows inspectors to pinpoint faults on individual panels from a safe flight altitude.

2. Simultaneous Visual and Thermal Data

The drone’s dual-camera system captures thermal imagery alongside high-resolution visual images. This helps correlate anomalies with visible defects, streamlining fault verification.

3. Fast Coverage of Large Areas

With a flight time of up to 45 minutes per battery, the Mavic 3T can efficiently cover solar farms up to 20 MW in size—often in a single session—reducing downtime and site disruption.

4. Precision GPS & Mapping

Using RTK (Real-Time Kinematic) positioning, flights can be precisely planned and repeated for future inspections, enabling accurate year-on-year performance comparison.

5. Safe & Compliant Operations

The Mavic 3T is compact, quiet, and C2-certified for UK drone regulations, making it suitable for operations in proximity to infrastructure while adhering to Civil Aviation Authority (CAA) rules.
