Advanced Thermal Imaging for Roof & Panel Inspections

Protect Your Solar Investment from the Ground Up with Advanced Thermal Imaging

Investing in solar power is a smart move for sustainability and long-term savings. But what about the foundation supporting your solar panels? A compromised roof can undermine your entire investment, leading to costly repairs and system downtime. That’s why we offer comprehensive thermal imaging services, ensuring your solar project is built on a solid foundation.

Common Roof Defects We Identify

  • Trapped moisture within flat roof insulation
  • Failed waterproof membranes
  • Delamination in built‑up roofing systems
  • Ponding water and poor drainage areas
  • Thermal bridging and insulation gaps
  • Mechanical damage and punctures
  • Degraded flashing and edge details
  • Early‑stage leaks invisible to the naked eye

Outcome: A clear, evidence‑based condition report allowing repairs to be completed before solar installation, protecting warranties and long‑term ROI.

Solar Panel Thermal Imaging Inspections (Drone‑Based)

Once installed, solar panels must operate efficiently to deliver expected financial returns. Our aerial thermal inspections quickly scan entire solar arrays with minimal disruption.

Defects We Detect in Solar PV Systems

  • Hot spots caused by cell damage or manufacturing faults
  • Micro‑cracks and broken cells
  • Faulty bypass diodes
  • String failures and disconnected modules
  • Soiling and shading losses
  • PID (Potential Induced Degradation)
  • Junction box overheating
  • Cable and connector faults
  • Inverter‑related thermal anomalies

 

Preventing Fire Risk with Thermal Imaging

Thermal imaging acts as an early-warning system for solar safety by detecting “hot spots”—localised areas of high resistance caused by cracked cells, faulty wiring, or failing bypass diodes.

Since these electrical defects generate significant heat before they ever become visible to the naked eye, thermography allows you to:

  • Prevent Arcing: Identify loose connections and failing junction boxes that could spark a fire.
  • Stop Thermal Runaway: Catch overheating cells before they melt the panel’s backsheet or surrounding roofing material.
  • Actionable Maintenance: Transition from reactive repairs to proactive prevention, ensuring the system stays within safe operating temperatures.

In short, thermal scanning transforms invisible electrical stress into a clear visual map, allowing you to neutralise fire hazards before they ignite.

STAGE-1

PRE-SOLAR INSTALLATION ROOF ASSESSMENT: UNVEILING HIDDEN ISSUES

“Imagine the cost and headache of removing your entire solar array for roof repairs! We help you avoid this”

Before a single solar panel is installed, we deploy our state-of-the-art, high-resolution thermal imaging drone. This advanced technology allows us to conduct a thorough visual and infrared (IR) inspection of your roof. We meticulously analyse the data to identify:

Compromised Roof Membranes:

Saturated areas and hidden weaknesses that could lead to future leaks.

Waterproofing Defects:

Early detection of potential water intrusion points, preventing costly damage.

Structural Integrity:

A comprehensive overview of your roof’s condition, ensuring it can handle the weight and installation process.

WHY DO WE USE THERMOGRAPHY:

Simply put, is shows us what the naked eye can’t see. During the daytime, any moisture that has penetrated the roof system will heat up. After sunset, the surrounding areas that are dry, will cool down quickly whilst the water will retain its heat and start to radiate. The method shows up clearly the areas of roof that are holding water to assist in leak tracking to the penetration points for general saturation analysis.

We always recommend follow up core samples are taken to confirm diagnosis.

STAGE-2

PHOTOGRAMMETRY WITH AREAS OF SATURATION MEASURED.

Standards & Compliance

ANOMALY TYPES AND ANOMALY REVIEW

The efficient operation and longevity of solar energy systems require regular monitoring and maintenance. In this process, the detection of various anomalies that may occur in solar panels plays a critical role. Anomalies can reduce the efficiency of solar panels and lead to losses in energy production. MapperX is an advanced software that detects these anomalies using thermal and RGB photographs with the support of artificial intelligence.

Cell Anomaly:

Cell anomalies in solar panels cause inefficiency or failure. Thermal imaging detects temperature differences, highlighting performance issues.

Multi-Cell Anomaly:

Multiple cell anomalies are failures across several cells, often due to connection issues or defects. Thermal inspection reveals overheating, which can significantly reduce panel energy production.

Diode Problems:

Diodes in solar panels allow current flow in one direction. Thermal images show overheating when diodes fail, causing energy production losses by hindering panel efficiency.

Multi-Diode Problems:

Diodes in solar panels allow current flow in one direction. Thermal images show overheating when diodes fail, causing energy production losses by hindering panel efficiency.

Service Overview

Thermal Imaging Defect Analysis allows you to Act on Independent Advice – Not on What a Contractor Wants to Sell You
Whether making repairs or refurbishments your decision should be based on facts –
Visual Perspectives uses the latest infra-red technology to accurately measure areas of moisture, leaks and energy loss without mess, disruption or scaffolding.
The thermal images provide hard data – free from the assumption or bias that you risk with a traditional building survey.

Commercial Building Envelope Assessments

Surveying commercial properties quickly and cost effectively can be a challenge. Most are in continual operation meaning access to certain areas can be problematic. A Thermographic Survey can be the perfect solution to determine any regions of weakness in the waterproofing and insulation of a commercial property. Thermal surveying is a form of non-destructive testing (NDT) and can therefore be carried out without any risk to health and safety, staff, or equipment.

This is an economic targeted approach to locate defected areas quickly, visually and can be used as a guide to save time and money when a more intrusive inspection is instructed.

Is your facility running too hot?

Electrical inspections can often be slow and only carried out during downtime or when a failure occurs. Many insurance companies now insist on an annual thermal inspection for compliance. Visual Perspectives can provide a cost-effective solution whereby we provide a suitable report and information to allow electricians and engineers to carry out repairs.

Companies who practice infrared predictive maintenance regularly check the temperature of critical equipment, allowing them to track operating conditions over time and quickly identify unusual readings for further inspection.

Integrating thermography into your maintenance schedule

By monitoring equipment performance and scheduling maintenance when needed, we can reduce the likelihood of unplanned downtime due to equipment failure, spend less on “reactive” maintenance fees and equipment repair costs, extend the lifespan of machine assets, and further maximise maintenance and production.

Heat is often an early symptom of equipment damage or malfunction, making it a key performance parameter monitored in predictive maintenance programmes.

Infrared thermography cameras are the first line of defence in a predictive maintenance program.

Visual Perspectives can quickly measure and compare heat signatures for each piece of equipment on the inspection route, without disrupting operations.

Need to safely and quickly check the condition of a roof? We can help.

Surveying a roof conventionally using platforms or cherry pickers can be costly and a breach of the working at height regulations. The modern method of roof inspection utilises drones, which can provide exceptional data that you need from ground level.

Visual Perspectives work alongside building surveyors to undertake detailed surveys and provide high quality photos, videos, and reports. Our drone operators are certified to CAA regulations and carry £5 million insurance to put your mind at rest.

With over 1,500 surveying assignments under our belt, including thermal imaging, topographical surveys3D scans and models, and more, you can trust our team to pay attention to every detail of your project.

What Are The Benefits Of Using Drones For Roof Inspections Compared To Traditional Methods?

While traditional roof inspection methods have been the standard for many years, drones are becoming a more efficient, safe, cost-effective, and accurate option for rooftop inspections. Some of the benefits of utilising inspection drones are listed below.

Visual Perspectives Drone Surveys provide a safe and efficient way to inspect rooftops, reducing the need for scaffolding, rope access, or other equipment associated with traditional methods that can be costly and time-consuming to set up.

As a result, Visual Perspectives Drone Surveys eliminate the need for people to be on the roof or work from elevated roof platforms, which can be dangerous…and instead access the data they need with their feet firmly on the ground.

Visual Perspectives Drone Surveys provide access to areas of a roof that would otherwise be difficult or impossible to reach with traditional methods, such as steep pitches or high elevations, or features such as skylights and chimneys.

This enables our inspectors to conduct a more robust and thorough search.

Visual Perspectives Drone Surveys can conduct a roof inspection quickly, reducing the time it takes to complete a job. They can cover a large area in a shorter amount of time than traditional methods and are much quicker than erecting scaffolding or scaling the building using rope access to conduct a manual inspection.

Visual Perspectives Drone Surveys can save time and money by providing a more efficient and accurate assessment of the roof’s condition. They can also reduce the need for scaffolding or other equipment, which can be costly and time-consuming to set up.

Visual Perspectives Drone Surveys can quickly and easily capture high-resolution images and videos, allowing for detailed inspections of the roof and its components.

This can provide a more accurate and detailed assessment of the roof’s condition, and also offer a different and more complete perspective of the roof in one wide-angle shot.

For instance, this high-res image shows areas of this roof which have been damaged in a storm. This sort of record is beneficial for assessing the extent of the repairs and for submitting insurance claims.

Drone Site and Building Mapping

The Technique

Thanks to greater accuracy in drone navigation systems, computing performance and onboard photographic sensors, aerial photogrammetry by drone is highly performant and enables precision drone mapping, whatever the size and configuration of the terrain.

Easier and cheaper than using imagery from a manned aircraft, drone photogrammetry provides professional-grade material for aerial surveys and inspections, enabling centimeter precision scaling, and measurement of distances, surface areas, and volumes.

Drone mapping from photogrammetry also allows us to easily create 3D models that can be rotated over 360 degrees on all axis to achieve a unique point of view of the photographed buildings, artwork, structures, quarries, bridges, roads, etc…

​Visual Perspectives frequently uses aerial photogrammetry to gain higher zooming capabilities for surveyors in need of high-precision imaging of the inspected assets. Many industry sectors are using drone photogrammetry, such as:

  • Construction
  • Agriculture
  • Landscaping
  • Roofing
  • Insurance claims
  • Solar
  • Mining
  • Energy
  • Telecommunications

2D Drone Mapping Survey

To get a high-definition aerial picture of the area, allowing us to zoom in to cm scale details, we fly the drone at a low altitude (40m in the example below) following a pre-defined path, taking automatically pictures of the zone. This is the definition of photogrammetry. The application then reconstructs the whole area, providing an ultra-high resolution scalable picture available in GeoTIFF, jpeg, and pdf, las, xyz, dxf/shp, obj, rcp.
