Thermal inspection and cleaning of solar PV installations
Visual and thermal capture, anomaly location and planned specialist cleaning for industrial rooftops, commercial installations and solar parks.
Where we work
- Industrial rooftops
- Commercial installations
- Solar parks
- Asset portfolios managed by maintenance companies
Inspection
We carry out a visual and thermal capture of the installation to locate the areas that need attention.
- Visual and thermal capture
- Identification of thermal anomalies and possible hotspots
- Location of areas to check
- Documentation to guide maintenance
Certified thermography
Reports are prepared by a thermographer holding the international ITC (Infrared Training Center) Level 1 certification. We go beyond capturing thermal data: we analyse the radiometry of every image to document anomalies with technical rigour, in a format that is useful for maintenance providers and insurers.
- Qualification: ITC Certified Thermographer, Level 1
- Inspection to the international standard IEC 62446-3
- Radiometric analysis and detection of hot spots in cells
- Performance audits of PV installations
Why output drops
Soiling builds up gradually and is often not visible from the ground.
- Dust and dirt
- Pollen
- Bird droppings
- Salts and pollution residue
- Biofilm
Specialist cleaning
Each cleaning job is planned around the actual condition of the installation.
- Assessment of soiling and access
- Planning around the installation, materials and surroundings
- Choice of a method compatible with the asset
- Documentation of the work
- Regular follow-up as needed
What it gives you
- Makes faults easier to detect
- Helps prioritise maintenance work
- Documents the condition of the modules
- Supports maintenance decisions
- No need to go up onto the roof
Frequently asked questions
Can inspection and cleaning be combined?
Yes, where the installation allows it. An inspection beforehand helps document the condition of the modules and plan the cleaning, and one afterwards allows a comparison.
Can thermal imaging tell us the exact cause of any fault?
No. Thermal imaging shows temperature differences that may indicate an anomaly. These need to be interpreted and, where appropriate, followed up with further checks to determine the cause.
What do we receive after an inspection?
The material and reports agreed in the proposal: for example, visual and thermal images, the location of areas to check and observations to guide maintenance. Deliverables are defined for each service.

The location, type of roof or park and approximate size are enough for us to start assessing it.
