Identify and record defective panels across your solar asset

A damaged panel or cell within a solar panel will show a temperature differential compared to the surrounding solar panels or cells.

Using thermography it is possible to see and record these anomalies, and using thermographic technology mounted on an Unmanned Aerial Vehicle (UAV), it is possible to accurately record these anomalies across vast areas of solar panels.

Going beyond string level monitoring

Your typical solar PV monitoring system will provide accurate plant performance information down to the string level. However, even if you have this, it does not provide the full picture, and proactively pinpointing specific subtle defects can be very difficult.

Our aerial thermographic survey enables us to identify subtle changes to your solar asset right down to the cell level and across your entire plant. The survey report will give you and your key stakeholders a comprehensive visual image of the solar asset health, enabling you to act promptly and directly to resolve defects and ensure optimum performance.


Prior to carrying out any aerial work time is spent to ensure the layout of the solar asset is accurately georeferenced. We also use our own custom software to create the optimal GPS Waypoint controlled flight route for your specific solar asset. This part of the process is key to ensuring that our SolarGain service delivers high quality and accurate results as well as the capability to precisely repeat the survey in the future.


We use the very latest in thermographic and photographic imaging technology as well as market leading UAV platforms. This ensures that we capture the highest levels of image resolution and data accuracy. Real time irradiance data is logged throughout the entire inspection process using our bespoke G.A.P (Patent Pending) technology to enhance the value of the imagery collected and assist in the analysis phase.


Post inspection data processing is carried out by our trained analysts who accurately locate each identifiable defect and cross reference these defects with visual imagery and the collected ambient data. This process utilises specialist software to assess the nature and significance of the defect as well as ensure the accuracy, consistency and data integrity throughout.


A comprehensive SolarGain asset health report is produced showing each identified Anomaly, together with the captured geo referenced imagery and associated data. This rich report is delivered via our own portal and is accessible through any internet connected device. Features of the SolarGain reporting portal include a dashboard, zoomable map, filtering, anomaly mark-up and csv export, enabling you to derive true value from the inspection results.

Module defects cause power loss and will worsen over time. Our experience shows that asset managers are unaware of the amount of defects that lie undetected in their solar farms.
Our SolarGain service will protect your investment.
