Catch anomalies while they are small.
In a single flight, every panel in your plant is imaged with a thermal camera from dozens of angles and measured on an AI-assisted processing pipeline. The type, priority and estimated annual production loss are determined for each finding. Monitoring systems cannot provide this, because they measure at inverter or string level. Panel-level losses can go unnoticed inside those totals for years.
Anomalies detected early can be resolved before they grow, which prevents the loss from extending over years.
FLIGHT
How the digital twin is built
The route covers the whole site
The route is planned over the site boundary with lines crossing the panel rows, and it covers the whole plant in a single flight. A flight altitude of 30 m gives the resolution IEC TS 62446-3 requires.
01
The frames from the flight are stitched into one map
The frames from the flight are stitched into a single map covering the whole plant. The location and identity of each panel on the site are determined from this map.
02
The whole plant is shown in a single thermal map
The thermal map is aligned on the same pixel grid as the visible-light map, so temperature differences can be read directly on the map.
03
AI detects the panels
Image segmentation detects the modules in the plant one by one. Each module's outline is recorded together with its row, table, tier and column position.
04
Measurement flags the anomalies
Each module's temperature difference, normalised to irradiance, is compared with the neighbouring panels, and panels that show a clear deviation are flagged.

05
Model names the anomaly type
A classification model assigns each finding to one of the 17 anomaly classes and gives it a priority.
ΔT · normalised to irradiance · K

- 5+16.1 K · MULTIPLE DIODES ×2
- 6+15.6 K · DIODE ×2
The finding's location on the orthomosaic
A finding is verified when it measures consistently across several frames that see the same module from different angles.
The same module, examined in the drone's raw frames at full resolution
06
A separate page is prepared for every finding
The page holds the finding's position, its RGB and thermal close-ups, its class, the number of modules affected and its estimated annual loss. Every finding is verified across several images.
07
The report is prepared after the flight
After the flight, an inspection report is prepared and the same findings are added to your panel record on the platform. Because every inspection is recorded against the same panel identities, a temperature history is built for each panel. We recommend one inspection a year.
Platform modules
What you manage on the platform
Every step of the maintenance process, from detection to resolution, is managed on one platform. The SolarDetech platform gives every panel in your solar power plant a persistent identity and updates the panel record with every flight. All of the modules below work on that same record.
Portfolio management
The fleet map, last inspection dates, open findings and priority breakdown of all your plants are shown on one screen.
Panel-level digital twin
Each panel's persistent identity, geographic position (block, row, table), electrical position (transformer, inverter, combiner, string) and measurement history are kept. The record is updated with every flight.
Autonomous thermal inspection
The inspection provides 100% panel coverage. Every panel in the plant is imaged, measured with a thermal camera and recorded under its persistent identity. Orthomosaic, panel segmentation and anomaly detection run without human intervention. The model assigns each anomaly to one of 17 classes, and an expert confirms the class.
Work and maintenance management
Every anomaly is listed with its probable root cause. A work order opened from a finding is assigned, tracked and closed. The field team is guided on the map to the relevant panel. The panel's status is tracked from anomaly to repair, and a resolved anomaly is closed on the same record at the next inspection.
Serial number records
Each panel's serial number is entered into its record by scanning the label with a camera (OCR) and can be corrected manually if needed. For warranty claims and panel replacements, the serial number is available together with the panel's position and measurement history.
Inventory management
Panels, inverters and combiner boxes are kept in one inventory with their serial numbers and positions. Spare parts and stock levels are tracked. The history of replaced parts is kept on the record.
Warranty claims
The serial number, measurement history and raw frames are gathered into one claim file. The verification process with the manufacturer is managed on the platform.
Production loss and efficiency
The estimated production loss of every anomaly is calculated. Plant efficiency is tracked by period and by anomaly group.
Performance and trends
The yield and findings of the plants in a portfolio are monitored comparatively. The degradation trend and the estimated loss for the coming period are calculated from the panel history.
Fire risk
Junction box heating, string faults with arc traces and advanced hot spots can carry fire risk. These anomalies go to the top of the list with very high priority.
History and comparison
Measurements of the same panel from different inspections are displayed side by side. This allows comparison after a storm, before and after a warranty claim, and between consecutive flights.
Measurement conditions
The irradiance and weather of every flight are recorded and documented in the report.
Teams and roles
Teams are defined per plant, with separate roles for the field team, the operator and the investor.
Integration
An API is available for partners. You can add your own users to plant teams and create one-click sign-in links for them.

Comparison of methodsEvery finding in the report has a known basis
The same three rules apply to every inspection. No figure appears in the report without a stated source, and findings based on a single frame are not included.
ROWS · ΔT Based on measurement
A panel is not counted as anomalous unless it shows a measurable temperature difference from its neighbours. Measurements are normalised to irradiance.
SAME MODULE, SEPARATE FRAME Verified across many images
Every panel is assessed from many images taken from different angles. A finding is included in the report only when it is measured consistently in more than one image.
REPORT · FINDING PAGE Every finding has a recorded source
For every finding in the report, the image and measurement it is based on are recorded. Where needed, the panel's temperature data can be examined down to pixel level.

StandardsCommon questions about solar thermal inspection
All eighteen questions and their answersWhat is SolarDetech?
The SolarDetech platform is a panel-level digital twin and asset management platform for solar plants. Its thermal inspection is fully autonomous.
The platform's modules all work on the same record: portfolio management, a panel-level digital twin, autonomous thermal inspection, work and maintenance management, serial number records, inventory management, warranty claims, production loss and efficiency, fire risk, history and comparison, measurement conditions, teams and roles, integration. In the thermal inspection, the orthomosaic, the panel segmentation and the anomaly detection are produced from thermal and RGB drone data without human intervention. The model assigns each anomaly one of 17 classes. An expert confirms the class of every anomaly in the report. Findings are shown on the map, ordered by priority and converted into work orders. The platform is free. The inspection is priced by quote for your site. The flight is carried out by our professional field team or by your own team with a drone that has RTK and a radiometric thermal camera. Measurement and classification are carried out in line with the IEC TS 62446-3 methodology.
What is a digital twin, and what does it cover on the SolarDetech platform?
On the SolarDetech platform the digital twin is panel-level. Every panel in your plant keeps its persistent identity, its position and its measurement history in one record.
Each panel is assigned a persistent identity that does not change from flight to flight. Its geographic position is recorded as block, row and table, and its electrical position as transformer, inverter, combiner and string. The measurement of every flight is added to the same panel identity, which builds the panel's measurement history. The digital twin is this record, updated with every flight. Findings, work orders and close-outs are linked to it. When a finding is opened, the panel's location on the map and the inverter and string it is connected to are shown on the same screen. Whether an anomaly has grown, and whether it has closed after repair, is also tracked on this record.
What is solar thermal inspection and how is it done?
Every panel in your plant is measured with a thermal camera, and every anomaly detected is listed with its type and location.
A drone with thermal and RGB cameras images the whole site from an altitude of 30 m in a single flight. The frames are stitched into a single map, and AI detects the panels one by one. Each panel's temperature difference is normalised to irradiance and compared with the neighbouring panels, and panels that show a clear deviation are flagged. The anomaly type of each flagged panel is determined by a classification model, and every finding is verified across several images. At the end of the inspection a report is delivered and the findings are added to your panel record on the platform. For every anomaly the report gives the row, table and panel, its type, its priority and its estimated annual loss. Flight, measurement, classification and reporting are carried out in line with the IEC TS 62446-3 methodology.
Is the platform free?
Yes, the platform is free. Only the inspection is charged.
There is no charge for platform access, and only the inspection is charged. The inspection is priced by quote for your site. The quote arrives within 24 hours at most. The report and the platform record are included in the inspection. If you have a drone with RTK and a thermal camera, your own team can carry out the flight. Your panel record, your map and your earlier inspections are kept on the platform.
How is the price calculated?
Every plant gets its own quote. The quote arrives within 24 hours at most.
The platform is free. The inspection is priced by quote for your site. The quote is prepared from the plant's panel count and location. Classified and prioritised findings, the inspection report and the platform record are included in the inspection. If our field team carries out the flight, the number of flight days is also stated in the quote. If you have a drone with RTK and a thermal camera, your own team can carry out the flight. To receive a quote, you only need to provide the panel count and the plant's province. The quote arrives within 24 hours at most. By the industry average, a plant loses 5.77% of its production a year, and most of this loss is concentrated in a small number of high-priority findings. This is why a prioritised report matters.
Which provinces do you cover?
Our field team carries out flights across Türkiye on ground-mounted and rooftop plants. For plants abroad, the platform can be used by uploading the data.
We work at sites in all provinces, particularly Konya, Karaman, Şanlıurfa, Ankara, Kayseri and Niğde, where installed capacity is concentrated. The number of flight days depends on the size of the site and is stated in the quote. If you have an RTK-equipped drone with a thermal camera, your own team can also carry out the flight. Data from plants abroad is processed as well. In that case the flight is carried out by your own team, and the data is uploaded through the link we send after approval. In every case the data is collected to the same standard and passes the same acceptance check.
Every panel measured, every anomaly verified.
