When a module fails and a solar panel warranty applies, the OEM asks for three things: the serial number, the installation location and test data that shows the defect. On most plants those records sit in different places, with serials in an EPC spreadsheet, commissioning IV and EL results in a handover folder and inspection photos in an O&M log. Solar warranty claims stall while someone rebuilds that history, and some slip past the OEM's notification deadline.
Digital documentation closes that gap by tying each defect to its serialized component, its location and its test data on one asset record. Owners, IPPs and O&M teams then start the warranty claim process with the evidence already in place, from the first thermal finding through replacement and re-inspection.
Solar warranty claims management is the process of identifying, documenting, filing and tracking claims against OEM warranties, from the first sign of a defect through to resolution.
A claim can fall under several warranties:
Product warranty: covers manufacturing defects in modules.
Performance (degradation) warranty: guarantees that module output stays above a defined level over time.
Workmanship/EPC warranty: covers the quality of the installation work.
Inverter warranty: covers inverter failures and component faults.
Tracker warranty: covers tracker mechanical and control components.
Each one has its own terms, notification deadlines and evidence requirements, so the record behind a claim has to be specific to the asset involved. In this article, we focus on PV module warranty claims, as these are the most common. Similar digital tools and workflows can be used for other components as well.
Testing data shows why claim-ready records matter from day one. In Kiwa PVEL's 2026 PV Module Reliability Scorecard, 87% of manufacturers experienced at least one failure during testing, and 45% had at least one major delamination failure among submitted modules. When a defect does show up in the field, five documentation gaps tend to slow a claim down or invite a rejection.
OEMs need the exact serial number and installation location to process a claim. Records kept by pallet or by block can get a project to the right area of the plant, and no further. Nothing in that chain shows where an individual module ended up.
Photos without IR, EL or IV data, or reports that don't follow IEC 62446-3, invite disputes. OEMs often reject claims when the IR data behind them is unreliable. Common thermal inspection mistakes, such as flying in poor irradiance or at the wrong altitude, can turn a valid solar panel inspection into evidence a manufacturer will dispute.
EPC spreadsheets, email threads and O&M logs rarely connect at handover. When a defect appears, the O&M team starts by searching for the history of the module before it can start building the claim.
Most manufacturers require defensible, standards-aligned evidence within a claim window. Slow evidence gathering pushes claims past notification deadlines.
Without commissioning records and baseline performance data, it can be difficult to establish when a defect emerged or to demonstrate how an asset's condition changed over time.
Evidence | What it proves | When it is captured |
|---|---|---|
Serial number and datasheet | The exact module and the specifications the warranty covers | At installation |
As-built map location | Where the module sits in the array (table, string, inverter) | At installation |
Commissioning baseline (IV, EL) | The module's condition at handover | During commissioning |
IEC 62446-3 thermal report | The anomaly type and severity, captured with a recognized method | Pre-COD baseline and periodic inspections |
Power-loss estimate | The performance impact of the defect | When the defect is detected |
Maintenance and SCADA history | How the asset was operated and when performance changed | Ongoing during O&M |
Geotagged photos | Field verification of the defect with time and location | During field inspection |
A commissioning baseline is the strongest proof that a defect developed after installation. Digital commissioning records store IV curves, EL images and thermal scans against each component, giving every solar panel warranty claim a clear "before" picture.
Manual documentation | Digital documentation | |
|---|---|---|
Traceability | Serials logged by pallet or block, with locations reconstructed later | Each serial number tied to its exact module position at installation |
Evidence quality | Photos and reports in separate files, often without IR, EL or IV data attached | Thermal, IV, EL and photo evidence linked to the same component |
Time to assemble a claim | Teams search folders, email and spreadsheets to rebuild the history | Evidence already attached to the asset and pulled from one record |
Audit trail | Depends on who logged what, and where | Time-stamped, geo-referenced records for each inspection and update |
EPC-to-O&M handover | Documentation compiled separately before handover | Construction and commissioning records carry into O&M with the asset |
Portfolio visibility | Claims and defects tracked site by site in separate files | Thermal risk and asset records visible across the portfolio |
Using PV module barcode scanning, crews record each module's serial number and its exact position in the array, which builds the foundation for warranty tracking across the asset's life. Scanning runs on handheld devices in the TaskMapper mobile app, and each serial is linked to its tracker and module position in the digital twin. Serial number records export as CSV for handover.
At commissioning, teams record IV curve traces, EL images and thermal scans and store them against the specific components they describe. Baseline IR scans before acceptance can reveal installation defects early. Each asset ends up with an as-commissioned record, which SenseHawk calls a Digital Birth Certificate. If a defect appears later, the team can compare current data with this baseline to show when the condition changed.
Periodic drone IR scans find hotspots, string faults and bypass diode failures across the plant. Each finding is classified, given an estimated temperature difference and power loss, and mapped to the module, string and inverter it belongs to. Capturing the scans in line with IEC 62446-3 keeps the evidence defensible, and our guide to drone-based IR analysis covers the workflow in more detail. Defects that may be covered under warranty then need further investigation in the field.
Technicians navigate to the exact defect location from a map in the mobile app and inspect the module. They capture photos with the in-app camera, which can stamp each image with the date, time and GPS coordinates, and add annotations and notes. Using the mobile app, the technicians can further classify and triage defects based on what is warrantable and what is not covered by the warranty agreements. The app works offline, and the data syncs when the connection returns.
Because serials, baseline data, thermal findings and field photos sit on the same asset record, the claim package comes together from one system. Therm generates IEC 62446-3 compliant reports automatically, and PDF exports let teams choose which raw drone images, attachments, notes and tasks to include. Serial number records export as CSV, and the commissioning baseline is already linked to the same component.
Therm tracks warranty claims end to end, so everyone can see where each one stands. Each defect carries a status, an assignee and a priority, from Pending through Verified and In Progress to Resolved. When the manufacturer supplies a replacement, the new serial number is scanned into the same position, which keeps the record current. A follow-up thermal inspection then confirms the fix.
Whether you are evaluating solar inspection software or a broader asset platform, these are the questions that matter for warranty work.
Can the system connect evidence to the exact module, string, inverter or other asset?
Can teams capture evidence directly from the field, with photos, notes and location attached to the right asset?
Can field teams collect information when connectivity is limited? Remote sites often have weak coverage.
Can thermal scans, IV curves, EL images and inspection results be connected to the asset?
Can finalized documents and records be organized without relying on scattered folders?
Can teams view documentation in the context of the actual solar plant?
Can teams quickly generate or export the evidence required for claims?
SenseHawk's TaskMapper platform connects each step above, so the serial number, baseline, inspection and photo evidence for a claim sit on the same asset record.
Barcodes (Step 1): crews scan PV module serial numbers with handheld devices in the TaskMapper mobile app. Each scan is tied to a tracker and module position in the digital twin and can be exported as CSV for handover.
Equipment Twin (every step): a connected asset model from module to substation that carries serial numbers, datasheets, warranties, IV curves, test results and maintenance history.
Commissioning (Step 2): IV curve and EL data are mapped to components, and every asset gets a Digital Birth Certificate, a record of its as-commissioned state that simplifies future warranty claims.
Therm (Steps 3 to 6): drone thermal analytics with AI classification, power-loss estimates, IEC 62446-3 reports and field remediation workflows, connected to the same asset record.
SenseHawk's AI-powered thermal inspection tool, Therm, classifies over 30 anomaly types and generates IEC 62446-3 compliant reports. Teams can then track each claim end to end, bringing detection and warranty claims management into one workflow. SenseHawk supports 200+ GW of solar and storage globally.

What documents are needed for a solar panel warranty claim?
Typically the module serial number and datasheet, its installation location, commissioning baseline data (IV and EL), a thermal inspection report that follows IEC 62446-3, a power-loss estimate, maintenance and SCADA history, and geotagged photos. Exact requirements vary by manufacturer and warranty terms, so check the warranty document and its notification requirements.
How long does a solar module warranty claim take?
Timelines vary by manufacturer, warranty terms and claim type, so no single duration applies. What teams control is how quickly they can assemble complete evidence. Claims with missing serials, baseline data or non-standard reports tend to go back and forth with the OEM, and claims backed by complete records give the manufacturer less to dispute.
Can thermal inspection reports support a warranty claim?
Yes, when the report follows IEC 62446-3, identifies the anomaly type and severity, and ties to the serialized module and its location. A thermal image on its own is harder to defend. Capture conditions such as irradiance, altitude and sensor settings also affect whether a manufacturer will accept the data.
What is warranty tracking software for solar assets?
Warranty tracking software links each component's serial number, warranty terms, test and inspection records, and open claims to its place in the plant. It lets teams see what is covered, document defects with evidence and follow each claim through to resolution.
Without commissioning records and baseline performance data, it can be difficult to establish when a defect emerged or to demonstrate how an asset's condition changed over time.
