Thermal Documentation
Solar PV Thermal Documentation
Document apparent temperature patterns across a photovoltaic array and preserve corresponding RGB and location context for later review.
- Location
- Greater San Antonio, TX
- Setting
- Exterior photovoltaic array
- Capture type
- Aerial thermal and RGB
- Outputs
- Thermal imagery, RGB context, location notes
- Asset
- Photovoltaic array
Objective
Documentation objective
Record apparent surface-temperature differences across the array and keep the corresponding visual and location context so maintenance or inspection teams could review specific modules rather than walking the field without a map.
Methods
Capture method
Thermal and RGB stills were captured together so apparent temperature patterns could be located on physical modules. Coverage was planned for module-level review of the array.
Aerial thermal work for this project used a radiometric thermal sensor paired with a high-resolution RGB camera. Equipment is a method, not the service.
Deliverables
What was delivered
- Thermal imagery
- RGB imagery
- Annotated snapshots with location context
- Mapped array context
- Review report organizing documented patterns
Documented observations
Apparent temperature patterns
Thermal color is a visualization of apparent temperature. The patterns below were documented for later review. They are not independent determinations of module failure or liability.
Localized high-temperature cells
Apparent hotspots were recorded so specific modules could be inspected later.
Repeated block patterns
Multi-cell temperature patterns were documented as areas identified for further electrical review.
String-level variation
Uneven heating along a string was recorded with location context for downstream review.
RGB confirmation
Thermal frames were reviewed against visual imagery to locate the pattern on the physical array.
Thermal imaging records apparent surface-temperature differences. Interpretation of those patterns, including any determination of defect cause, remains with qualified personnel.
Technical considerations
The deliverable pairs apparent temperature patterns with RGB frames and location context. It does not, by itself, determine module failure, string faults, or a maintenance priority. Qualified review is required before any operational conclusion.
