Undetected PV Defects Become Revenue Loss
Solar assets degrade quietly. Hotspots, disconnected strings, damaged modules, diode failures, soiling irregularities, and thermal anomalies reduce yield long before they are visible in standard monitoring dashboards. SkyPlotter identifies these issues quickly using structured aerial thermography and engineering-ready reporting, helping operators prioritize corrective action before underperformance compounds into lost revenue.
Hidden Hotspots & Cell Damage
Thermal anomalies at the cell and substring level that reduce module output without triggering inverter-level alarms.
String & Module-Level Anomalies
Bypass diode failures, PID degradation, and connection defects that compound across strings and reduce array performance.
Delayed Maintenance Prioritization
Without structured defect data, O&M teams lack the severity-ranked information needed to allocate resources efficiently.
Warranty & Documentation Gaps
Missing or incomplete inspection records weaken warranty claims and insurance documentation.
Performance Loss Starts Before You See It
A single faulty string can reduce output across an entire section of a solar array. Thermal anomalies — hotspots, diode failures, and connection issues — often go undetected in SCADA systems until performance degradation becomes measurable.
Early detection allows operators to intervene before revenue loss compounds across weeks or months.
Revenue Impact Illustration
On a 10 MW solar farm, even a 1% undetected performance loss can represent significant annual revenue impact depending on energy pricing and operating conditions.
Structured thermal inspection helps identify these losses early and prioritize corrective action — turning inspection cost into measurable revenue protection.

10 MW Solar Farm — Rapid Defect Identification
Illustrative scenario, not a delivered project. A 10 MW PV site requiring a rapid inspection ahead of a maintenance window would receive thermal and RGB acquisition, severity-classified anomaly referencing, and a structured defect register and report package. Findings would be used by the operations team to prioritize corrective action across the most critical fault clusters.

Solar Inspection Questions
What weather and irradiance conditions are required?
Minimum 600 W/m² irradiance, clear or partly cloudy skies, wind <25 km/h. Inspections are typically scheduled between 10:00–14:00 for optimal thermal contrast. We monitor conditions and reschedule if requirements are not met.
Do you provide radiometric thermal reporting?
Yes. All thermal data is captured using calibrated radiometric thermal capture, providing absolute temperature values for every pixel. This enables accurate ΔT analysis and severity classification per IEC 62446-3.
Can you inspect multi-site portfolios?
Yes. We offer annual framework agreements (Rahmenverträge) for operators managing multiple installations. Standardized methodology and reporting ensures consistency across your entire portfolio.
Are reports suitable for O&M teams?
Reports are structured specifically for operational use — severity-ranked defect registers with GPS coordinates, thermal/RGB image pairs, and maintenance prioritization. Your O&M team can begin corrective action immediately.
How quickly are deliverables returned?
Delivery timing is agreed in the Statement of Work and depends on project scope and reporting requirements. Expedited delivery is available for urgent inspections or pre-maintenance windows where capacity allows.
Do you provide RGB confirmation of findings?
Every thermal anomaly is cross-referenced with corresponding RGB imagery to reduce false positives and provide visual context for maintenance teams.
Thermal inspection identifies likely areas of interest based on infrared signatures. Final condition assessment and any electrical work require validation by a qualified electrician, O&M technician, or licensed engineer. SkyPlotter LLC is not a licensed land surveyor.
