Solar Panel and PV System Fires
Solar energy systems combine electrical, structural, and mechanical components, which can create fire risks when failures occur.
Overview
Understanding Solar Installation Fires
Solar fire investigations require familiarity with PV system design, National Electrical Code requirements for solar installations, and the unique fire behavior characteristics of DC electrical systems operating at high voltages.
Solar installations involve high-voltage equipment, extensive wiring, and constant environmental exposure. Our investigations combine electrical analysis, material evaluation, and industry standards to provide accurate conclusions.
Solar installation fires have increased as photovoltaic systems have become widespread. Common fire causes include DC arc faults, connector failures, inverter malfunctions, improper wiring, and roof penetration issues. Our engineers understand both the electrical engineering and fire science aspects of these investigations.
What We Do
Panel & Module Analysis
We evaluate photovoltaic panels for defects, overheating, and material degradation that may have contributed to ignition.
Inverter & Electrical Systems
We analyze electrical performance, installation quality, and component failure to identify root causes.
Installation & Workmanship
We review system design and construction methods to determine their role in the incident.
Environmental & Maintenance Factors
We assess environmental stresses and maintenance practices to identify whether they contributed to system failure.
Methodology
Our Process
System Documentation
Document the complete PV system including modules, inverters, combiners, disconnects, wiring, and mounting hardware. Record system specifications and installation details.
Electrical Analysis
Trace DC and AC circuits to identify arc fault locations, damaged conductors, failed connections, and code violations. Evaluate inverter and rapid shutdown system operation.
Installation Evaluation
Assess installation quality including conductor routing, connection methods, roof penetrations, and compliance with NEC Article 690 and manufacturer requirements.
Component Examination
Examine failed components in detail. Test and compare against manufacturer specifications and industry standards.
Cause Determination
Identify the specific failure mechanism and determine whether the cause was a design deficiency, installation error, component defect, or maintenance issue.

Common Questions
FAQ
Are solar panel fires common?
While solar fires are relatively rare compared to other electrical fires, their frequency has increased with the growth of solar installations. DC arc faults, connector failures, and installation errors are the most common causes.
Can solar panels cause a fire even when the system is turned off?
Yes. Solar panels generate DC voltage whenever exposed to light. Unlike AC systems, you cannot simply turn off solar panels. This is why rapid shutdown systems and proper DC wiring practices are critical.
Do you investigate ground-mounted solar farms as well as rooftop systems?
Yes. We investigate fires in residential rooftop systems, commercial roof-mounted arrays, ground-mounted solar farms, and solar carport structures.
