Solar Panel Testing
Professional Solar Panel Testing
Electrical Testing UK carries out solar PV inspection and testing for commercial and industrial sites, and public sector sites. Systems can underperform over time due to issues such as panel degradation, loose connections, inverter faults, or cable deterioration, often without visible signs.
Our engineers inspect and test the full system, including panels, DC cabling, inverter, AC connection, and generation meter, identifying faults, performance losses, and compliance issues, with a detailed report and recommendations.
How Our Service Works
Full System Inspection and Electrical Testing
We inspect and test the entire solar PV system, from panels and DC cabling to inverter, AC isolators, and meter.
Performance and Fault Identification
We detect underperforming panels, faulty connections, inverter issues, and cable deterioration.
Compliance Verification
We verify compliance with BS 7671, MCS standards, and DNO requirements.
Thermographic Imaging Available
Optional thermal surveys identify hotspots and panel faults not visible through standard testing.
Remedial Work Directly Available
Any issues found can be repaired in-house to restore performance and compliance.
Solar Panel Testing for Every Setting & System Type
We provide inspection and testing for solar PV systems across all property types, helping maintain performance, safety, and financial return.
- commercial systems: Testing for site operator installations to identify panel degradation, inverter faults, and connection issues that reduce performance and savings.
- Commercial and industrial systems: Full testing of large-scale systems, including string and panel performance analysis, inverters, and DC/AC circuits.
- Pre-purchase inspections: Testing existing systems before property purchase to confirm condition, performance, and any compliance issues.
- Periodic testing and maintenance: Ongoing inspection programmes to ensure systems remain safe, efficient, and operating as intended.
Solar Panel Testing: FAQs
What does the visual inspection include?
We inspect the full system, including panels, mounting structure, DC cabling, inverter, isolators, and meter, checking for damage, faults, overheating, shading, and signs of wear or moisture ingress.
What electrical tests are carried out?
We test both DC and AC circuits, including string performance (voltage, current, and insulation resistance) and inverter output, ensuring the system is operating within expected parameters and safety limits.
Do you use thermal imaging?
Yes, where required we carry out thermographic imaging to identify hotspots, cell faults, and performance issues not visible through standard testing.
What is included in the report?
You receive a full written report covering inspection findings, test results, faults, performance issues, and prioritised recommendations, suitable for warranties, insurance, and compliance records.
