Solar System Repairs & Fault Finding
System not performing as expected? We provide fast, professional solar PV repair services across East Sussex. From simple fixes to complex fault-finding, our MCS certified engineers get your system back to peak performance.
What’s Included in a Repair Visit
Our diagnostic visits are comprehensive. We don’t just look at the obvious fault — we test the whole system so nothing is missed.
Initial Diagnostic Consultation
We discuss your symptoms and system history before arriving so our engineer comes prepared with the right equipment.
Visual Inspection of Panels & Mounting
Full roof-level inspection of every panel, frame, clamp, and roof penetration for physical damage, soiling, or mounting defects.
Thermal Imaging Scan
Thermal camera identifies hot spots, failing cells, bypass diode faults, and connection problems invisible to the naked eye.
Electrical Performance Testing
Irradiance and temperature-corrected output measurements compared against rated specifications to identify underperforming panels or strings.
Inverter & Communications Check
Fault codes, error logs, and communication status checked on the inverter. We test data logging, monitoring portal connection, and firmware version.
DC String Voltage & Current Measurements
Each string measured individually with a clamp meter to identify open circuits, partial shading effects, and current imbalances.
Wiring & Isolator Inspection
All accessible DC and AC wiring, isolators, and connectors checked for condition, tightness, corrosion, and compliance.
Written Fault Report with Photos
Every fault is documented with photographs. The report explains what is wrong, why, and what we recommend — in plain English.
Transparent Quote Before Work Begins
You receive an itemised repair quote before we touch anything. Work only proceeds once you have approved the cost.
Component Sourcing & Replacement
We source genuine replacement parts directly from manufacturers. Common components are carried on-vehicle for same-visit repairs.
Full Commissioning Test After Repair
After repairs are complete we re-run the full electrical test sequence to confirm the fault is resolved and the system is performing correctly.
Performance Verification Report
A written report confirming post-repair output measurements, signed off by our engineer. Useful for warranty claims and insurance purposes.
Common Solar System Faults We Fix
From minor issues to major failures, we’ve seen and fixed it all. Here are the most common faults we encounter across East Sussex.
Low Energy Production
System generating less than expected? We identify shading, soiling, panel degradation, or configuration issues using irradiance-corrected output measurements.
Connection Problems
DC isolator failures, loose connections, corroded cables, or junction box faults affecting power flow. Often causes partial or intermittent generation loss.
Physical Damage
Cracked panels from storms, fallen branches, or hail. We assess the extent of damage, replace affected modules, and verify the mounting structure is undamaged.
Animal Damage
Squirrel, bird, or rodent damage to DC wiring is one of the most common faults we attend. We repair cables and can install protective pigeon mesh to prevent recurrence.
Water Ingress
Leaking roof penetrations, damaged junction box seals, or moisture infiltration causing corrosion or short circuits. We trace the source and make watertight repairs.
Electrical Faults
Earth faults, arc faults, overvoltage protection trips, or MCB/RCD issues in AC and DC circuits. We carry test equipment to safely locate and resolve electrical faults.
Our Repair Process
We follow a consistent four-step process on every job — from the first diagnosis to the final sign-off.
- 1
Diagnostics
On-site · 1–2 hoursOur engineer arrives with thermal imaging camera, clamp meter, and irradiance meter. We carry out a full visual inspection of the panels, racking, wiring, and inverter, followed by electrical performance measurements across every string.
- Thermal imaging identifies hot spots, cell failures, and bypass diode faults
- String voltage and current measured against manufacturer specifications
- Inverter fault codes and communication logs reviewed
- 2
Fault Report
Same day · written reportWe produce a written fault report with photographs of every issue found. The report clearly explains what is wrong, what caused it, what we recommend, and — where relevant — whether any fault is covered by your panel, inverter, or workmanship warranty.
- Photos of every fault included in the report
- Clear explanation of root cause and impact on generation
- Warranty status noted for each affected component
- 3
Quote & Repair
Transparent pricing · no hidden costsWe provide a clear, itemised quote for all recommended repairs before any work begins. Once approved, we source components and carry out the repair — often on the same visit for minor faults, or on a scheduled return for parts that need ordering.
- Itemised quote provided before work starts — no surprises
- Many common parts carried on our vehicles for same-visit repairs
- Warranty parts ordered direct from manufacturers where applicable
- 4
Testing & Sign-off
Full commissioning testAfter completing repairs, we carry out a full commissioning test — verifying string voltages, inverter output, monitoring connectivity, and live generation against expected output for the conditions. We issue a written performance verification report before we leave.
- String voltages and inverter output re-measured post-repair
- Live generation verified against expected output for current irradiance
- Written performance verification report issued on completion
