As the UK faces increasingly unpredictable weather with heavier rainfall, longer damp spells, and sudden temperature drops, solar panel systems are being put to the test. While newer installations can handle these changes, older systems may begin to show signs of wear.
At M J Wallace Limited, we specialise in solar panel fault finding and diagnostics, helping you keep your solar investment performing at its best, whatever the forecast.
The Hidden Risks in Ageing Solar Systems
Solar panels are designed to last for decades, but weather and time inevitably cause deterioration. Constant exposure to moisture, temperature changes, and UV radiation can weaken key components.
A common issue we see is connector failure. These small but vital parts can crack, loosen, or corrode, allowing moisture to enter junction boxes and cabling. Over time, this can lead to humidity buildup and long-term damage.
Common Problems That Develop Over Time
If left unchecked, small faults can grow into serious issues, including:
-
Corrosion of electrical contacts
-
Reduced energy output
-
Intermittent system shutdowns
-
Long-term inverter or battery damage
-
Increased risk of electrical hazards
Many of these problems remain hidden until performance drops or the system fails completely. Regular inspections and proactive fault finding are essential to prevent costly repairs and downtime.
Rapid Diagnostics with High-Precision Technology
At M J Wallace Limited, we use high-precision diagnostic tools to identify problems quickly and accurately. Our technology allows us to:
-
Detect moisture intrusion and insulation breakdown
-
Locate micro-cracks and hotspots in solar panels
-
Test connectors and cabling for continuity and resistance
-
Verify inverter performance and overall efficiency
We don’t just find the issue – we explain it clearly and provide practical, cost-effective solutions. Whether it’s a minor repair or a full system upgrade, our goal is to protect your energy output and your investment.
Seasonal Stress on Solar Systems
Autumn and winter bring unique challenges for solar systems. Damp conditions can accelerate corrosion, while cold snaps can reveal weaknesses in cabling and insulation.
If your solar installation hasn’t been inspected in the past year, now is the perfect time for a professional check. Our solar panel fault finding service gives you peace of mind before the harshest weather arrives. We assess your system’s condition, identify vulnerabilities, and recommend the best steps to maintain efficiency all year round.
