Although solar panels are low maintenance, they are not completely maintenance-free. Over time, small issues can develop that affect performance, even if the system still appears to be working normally.
A typical solar service involves a full system check, including: panel condition, inverter performance, electrical connections, and overall energy output. This helps ensure everything is operating safely and efficiently.
In Surrey, including Woking, Esher, Guildford and Cobham, environmental factors like seasonal tree growth, bird activity, and weather exposure can gradually impact system performance.
While rainfall helps keep panels relatively clean, it does not remove all debris. Subtle issues like shading or minor faults can reduce output without being obvious to the homeowner.
What servicing usually includes:
- Visual inspection of panels and roof
- Inverter and system diagnostics
- Performance review of energy output
- Identification of shading or faults
Most systems benefit from servicing every 1–2 years to maintain long-term efficiency and catch issues early.
