- Detect faults early—before they affect energy generation.
- Prevent output loss caused by dirt, weather damage, or wildlife interference.
- Extend the lifespan of your solar panels, inverters, and cabling.
- Safeguard your energy savings and maximise long-term return on investment.
With just one professional check-up each year, you can ensure your system continues to operate efficiently—no surprises, no downtime.

Troubleshooting Common Solar Issues
We handle a range of common issues to keep your solar system running smoothly:
- Inverter errors or red warning lights
- Reduced energy output caused by dirt, shading, or debris
- Wildlife interference or damaged cabling
- Monitoring system malfunctions
- Cracked or weather-damaged panels
Not sure what’s wrong? Begin by checking your generation meter against expected values, reviewing inverter error codes, and ensuring no circuit breakers or isolators have tripped. If problems continue, our expert engineers are on hand to diagnose and fix the issue promptly.
Solar Panel Cleaning & Bird Protection
Although solar panels are largely self-cleaning thanks to rain, dust, bird droppings, and debris from nearby trees can accumulate and reduce performance over time. Our expert team conducts thorough assessments to determine if cleaning is needed and provides tailored recommendations to maintain optimal efficiency. Additionally, we offer advice and solutions for pigeon-proofing your solar installation during the setup phase. Prevent bird nests and potential damage to your system, safeguarding your investment for the long term.
Inverter Support & Lifespan Checks
Inverters generally have a lifespan of 10 to 15 years and are more susceptible to faults than solar panels. To help prolong their life, we perform thorough checks on ventilation to prevent overheating and assess dust build-up that can affect performance. We also carry out firmware updates and calibration routines to ensure optimal operation. Our team monitors manufacturer-specific error codes to detect issues early. If your inverter requires replacement, we provide fast, efficient, and compatible upgrade solutions to minimise disruption and maintain your system’s energy output.
