Homeowners can support solar performance during autumn with a few practical, safety-conscious checks:
1. Carry Out a Ground-Level Visual Inspection
A periodic visual check from ground level — or from an accessible upstairs window — can help you spot leaf build-up, bird activity or shading from new growth on nearby trees. There is no need to climb onto the roof, and professional assistance should be sought for any cleaning or physical maintenance.
2. Monitor Output Through Your Inverter or App
Modern PV systems provide real-time or historic generation information. If output appears unexpectedly low for the season and weather conditions, debris or shading could be a contributing factor.
3. Keep Gutters Clear
Leaves that slide off solar panels often collect in gutters, increasing the risk of blockages. Clear guttering helps ensure proper drainage and reduces roof-moisture issues throughout autumn and winter.
4. Consider a Professional Clean if Needed
Although panels are designed to be largely self-cleaning, areas with heavy tree coverage or ongoing leaf fall may benefit from an occasional professional clean. This should only be carried out by trained installers using the correct equipment to avoid damage or personal safety risks.
Safety First: Avoid DIY Roof Work
It is important to note that no maintenance task is worth compromising safety. Climbing onto a roof presents significant risk, particularly during wet or windy autumn conditions. Always engage a qualified professional if leaves or debris need to be removed from hard-to-reach areas or from beneath a solar array.
Looking Ahead to Winter
Taking simple steps in autumn can help ensure your solar panels are prepared for the harsher winter months. By reducing leaf build-up and monitoring system performance, homeowners can support steady generation throughout the darker season and maximise the long-term return on their investment.
Supporting Long-Term Solar Performance
Solar panels are a low-maintenance, long-life technology, and seasonal awareness can help protect their output for years to come.
