Solar Panel Maintenance: Tips to Maximise Performance
Investing in solar panels is a great way to reduce your energy bills, lower your carbon footprint, and become more energy independent. But to ensure you get the best performance from your system for years to come, regular solar panel maintenance is essential.
At East Green Energy, we help homeowners and businesses across East Anglia get the most from their solar power systems. In this guide, we’ll cover why maintenance matters, common issues to look out for, and simple steps to keep your panels operating efficiently.
Why Is Solar Panel Maintenance Important?
Solar panels are designed to be durable and low maintenance, but that doesn’t mean they can be ignored completely. Regular upkeep helps to:
Maximise energy production – Dust, dirt, and debris can block sunlight and reduce efficiency.
Extend the lifespan of your system – Well-maintained panels can last 25+ years.
Identify potential issues early – Catching problems before they escalate can prevent costly repairs.
Maintain warranty coverage – Some manufacturers require periodic maintenance to keep warranties valid.
Common Issues That Affect Solar Panels
Even though solar panels are built to withstand the elements, a few factors can reduce their performance over time:
Dirt and Debris – Dust, leaves, and bird droppings can cover the panels and block sunlight.
Weather Damage – Strong winds, heavy rain, and hailstorms can occasionally cause minor damage.
Shading Issues – Tree growth or new structures nearby can cast shadows that reduce energy generation.
Electrical Faults – Loose wiring or inverter issues can affect the system’s output.
By carrying out simple maintenance checks, you can catch these issues before they impact your system’s efficiency.
Solar Panel Maintenance Tips
1. Keep Panels Clean
How often? Once or twice a year, or more frequently if you live in a dusty area.
Dirt buildup can reduce efficiency by up to 25%, so cleaning your panels is essential. Use a soft brush and water to gently remove grime—avoid using harsh chemicals or abrasive tools.
If your panels are hard to reach, consider hiring a professional solar cleaning service.
2. Check for Shading Issues
How often? Annually or after significant tree growth.
Solar panels work best when fully exposed to sunlight. If nearby trees are starting to cast shadows on your system, trimming them back can boost your energy production.
3. Inspect for Damage
How often? After severe weather events or annually.
While solar panels are built to withstand tough weather, storms can sometimes cause cracks, loose wiring, or frame damage. A quick visual check ensures your system stays in top condition.
4. Monitor Energy Output
How often? Daily.
Most modern solar systems come with a monitoring app that tracks your energy production. If you notice a sudden drop in output, there could be an underlying issue that needs attention.
5. Schedule a Professional Inspection
How often? Every Year..
A professional solar inspection can catch electrical issues, inverter problems, and panel inefficiencies that might go unnoticed. East Green Energy offers solar health checks to keep your system running at peak performance.
