How Often Should You Service Your Solar Panels?
Solar panels are an excellent investment for reducing energy costs and lowering your carbon footprint. However, like any long-term investment, maintaining your solar PV system is essential to ensure safety, efficiency, and performance over time. While solar panels are generally low maintenance, regular servicing helps maximise lifespan and return on investment. Voltify Solar advises homeowners to carry out routine checks to keep systems operating at their best.
This article explains how often solar panels should be serviced, what the process involves, and how you can safely carry out basic checks yourself.
Do Solar Panels Need Servicing?
Solar panels are designed with no moving parts, making them relatively low maintenance. However, the wider system includes components such as the inverter, mounting system, cabling, and consumer unit connections, all of which require periodic attention.
Suffolk’s weather conditions, including rain, moss, bird droppings, and debris, can also impact performance. It’s important to understand the difference between solar panel servicing and basic cleaning to maintain optimal system efficiency.
How Often Should You Service Your Solar Panels?
Recommended Servicing Schedule
- Professional Service: Every 1–2 years.
- Visual Inspection: Every 6–12 months.
- Inverter Check: Annually (or according to manufacturer guidelines).
Factors That May Require More Frequent Servicing
Certain conditions might necessitate more frequent servicing:
- Coastal Locations: Risk of salt corrosion.
- Rural or Agricultural Areas: Dust and debris can accumulate.
- Properties with Heavy Tree Cover: Increased likelihood of shading and debris.
- Noticeable Drop in Energy Output: Indicates potential issues.
Most Suffolk homeowners won’t need frequent intervention unless they notice a performance drop.
What Does Solar Panel Servicing Involve?
Visual Roof Inspection
- Check for cracked panels.
- Inspect for loose brackets.
- Look for shading from new tree growth.
Electrical System Check
- Test inverter performance.
- Check DC and AC isolators.
- Inspect cabling and connections.
- Review generation meter readings.
Performance Testing
- Compare current output to expected yield.
- Identify underperformance issues.
Cleaning (If Required)
- Safely remove debris.
- Avoid pressure washing.
- Consider professional cleaning when necessary.
How to Check Your Solar Panels Yourself
For those interested in performing basic checks, here are some safe homeowner practices:
- Monitor the inverter display for error messages.
- Review generation data via the monitoring app.
- Compare monthly generation to previous years.
- Look for visible dirt or shading from the ground (never climb onto the roof).
- Listen for unusual inverter noises.
Warning Signs You Need Professional Help
- Sudden drop in output.
- Flashing warning lights.
- Tripped breakers.
- Physical panel damage.
Safety Note: Homeowners should not attempt electrical work.
What Happens If You Don’t Service Your Solar Panels?
Neglecting regular servicing can lead to:
- Reduced efficiency.
- Gradual performance decline.
- Potential warranty issues.
- Undetected electrical faults.
- Shorter inverter lifespan.
Regular servicing is crucial for protecting long-term savings.
Does Servicing Affect Your Warranty?
Many manufacturers require periodic inspections. It is important to use qualified professionals and retain servicing records for warranty and insurance purposes.
The Lifespan of a Solar Panel System
- Panels: Typically last 25+ years.
- Inverters: Usually require replacement after 10–15 years.
Regular servicing helps systems reach their full lifespan.
When Should You Book a Professional Solar Panel Service?
Consider booking a service if:
- Your system is over 12 months old and hasn’t been checked.
- You’ve noticed reduced generation.
- You’re preparing to sell your property.
