Solar panels are low-maintenance, but some care is needed. Discover how to keep your system performing at its best and when to call a professional.
Solar panels are remarkably low-maintenance, typically requiring only occasional cleaning and annual inspections to maintain peak performance over their 25-30 year lifespan.
Key Points
- Clean panels 2-4 times per year, more often if near trees or in dusty areas
- Use a soft brush and lukewarm water - never high-pressure washers
- Monitor your inverter display for error messages and performance drops
- Annual professional inspection costs £100-£200 and ensures warranty compliance
- Most quality panels come with 25-year performance warranties
With minimal maintenance, your solar system will reliably generate clean energy for decades. Annual professional servicing is the best way to protect your long-term investment.
