Sunbury, Surrey. April 24th 2025 – Rayotec, a leading provider of renewable energy solutions with over 35 years of industry experience, is urging UK homeowners to prioritise regular maintenance of their solar panel systems to maximise efficiency, extend lifespan, and ensure optimal financial returns on their renewable energy investments.
As solar adoption continues to grow across the UK, with installations reaching record numbers in recent years, Rayotec’s solar maintenance experts emphasise that many homeowners are unaware of the performance degradation that can occur without proper maintenance, potentially costing them thousands in lost energy production and premature system failures.
“Many homeowners assume solar panels are completely maintenance-free, but this is a costly misconception,” explains Rayotec’s Head of Solar Services. “While solar systems are indeed robust, factors such as weather exposure, component degradation, and wiring issues can significantly impact performance over time. Our data shows that well-maintained systems can produce up to 25% more energy than neglected installations.”
Rayotec’s announcement comes as part of their expanded solar maintenance service, which caters to both Solar PV (photovoltaic) systems generating electricity and solar thermal systems for hot water. Their comprehensive maintenance approach includes thorough system inspections, performance monitoring, repairs, and component replacements when necessary.
The company highlights several key reasons why maintenance matters:
- Extended System Lifespan: Regular professional checks can add years to a system’s operational life
- Optimised Energy Production: Clean, well-maintained panels and properly functioning inverters ensure maximum energy generation
- Warranty Protection: Most manufacturers require evidence of maintenance to honour warranty claims
- Safety Assurance: Professional inspections identify and address potential electrical hazards before they become dangerous
- Financial Protection: Preventing minor issues from developing into major, costly repairs
For homeowners uncertain about their maintenance needs, Rayotec recommends following industry best practices: commercial systems should be checked annually, while domestic PV systems should be inspected every 10 years (or every 5 years for rental properties). Solar hot water systems require more frequent attention, with inspections and antifreeze replacement recommended every four years.
“Solar energy represents a significant investment in both sustainability and financial savings,” adds Rayotec’s spokesperson. “Proper maintenance protects that investment and ensures homeowners receive the full environmental and economic benefits these systems can provide.”
Rayotec’s expanded solar maintenance service is now available across London and the South East, backed by their status as Which? Trusted Traders and NICEIC Approved Contractors. Their expertise is reflected in their impressive client roster, which includes prestigious organisations such as Harrods, Netflix, and Ocado.
