Warranty & Aftercare
Peace of Mind for Every Solar PV System
At Solar Plants Maintenance LTD, we believe every solar system deserves lasting protection, even if the original installer is no longer around.
Whether your panels are new, several years old, or recently purchased with your home, we can provide ongoing warranty cover and aftercare services to keep your system secure and efficient for years to come.
​
Do You Offer Extended Warranties?
Yes, we do. If your current solar PV system is out of warranty, or if you’ve bought a home where the original provider has gone out of business, we can issue a new 10-year workmanship warranty.
​
This gives you full protection for:
Electrical and mechanical workmanship
Mounting structure integrity
Cable connections and terminations
Safety and compliance of installation standards
​
Before we activate your warranty, our team performs a comprehensive system inspection to confirm everything is safe, compliant, and operating efficiently. Once complete, you’ll receive official documentation outlining your new warranty terms.
​
What’s Covered Under Our Aftercare Plans
Our aftercare service goes beyond warranty protection, it’s designed to keep your solar system in peak condition:
Annual or bi-annual cleaning and inspection
Performance and fault monitoring
Inverter testing and firmware updates
DC and AC electrical checks
Bird and pest protection maintenance
System upgrade advice for SolarEdge, Enphase, and other leading brands
​
We provide both one-off inspections and ongoing maintenance contracts, depending on your system’s age and requirements.
​
Bought a Property with Solar Panels?
​
If you’ve recently purchased a home with an existing solar system, we can:
​
Inspect the installation for safety and compliance
Provide a performance health report
Issue a new 10-year warranty under your name
Offer ongoing maintenance and cleaning packages
​
This service is ideal for homeowners who’ve lost contact with the original installer or want to ensure their investment remains covered.
