Annual care
Annual System Health Check
A full visual inspection, electrical safety testing and a generation-performance review against the expected system output.
Maintenance, monitoring and long-term support
Your system should keep working long after installation day.
REST UK supports solar and home-energy systems with annual health checks, proactive monitoring, warranty coordination and optional maintenance services.
Annual system reviews
Remote performance alerts
Warranty and protection support
Aftercare that stays useful
Practical support for the system already on your property.
The service is focused on system condition, performance, warranty support and clear next steps — not turning every aftercare enquiry into a new sales conversation.
Warranty support
Inverter Replacement Service
If an inverter fails during its manufacturer warranty period, REST UK manages the claim and coordinates the replacement process.
Optional add-on
Optional Panel Cleaning Service
Dust, debris and environmental build-up can affect generation. An optional annual clean helps restore the panels to a clearer working surface.
Consumer protection
HIES Independent Builder's Guarantee
Qualifying workmanship cover is backed by an independent insurance policy and is designed to remain valid separately from REST UK's business continuity.
Long-term performance
25-Year Panel Performance Guarantee
The selected Eurener panel range includes long-term manufacturer performance guarantees, with the exact output milestones confirmed in the product documentation supplied with the system.
Proactive monitoring
24/7 Fleet Monitoring Alert
Where remote monitoring is active, system alerts can flag underperformance so the aftercare team can review the issue before it becomes an obvious problem.
How REST aftercare works
Monitor. Assess. Resolve.
A simple support process keeps the focus on identifying the issue and agreeing the right response.
Review the system
REST checks the information available from monitoring, customer reports and system documentation.
Assess the next step
The team confirms whether the issue needs remote guidance, a health check, warranty action or maintenance work.
Coordinate the solution
REST arranges the agreed service and explains any warranty position, chargeable work or manufacturer involvement.
Remote monitoring, warranty support and replacement availability depend on the installed products, connectivity, documentation and applicable manufacturer terms.
Support beyond installation
A clearer route when something does not look right.
Generation can change for many reasons, including weather, shading, connectivity, equipment settings and component faults. REST aftercare helps separate normal variation from issues that need attention.
- Review monitoring information and customer observations
- Explain whether a site visit is appropriate
- Coordinate compatible manufacturer warranty claims
- Provide a clear route for optional maintenance
Maintenance questions
What to know before booking aftercare.
These answers explain the difference between routine maintenance, monitoring, manufacturer warranties and chargeable repair work.
The visit can include a visual inspection of accessible system components, electrical safety checks and a review of generation performance against the available system information. Any further work is discussed separately.
REST can review suitable third-party installations, but the available service depends on the equipment, documentation, access, condition and whether replacement parts or manufacturer support are still available.
No. Panel cleaning is an optional add-on. REST will discuss whether cleaning is appropriate for the property, roof access and visible level of build-up before arranging the service.
REST can assess the fault, review the manufacturer warranty position and coordinate the claim and replacement route where the system and warranty terms allow it. Work outside warranty may be chargeable.
Where compatible remote monitoring is active and REST has access to the relevant alert information, the aftercare team can review flagged underperformance and contact you about the next step.
No. A panel performance guarantee normally relates to the panel manufacturer's retained-output commitment under specified conditions. Actual annual generation still changes with weather, shading, system condition, roof orientation and household circumstances.
