Maintenance & service
Long-term monitoring for your installation.
Younergy monitors your installation’s data, analyses what needs to be checked, and intervenes when necessary — without requiring you to become a solar expert.
The benefits
What maintenance and monitoring provide.
Minimise production losses
Detecting an anomaly early reduces the risk of leaving the installation underperforming for weeks.
Avoid unpleasant surprises
Monitoring allows potential issues to be anticipated before they turn into major or costly call-outs.
Save time when an issue arises
With system data already at hand, diagnosis is quicker and on-site visits are better prepared.
Preserve the value of your installation
A system that is monitored and maintained over time maintains its proper operation and performance far more reliably.
After commissioning
What happens once the system is connected.
Younergy’s role does not end at commissioning: it simply evolves.
Assessment and system sizing.
Equipment installation by our teams.
Grid connection and initial startup.
Ongoing monitoring of your solar installation.
Common observations
Situations that may require an intervention.
01
My solar output has dropped
A sustained drop in generation can stem from various causes. Production data helps identify where to look before calling out a technician.
02
My inverter displays an error
A fault code does not necessarily mean the inverter must be replaced. The underlying cause and its impact on the system must be identified first.
03
I no longer have access to monitoring
A loss of monitoring may be due to internet connection, communication hardware, or the platform, without generation necessarily being interrupted.
04
Some panels appear damaged
A cracked, displaced, or visibly altered module warrants an inspection to determine whether the issue remains isolated or affects the rest of the array.
05
I have just bought a home with an existing system
A comprehensive assessment helps you better understand the existing installation, its components, how it operates, and any points to monitor.
06
I simply want to have my installation checked
Even without an apparent fault, a one-off inspection clarifies its overall condition and establishes a solid benchmark for years to come.
Tailored to your needs
Two monitoring options for your installation.
Need a one-time assessment today or prefer long-term professional monitoring?
One-off inspection
Find out exactly where your installation stands.
A single point-in-time check to assess its condition, clear up any doubts, or prepare your next steps.
Get a clear assessment
Have your installation checked after several years in operation, when buying a property, or simply to know its actual condition.
Pinpoint the root cause of an issue
Drop in yield, inverter fault, or monitoring offline: an inspection targets the exact issue rather than troubleshooting blindly.
Make informed decisions before commissioning work
A diagnosis determines whether you simply need to clear a fault, replace a component, or consider a broader upgrade.
Continuous monitoring
Your system stays monitored with Younergy.
Long-term monitoring keeps an eye on performance without requiring you to review system data regularly.
Minimise time spent underperforming
When an anomaly is visible in system data, it can be caught early instead of going unnoticed until your next manual check.
No longer rely on manual checks
You do not need to worry about regularly checking the app or monitoring production metrics to see if something has changed.
Maintain a valuable track record
Tracking performance and system events provides essential context whenever an issue or service call-out needs review.
Keep your installation reliable, just like they do.
Inspect your system and anticipate risks.
Whether through a one-off inspection or continuous monitoring, the goal is always to know what is happening before it becomes a noticeable problem.
Four maintenance approaches
Intervene only when necessary.
Monitoring, inspecting, repairing, and servicing meet distinct needs, depending on the situation and whether an on-site visit is required.
| Scheduled | Unscheduled | |
|---|---|---|
| Remote | Monitor Generation is monitored continuously and remotely: no physical visit is needed as long as performance data remains consistent. | The starting point This is where an unexpected anomaly is most often first detected via remote monitoring before triggering an on-site visit, if needed. |
| On site | Inspect A scheduled on-site inspection to objectively assess the physical condition of the installation beyond what data alone reveals. | Intervene A site visit organised because a detected or reported anomaly requires physical action on site. |
Care
Maintain
Cleaning and physical maintenance are always carried out on site — whether planned as part of a routine visit or following a service call-out. This is not governed by a rigid schedule: frequency depends on roof pitch, ambient dust, or surrounding vegetation.

Cleaning
Recommended depending on roof pitch, ambient dust, nearby agricultural activity, or surrounding vegetation — not on a rigid schedule.

Thermal imaging and advanced diagnostics
Used to investigate specific anomalies — such as abnormal overheating —, not as a routine service.

Three types of call-outs
Your installation will always be covered.
01
Warranty
Governed by product or installation terms. It covers specific defects under its own conditions — irrespective of any maintenance contract.
02
Maintenance
Monitoring and services provided under your chosen plan — Silver, Gold, or Ultra. What Younergy handles for you over the long term.
03
Out-of-warranty / out-of-contract work
Any situation not covered by warranty or your current contract can be quoted separately.
Exact contract terms and conditions should be confirmed with your Customer Service coordinator.
Beyond the panels
When maintenance extends beyond solar modules.
Adding a battery changes how the system should be monitored.
A battery does not follow the same servicing logic as a solar panel, whereas panels themselves require very little ongoing attention. Where a battery is installed, the Ultra plan already includes this maintenance: monitoring usage patterns, charge cycles, and overall system health over time delivers the greatest value, long before an issue becomes visible.
Beyond solar, this same monitoring logic can also be applied to other Smart Energy equipment. However, the priority remains ensuring your existing setup is thoroughly covered.

FAQ
No. A solar installation has no moving parts and does not require mandatory regular servicing. Monitoring generation and occasional visual checks are sufficient in most cases.
There is no single rule. A visual check every two to three years, or following significant adverse weather, is good practice. A maintenance contract provides more continuous monitoring if desired.
Not systematically. Rain washes away most ordinary dirt. Professional cleaning becomes worthwhile depending on roof pitch, proximity to agricultural or dusty areas, or surrounding vegetation.
Historical production data and any inverter error messages are the most reliable indicators. A Gold or Ultra plan includes monitoring and an annual performance review to assess this objectively.
The situation is first analysed using available data. An on-site visit is only scheduled when genuinely required.
Yes. A one-off inspection can easily be arranged. A no-obligation quote can be requested from Younergy.
