Spot changes in production
Dirt, shading, error messages and cooling problems can affect production. Reviewing the data and equipment helps establish whether a change needs attention.
PERFORMANCE, CONDITION AND A CLEAR OVERVIEW
Solar PV system
maintenance
Maintenance helps identify irregularities and keep track of your solar PV system’s condition. We check panels, mounting, the inverter and electrical connections, then explain any issues we find.

MAINTENANCE IS PREVENTIVE WORK
Even a working system
needs attention
An inverter showing production does not tell you everything about the system’s condition. Maintenance combines a review of production data with a physical inspection.
Check what the app cannot show
Mounting, cables and connections need a separate inspection. A physical check can reveal damage and wear that a production chart alone cannot explain.
Know what to do next
The maintenance report records the work done and any defects found. It helps you plan repairs, track the system’s condition and provide relevant information to the manufacturer when needed.
WHAT DO WE CHECK?
Solar panel maintenance
is more than washing
The exact scope depends on your equipment and the work agreed. We start by assessing the system’s condition and follow the manufacturer’s maintenance instructions.
Repairs, spare parts, panel washing and additional investigations are agreed separately when needed. The maintenance quotation specifies which work is included.
- 01
Panels and mounting
Visible condition of panels, frames and mounting, including possible damage. For ground-mounted systems we also consider vegetation and access.
- 02
Inverter and cooling
Device messages, visible condition and cleanliness of cooling and ventilation. Cleaning follows the requirements for the particular model.
- 03
Cables and electrical connections
The condition of cables, connections and protective earthing within the agreed inspection scope. Damage and defects are documented.
- 04
Measurements suited to your system
Electrical measurements are selected according to the system, manufacturer’s instructions and inspection purpose. Not every test is appropriate for every installation.
- 05
Production and monitoring
We review available production data and error messages, including whether an apparent production issue could instead be a communication problem.
- 06
Report and recommendations
You receive an overview of the inspections and defects found. Additional work and the next maintenance plan are agreed separately.
MAINTENANCE NEEDS VARY
When should you
plan maintenance?
The interval depends on manufacturer guidance, location, environment and previous condition. Dusty surroundings or recurring faults may require more frequent attention.
Watch production and messages
Review monitoring trends and error messages. Compare similar periods and allow for weather, seasons and possible grid restrictions.
Arrange a routine inspection
We plan inspections around your system’s needs. Reviewing maintenance needs annually helps keep track of completed work and next steps.
Do not wait for the next service
A recurring error, unexpected production change or storm damage is a reason to contact us earlier and assess whether an inspection is needed.
One-off maintenance
Suitable when you want to assess the system’s current condition or plan its next inspection.
Maintenance agreement
We agree the scope, frequency and notification procedure. Response times and warranty work conditions are defined in the agreement.
WHEN SHOULD YOU CONTACT US?
If your system’s behaviour
has changed
Describe what you noticed and when the change began. If monitoring is available, include the error code or a screenshot.
Describe the problem- Production has unexpectedly fallenThe change recurs in comparable conditions and is not explained by weather or season alone
- The inverter shows recurring messagesThe error, frequency and timing help determine the next checks
- You see damage or a loose componentCables, mounting or panels have visibly changed, for example after a storm
- Monitoring data is missingCommunication loss must be distinguished from a production outage
If you notice smoke, a burning smell or another immediate hazard, keep your distance Do not open equipment or touch cables. If life, health or property is at risk, call 112. The maintenance enquiry form is not an emergency channel.
WHAT CAN YOU DO YOURSELF?
You monitor,
a specialist inspects
Your observations help describe problems sooner. Opening equipment and electrical inspections require specialist knowledge and appropriate working methods.
For the owner
- Follow monitoring messages and production trends
- Photograph visible changes from a safe position
- Keep equipment models and previous reports to hand
- Describe when the problem started and whether it repeats
For the specialist
- Electrical connection checks and measurements
- Opening, servicing and repairing equipment
- Roof inspections and mounting work
- Cleaning and configuration according to manufacturer guidance
FREQUENTLY ASKED QUESTIONS
Solar PV maintenance
without confusion
The maintenance plan is based on your system. We agree the work, scope and price before carrying it out.
Ask about your systemIs a solar PV system maintenance-free?
Low maintenance does not mean no maintenance. The system includes an inverter, mounting, cables and electrical connections as well as panels. Their condition and manufacturer-specified maintenance needs should be assessed regularly. Monitoring helps spot changes but does not replace physical inspection.
Does every solar PV system need annual servicing?
There is no single work list or interval for every system. Follow equipment guidance and consider the environment and condition. An annual review of maintenance needs is a practical starting point; some devices or dusty locations may need more frequent checks.
Is panel washing always included?
Panel washing is generally not included in maintenance and can be agreed as a separate service. We have specialist washing equipment with brushes and a long telescopic pole, which is also available to rent. Washing must follow the panel manufacturer’s instructions.
Does lower production always mean a fault?
Not always. Weather, seasons, shading, dirt and grid conditions affect production. Missing monitoring data may also be caused by communication loss. We review when the change began, its duration and any messages before deciding whether an on-site inspection is needed.
Is maintenance a condition of the warranty?
This depends on the equipment manufacturer’s warranty and maintenance instructions and your agreement. A report documents the work but does not guarantee acceptance of a warranty claim. The scope and any labour or transport costs must be checked for each case.
Are defects repaired immediately during maintenance?
It depends on the defect and agreed scope. Inspection and repair are not always the same service. If spare parts or additional work are needed, we explain the requirement and agree the solution and price. Safety-related defects require particular attention.
How much does maintenance cost?
The price depends on system size, number of devices, location, access and required inspections. Rooftop and ground-mounted systems may need different amounts of work. Send the address, system capacity and your request so we can define the scope and quotation.
Does a solar PV system with a battery need maintenance too?
Yes, but the battery’s maintenance needs must be assessed separately under its manufacturer’s guidance. Adding a battery does not replace inspections of panels, the inverter and the electrical installation. Include the battery model and any messages in your enquiry. Learn about battery storage.
