Annual Maintenance & O&M

Planned Care for Your Solar Investment

Solar PV systems are designed for a long working life, but they should not be forgotten once installed.

Inverters can develop faults, electrical connections can deteriorate, monitoring can go offline and damaged components can reduce generation without causing an obvious power interruption.

Solar Support provides planned solar maintenance and operations and maintenance—O&M—services for homes, farms, schools, commercial properties and multi-site portfolios throughout Ireland.

We maintain systems installed by any company and support a wide range of solar, inverter and battery brands.

What Is Solar O&M?

Solar O&M covers the ongoing operation, monitoring and maintenance of an installed solar energy system.

The objective is to:

The exact service level depends on the size, complexity and importance of the installation.

What Can Annual Maintenance Include?

A planned maintenance visit can include:

1
Review of generation and fault history
2
Inspection of accessible panels and mounting
3
Inspection of accessible cabling and connectors
4
Checks of AC and DC isolators
5
Review of protective equipment
6
Inverter condition and operating-status checks
7
Battery condition and performance review
8
Monitoring and communications checks
9
Review of system alerts and error codes
10
Inspection for moisture, corrosion or overheating
11
Bird and pest-damage assessment
12
Visual inspection of labels and shutdown information
13
Firmware and settings review where appropriate
14
Cleaning assessment
15
Written findings and recommended actions

The final scope is agreed before the maintenance plan begins.

Maintenance Based on Your System

Not every solar installation requires the same maintenance schedule.

We consider:

A small residential installation may only need periodic inspection and dependable monitoring. A large commercial system may require scheduled inspections, performance benchmarking, formal reporting and an agreed fault-response process.

Residential Solar Maintenance

Annual Maintenance 01
Inverter Repair

A residential maintenance service can help homeowners confirm that their solar panels, inverter, battery and monitoring remain operational.

It may be particularly useful when:

We will recommend a maintenance schedule appropriate to the system rather than automatically insisting on an annual visit.

Commercial Solar O&M

A commercial solar installation is a working business asset. Even a partial fault can result in lost generation and reduced savings while the property continues purchasing electricity from the grid.

Our commercial O&M services can include:

O&M services can be tailored for businesses, farms, schools, sports clubs, property managers and portfolio owners.

Remote Monitoring

Remote monitoring can help identify:

1
Inverter outages
2
Communication failures
3
Battery charging issues
4
Recurring error codes
5
Unexpected reductions in generation
6
Unusual differences between inverters or sections of an array

Monitoring does not replace physical inspection. It provides visibility of the data reported by the system but cannot identify every roof, mounting, cable or connector defect.

The monitoring frequency and response arrangements will be clearly stated in the selected maintenance plan.

Maintenance Reporting

Following a maintenance visit, you receive a clear record of:

1
Checks completed
2
System status
3
Faults or defects identified
4
Items requiring continued observation
5
Recommended corrective work
6
Available photographs
7
Follow-up actions

Commercial reporting can be adapted for asset owners, property managers, funders, auditors, insurers or sustainability teams.

Repairs and Replacement Parts

The purpose of planned maintenance is to identify and reduce problems—not to create an open-ended repair commitment.

Unless specifically included in your O&M agreement, the following are normally quoted separately:

No additional repair work begins without the customer’s approval.

Warranty Support

Manufacturer warranties may remain valid even where the original installer has ceased trading.

Where a warrantable fault is suspected, Solar Support can help with:

The manufacturer makes the final decision on warranty eligibility.

How Our Maintenance Service Works

1
We gather information about the panels, inverter, battery, monitoring platform and original installation.
2
We assess the system size, environment, available data and customer requirements.
3
You receive a clear description of the inspections, monitoring, reporting and response arrangements included.
4
Maintenance is completed at the agreed intervals, with findings documented.
5
If we identify a fault, we explain the issue and provide a separate quotation where additional work is required.

Frequently Asked Questions

Does every solar system require annual maintenance?

Not necessarily. The right interval depends on the size, equipment, environment and monitoring available. Larger commercial systems generally benefit from a more structured maintenance programme.

Can you maintain a system installed by another company?

Yes. Solar Support specialises in maintaining and supporting existing solar systems, regardless of who installed them.

Are repairs included in an O&M contract?

Only where the agreement specifically says so. Planned inspection and monitoring may be included, while replacement parts and corrective work are normally quoted separately.

Does annual maintenance include panel cleaning?

Cleaning can be included in the agreed plan or arranged when an inspection shows it is necessary. It should not be assumed that every system requires annual cleaning.

Can you maintain several properties?

Yes. We can provide structured maintenance and consolidated reporting for commercial portfolios and multiple locations.

Does maintenance guarantee that the system will never fail?

No maintenance programme can prevent every equipment failure. Planned care helps identify developing issues earlier, reduce avoidable downtime and maintain a clear service history.

Protect the Performance of Your Solar System

Whether you need a one-off maintenance visit or an ongoing commercial O&M programme, Solar Support can build a service around the system you already own.
