Panel Cleaning & Inspection

Safe, Professional Cleaning for Your Solar Panels

Rain helps remove loose surface dirt, but it will not always clear bird fouling, salt deposits, moss, lichen, agricultural dust or debris collecting around the panels.

Over time, this build-up can affect generation, particularly on low-pitched roofs, coastal properties, farms and sites close to trees or busy roads.

Solar Support provides professional solar panel cleaning combined with a visual inspection of the array. We service systems installed by any company and work across residential, agricultural and commercial properties throughout Ireland.

Does Every Solar System Need Cleaning?

Not necessarily.

Solar panels installed at a suitable pitch can remain reasonably clean through normal rainfall. Other systems accumulate dirt and debris much more quickly because of their location, roof angle or surrounding environment.

Signs that cleaning may be required include:

We take a condition-led approach. If the panels do not need cleaning, we will not recommend it unnecessarily.

More Than a Panel Clean

Every cleaning visit includes a visual inspection of the accessible solar array.

We look for:

1
Cracked or visibly damaged panels
2
Loose-looking clamps or mounting components
3
Cables that have dropped or moved
4
Damaged or exposed connectors
5
Bird nests and pest activity
6
Leaves and debris trapped beneath the array
7
Signs of overheating or discolouration
8
Obvious roof or flashing concerns around the installation

A visual inspection does not replace a full electrical health check, but it can identify problems that justify further investigation.

How We Clean Solar Panels

Solar panels must be cleaned without damaging the glass, frames, seals, cables or roof covering.

Depending on the property and access available, we use suitable soft-cleaning equipment and controlled cleaning methods. We do not use high-pressure washing around solar panels or electrical connections.

Before starting, we consider:

1
Roof height and pitch
2
Safe access
3
Panel condition
4
Type of dirt or deposit
5
Water availability and quality
6
Surrounding buildings and public areas
7
The size and layout of the solar array

Some panels can be cleaned using specialist equipment from ground level. Other installations require planned roof-access equipment.

Residential Solar Panel Cleaning

Domestic systems may benefit from cleaning where panels are visibly affected by birds, trees, coastal deposits or shallow roof angles.

We can also check whether your inverter and monitoring app show any obvious change in generation before recommending additional diagnostic work.

Farm and Agricultural Solar Cleaning

Solar panels on farms can be exposed to higher levels of dust, bird activity and airborne agricultural material.

We provide cleaning and inspection for solar systems installed on:

The cleaning method and schedule are assessed according to the site conditions and safe access requirements.

Commercial Solar Panel Cleaning

For larger commercial rooftops, we assess the array before providing a cleaning plan.

Commercial services can include:

Cleaning can also form part of a wider commercial operations and maintenance agreement.

Will Cleaning Improve Solar Generation?

It depends on how heavily the panels are affected.

Cleaning lightly soiled panels may produce little measurable difference. Removing heavy or uneven deposits can have a more noticeable effect, especially where part of a panel or string has been significantly obstructed.

We do not promise a fixed percentage increase because the result depends on the condition of the panels, system design, roof orientation and weather.

If the panels are clean but generation remains low, the system may require performance testing or electrical fault-finding.

Frequently Asked Questions

How often should solar panels be cleaned?

There is no single schedule for every system. The appropriate interval depends on the roof pitch, location, surrounding environment and how quickly dirt accumulates.

Can I clean solar panels myself?

Working at height and around live solar equipment presents serious risks. Incorrect equipment or cleaning chemicals can also damage panels and roof coverings. Professional cleaning is the safer option where roof access is required.

Do you use a pressure washer?

No. High-pressure water can affect seals, connectors and roof materials and is not appropriate around solar electrical equipment.

Will you clean beneath the panels?

Accessible debris can be assessed, but extensive nesting material or pest activity may require additional work. Active nests must be treated in accordance with wildlife requirements.

Can you repair a problem found during the inspection?

Yes. If we identify a defect, we will explain what is required and provide a separate quotation before repair work begins.

Do you clean panels installed by other companies?

Yes. We clean and inspect solar systems regardless of the original installer or equipment brand.

Request a Solar Panel Cleaning Assessment

Send us photographs of the solar panels, property address and approximate number of panels. We will review the installation and advise on access, cleaning and inspection requirements.
