Why Solar Panel Cleaning Matters

Solar installations lose efficiency when panels are covered by dust, pollen, bird droppings, or other surface contaminants. Even a small layer of residue can reduce power generation by 5 to 20 percent. Regular professional cleaning helps maintain peak performance and ensures the system operates as designed.

Common client goals include:

Maximising energy yield and ROI

Protecting long-term panel performance

Meeting sustainability and ESG commitments

Maintaining safe and compliant access to roof systems

Frequently Asked Questions

Still need help? Get In Touch

How often should solar panels be cleaned?

For most Irish sites, we recommend cleaning every six to twelve months, depending on environmental conditions and panel exposure.

Does rain clean solar panels effectively?

Rain alone does not remove fine dust, pollen, or organic residues. Professional cleaning ensures consistent performance and warranty compliance.

Can you clean panels while systems are active?

Yes. Cleaning is completed safely while systems remain operational, following manufacturer and electrical safety guidance.

What safety measures do you use for rooftop systems?

All technicians are trained in working at height and use certified fall protection and access equipment.

Do you offer ongoing maintenance programmes?

Yes. We can schedule regular cleans based on system monitoring data or seasonal performance trends.
