Case Study: Commercial Solar Panel Cleaning & Gutter Clearance in South Wales
Project Overview
We recently completed a large-scale commercial solar panel cleaning and gutter clearance project in South Wales, supporting a commercial client with high-level roof maintenance. The site required specialist access equipment and experienced operatives to safely carry out the works at height.
Location: South Wales
Service Area: Swansea, Cardiff, Neath, Port Talbot & surrounding areas
Scope of Works:
Cleaning of 960 commercial solar panels
Clearance of 400 metres of roof gutters
Working at height using fall arrest harness systems
Access via 37-metre truck-mounted cherry picker
The Challenge
Commercial properties across Swansea and South Wales often face issues with reduced solar efficiency and blocked gutters due to coastal air, bird fouling, and airborne debris.
Key challenges on this site included:
A large solar panel array spread across multiple roof sections
High-level access requirements and strict working-at-height regulations
Over 400 metres of commercial guttering needing clearance
Completing the works with minimal disruption to the client’s operations
Our Local Approach
1. Site Survey & Safety Planning (South Wales)
As a trusted provider of commercial roof maintenance in South Wales, we carried out a full site survey and risk assessment prior to starting work. This ensured safe access for both roof and MEWP operations.
All operatives were fully trained in:
Working at height
Fall arrest harness systems
IPAF-certified cherry picker operation
2. Commercial Solar Panel Cleaning – 960 Panels
The solar panels were cleaned using pure water-fed systems designed specifically for commercial solar panel cleaning in Swansea and South Wales.
Benefits for local businesses:
Improved solar efficiency and energy output
No harsh chemicals – environmentally friendly and compliant
Safe for long-term panel performance
Ideal for large-scale commercial solar installations
This method is particularly effective for properties exposed to coastal conditions common in Swansea, Neath and Port Talbot.

3. Gutter Clearance – 400 Metres
Blocked gutters are a common issue for commercial buildings across South Wales, especially during autumn and winter months.
Our team completed:
Full commercial gutter clearance in Swansea
Manual removal of debris while secured in fall arrest harnesses
High-level access using a 37m truck-mounted cherry picker
Safe waste disposal and final flow checks
This reduced the risk of water ingress, leaks, and structural damage.


Access Equipment & Safety Measures
Fall arrest harness systems for roof works
37-metre truck-mounted cherry picker for high-level access
Ground exclusion zones to protect staff and the public
On-site supervision throughout the project
We operate in full compliance with UK health and safety regulations across all South Wales sites.

Results
✔ 960 solar panels cleaned across a commercial South Wales site
✔ 400 metres of gutters cleared and fully operational
✔ Improved solar performance potential
✔ Reduced risk of overflow and water damage
✔ Works completed safely, on time, and to specification

Why Commercial Properties in Swansea & South Wales Need Regular Maintenance
Dirty solar panels can lose up to 30% efficiency
Coastal pollution and bird fouling are common in Swansea and Mumbles
Blocked gutters can cause long-term building damage
Planned maintenance supports compliance and asset protection
Conclusion
This case study demonstrates our expertise in commercial solar panel cleaning and gutter clearance in South Wales. Using specialist equipment and trained operatives, we deliver safe, efficient, and reliable results for commercial and industrial clients.
Google Review – 2026
‘Andrew and the team at One Stop were chosen to clean the gutters on our industrial units along with 960 solar panels. The work was carried out to the highest standard with minimal fuss. Everything was taken care of, unlike other companies that required us to hire the articulated boom and skips?
Without a second thought I would recommend Andrew to anyone requiring an industrial / domestic cleaning company’
