Solar Farm Cleaning
Solar Farm Cleaning Services
Maintaining peak performance across a solar farm requires regular, professional cleaning. Over time, dust, pollen, and debris can build up on panels, reducing their efficiency and overall energy output.
Our solar farm cleaning services are designed to maximise generation and protect your investment, using eco-friendly, non-abrasive methods and specialised equipment to ensure a safe, thorough clean every time.
Whether your site is large or small, we tailor our services to your exact needs — keeping your panels clean, efficient, and fully compliant with industry standards.
Contact our team today to schedule a professional clean and keep your solar farm performing at its best.
Our Professional Solar Farm Cleaning Process
Our expert technicians follow a detailed, step-by-step process to ensure every solar farm clean is safe, efficient, and delivers measurable results.
1. Site Assessment
We begin with a comprehensive inspection of the solar farm, assessing panel layout, tilt angle, soiling levels, water access, and site conditions. This allows us to determine the most effective cleaning method and schedule.
3. Surface Preparation
Loose debris such as leaves, twigs, and bird nests are carefully removed using soft, non-abrasive tools to protect the glass surface and frame integrity.
2. Safety Preparation
Before work begins, all safety protocols are put in place. This includes isolating electrical components where required, using full PPE, and adhering to site-specific risk assessments and health and safety standards.
4. Cleaning Techniques
Depending on the site size and conditions, we use a variety of cleaning techniques.
5. Final Inspection
After cleaning, we carry out a full visual inspection to ensure every panel is spotless and check for signs of damage, shading, or wear.
Each project concludes with a detailed report outlining the work completed, findings from inspections, and tailored recommendations for future cleaning intervals based on site conditions.
As part of our service, we also offer thermal imaging diagnostics to detect early faults, potential fire hazards, or long-term degradation.
This professional, data-driven approach helps extend the lifespan of your solar farm, maximise generation, and reduce long-term maintenance costs.
How to Know When Your Solar Panels Need Cleaning
Not sure if it’s time to schedule a clean? There are a few clear signs that your solar panels may need professional attention.
You might notice a drop in energy production, visible dust, bird droppings, or grime buildup, or shaded areas on certain panels.
If your system includes monitoring software, a gradual decline in performance or uneven output between strings often indicates soiling that’s blocking sunlight and reducing efficiency.
Regular inspections and timely cleaning help maintain consistent output and prevent long-term wear on your system.
How Often Should Solar Farms Be Cleaned?
The ideal cleaning frequency depends on your site’s location, climate, and surrounding environment.
In most cases, solar farms benefit from 1–4 professional cleans per year, but sites near farmland, industrial zones, or dusty areas may require more frequent maintenance to maintain peak performance.
To make upkeep simple, we offer scheduled cleaning and maintenance packages keeping your system efficient and worry-free all year round.
We know compliance isn’t the most exciting topic — but it’s what keeps every project safe, professional, and fully above board.
