Introduction:
Harnessing the power of the sun requires keeping your solar panels in top shape. While they silently convert sunlight into energy, they face a silent enemy: soiling. This build-up of dirt, debris, and organic matter can significantly impact their efficiency.
This blog post explores the five biggest soiling challenges for solar panels in the UK and provides tips for maintaining optimal performance.
Myth vs. Reality of Solar Panel Cleaning:
- Myth: Rain keeps panels clean.
- Reality: Rainwater can leave residue, reducing efficiency.
- Myth: Cleaning is simple.
- Reality: It requires a delicate touch to avoid damage.
Following the manufacturer’s guidelines is crucial.
Each solar panel is unique, so refer to the manufacturer’s instructions for cleaning methods, frequency, and approved materials. This ensures optimal performance and avoids voiding warranties.
Top 5 Soiling Challenges:
Lichens:
- Green or white patches that adhere to the surface.
- Thrive in humid environments, blocking sunlight and promoting moisture.
- Cleaning Tip: Use specialised techniques to avoid damaging the panel surface
Fungi:
- Dark, reddish, or discoloured spots indicate growth.
- Reproduce via wind-carried spores, covering large areas if left untreated.
- Cleaning Tip: Careful cleaning is needed to prevent re-growth and protect the panel’s surface.
Cement Dust:
- Fine particles that settle and become difficult to remove.
- Develop an electrostatic charge, making them cling more strongly.
- Cleaning Tip: Cleaning strategies must consider abrasiveness to avoid scratching. Consider using a specific agent for cured cement particles.
Bird Droppings:
- Uric acid content can corrode and damage panels if not removed promptly.
- Cleaning Tip: Quick and thorough cleaning is crucial, potentially requiring specialised solutions. Consider bird deterrents for persistent issues.
Dust & Environmental Pollution:
- A thin layer of airborne particles that reduces sunlight absorption.
- Cleaning Tip: Regular and thorough cleaning is essential, but avoid harsh chemicals or high-pressure techniques that could damage panels.
Cleaning Tips for Optimal Performance:
- Regular Cleaning Schedule: Maintain consistent cleaning to prevent buildup and ensure easier removal.
- Cleaning Solutions: Use solar-module-friendly solutions like Chemitek Solar’s range, certified by reputable labs like TÜV Sud.
- Professional Cleaning Services: Consider professional services for heavily soiled panels or if unsure about the best approach.
- Anti-soiling Coatings: Apply protective coatings like ChemiTek’s ASA or D-Solar to create a barrier against contaminants.
- Safe Cleaning Techniques: Opt for low-pressure methods, cleaning robots, or soft bristle brushes. Avoid high-pressure water jets, abrasive materials, or harsh chemicals.
