Most homeowners choose solar power to reduce electricity bills, but one persistent issue affects overall performance: solar panel cleaning. In India, dust, pollution, and hard water make cleaning difficult and increase solar maintenance requirements. Because manual cleaning is irregular and inefficient, solar panels often fail to deliver their maximum output.
Freyr Energy introduces India’s First self-cleaning solar panel system, a breakthrough technology that automates the entire cleaning process. It ensures consistent cleaning, dependable performance, and higher long-term savings, making it a true zero-maintenance solar solution.
What Is a Self-Cleaning Rooftop Solar System?
A self-cleaning solar system automatically washes panels without manual effort. Key features include:
- Timer-enabled automatic cleaning
- Highly water-efficient technology
- Automated cleaning cycles
- 90% lower water usage
- Up to 5% higher solar energy generation
This advanced setup keeps panels clean throughout the year with almost zero intervention.
Why Traditional Solar Panels Need High Maintenance
Dust, Pollution & Hard Water Stains
- Indian rooftops accumulate dust quickly, reducing solar output.
- Hard water leaves mineral stains that block sunlight.
- These issues demand frequent cleaning to maintain efficiency.
Challenges of Manual Cleaning
- Cleaning during peak summer is unsafe due to extreme heat.
- Monsoon seasons make rooftops slippery and risky.
- Manual washing needs labour and large amounts of water, increasing costs.
Efficiency Loss Due to Dust
- Even a thin dust layer can reduce output by 5–20%.
- Irregular cleaning decreases overall performance.
- Manual cleaning cannot ensure consistent long-term results.
