As a leading supplier of solar powered street lights, we understand that efficient performance of the lights over time is crucial to your operations. Today, I want to share with you the performance and maintenance costs of street lights the way we automate maintenance – clean them.
1.Dust accumulation: solar street lights' "silent killer"
The solar panels’ efficacy determines the brightness and stability of street lights. However, panels are outdoors; hence exposed to dust, bird droppings, sand, and industrial dust, all of which gradually cover the surface. Research indicates:
Mild dust accumulation (not cleaned for 3 months) can reduce power generation efficiency by 15-25%
Severe pollution (more than 6 months) may cause power generation to drop by more than 40%
This means that street lights that appear to be in normal use may be operating at less than 60% efficiency, resulting in shortened lighting time or insufficient brightness.efficiency.
2. Drawbacks of conventional cleaning approaches
The majority of street lamps today accepted manual cleaning. The disadvantages are apparent.
Specialized high-altitude cleaners and their equipment order costs hundreds of yuan per lamp for cleaning.
High-altitude work is risky, particularly, in busy traffic zones.
Budget limitations mean that most street lamps are cleaned only one to two times a year, leading most street lamps to become neglected.
Manual removal is unable to guarantee that every panel has been cleaned, leading to inadequate cleaning results.
3.Technical innovations of automated cleaning system
Through creative system automation, our solutions address these concerns:
Intelligent cleaning system
with dust sensors to measure CPT to pollution levels, responds to preset parameters autonomously.
Cleans only after preset environmental conditions have been met.
Effective cleaning mechanism
Non-contact airflow cleaning technology prevents scouring the surface.
Micro-rotating brushes with cleaning liquid dope to eradicate stubborn stains equipped.
Economy and practicality in the operation mode
Powered by the sun: no additional energy costs.
Easy to fix: modular design.
4.Practical advantages of automatic cleaning
Raise energy productivity
Maintain the panel at over 95%.Raise the power creation productivity and guarantee stable lighting of street lights all night long
Extremely bring down support costs
Save 60-80% on cleaning and maintenance expenses.Save money on indirect expenses like upkeep traffic control.
Extend equipment life
Regular automatic cleaning can preclude long-term adhesion of corrosive materials and extend the life span of solar panels by over 30%.
Improves safety
It fully evades the peril of high-altitude operations, especially fitting for hazardous zones such as highways and bridges.
Which projects need automated cleaning the most?
City main roads and lifted road lighting Industrial parks and ports lighting Deserts, shores, and other windy sandy places Far areas where frequent care is hard
Conclusion
Over the twenty-year lifespan of solar street lights, an automated cleaning system will not only ensure stable lighting effects but also save much on maintenance costs.
We recommend considering integrating automatic cleaning functions in the design phase for new projects to get the best return on investment. For more technical details or customized solutions, please feel free to contact our technical team.
