High Efficiency Solar Street Lighting System
1. Brief of Solar Street Light
Background: The requirement of energy source is increasing rapidly in the world, but traditional source like oil, coal etc. can’t regenerate any more, therefore, solar energy as a kind of renewable and green energy will become more important gradually. In recent years, solar lighting is popularly used all over the global.
Operating principle: Solar panel produce electricity and charge to battery during daylight,The lamp-house get power from battery to light at night. The whole process is finished by system itself, does not need any maintenance and other power supply
Summarize: Solar light bring shine to people in darkness and get green power from the sun, Operating with high reliability,security and free maintenance
2. Solar Street Lighting System Configuration (SSL100)

3. Comparison between Solar Street Light and Traditional Street Light Which Powered from Grid:
Item | Solar Street Light |
Installation | Easy to install, does not need trenching ,extending wire from electricity grid, laying tube. only a cement groundwork should be built.
|
Maintenance | Does not need any payment for power; free maintenance for power system
|
Security | Operating with low voltage 12VDC or 24VDC, High security, No hidden trouble of safety |
Green Power | Renewable energy; Just pay at beginning, than benefit from the sun in long term |
Item | Traditional Street Light |
Installation | Installation is complex and difficult. must to extend wire from grid, lay tube, pull on cables through tube, backfill the sap. Wire is easily be destroyed when rebuilding the road or other project.
|
Maintenance | Must to payment for high cost of electricity and repair. |
Security | Operating with AC voltage 220~240V, its danger voltage for people, other construction near street light may affect street light operating |
Green Power | Power from general grid, can’t regenerate |
