1.Brief of Solar 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. System Composing of Solar Light
Solar Panel: Multi crystalline silicon or mono-crystalline silicon solar cells, 20W- 300W, life time 25 years
System Controller:
The controller detects day and night using the PV array. An entirely new feature is the integrated clock that sets itself automatically based on the levels of brightness detected during a 24 hour day.
Features:
PWM shunt battery charging,
state of charge (SOC) battery regulation,
automatic selection of voltage (12 V / 24 V),
temperature compensation,
Electronic Protections:
high voltage disconnect (HVD),
low voltage disconnect (LVD),
deep of discharge disconnection (DOD),
reverse polarity of solar modules,
reverse polarity of load & battery,
Storage Battery:
Maintenance-Free,
Material: Lead Acid or Gel selected,
Life time:Lead Acid 5years/Gel 8~12 years,
Operating Temperature-35~50°C,
Excellent seal characteristic,
large capacity and superior resisting,
over discharge capability,
The lowest self-discharge rate,
Flexible installation,
Specification 12V/4AH,12AH,17AH,24AH,38AH,65AH,120AH,150AH,200AH
Pole and Support Structure
All components are made of steel, galvanizing(Support Structure with electro galvanizing,Flange and Pole with hot galvanizing) ,plastic-coated wind-resistance>40m/S
lamps and lanterns
LED (Light-Emitting Diode) is the most advanced lamp now, be made from semiconductor radiant material. Such as fluorescence, incandescence, and sodium lamps etc. will be replaced in the coming several ten years.
Power consumption,12V/24V from10W to 300W,
irradiance angle 120°,
Long life 30,000h,
Few attenuation,no pollution,

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