solar street light /solar led light Introduction to solar street lights: Solar street lights are solar street lighting systems which can save energy, environment friendly, convenient to install. Solar street lights are powered by monocrystalline or polycrystalline solar panels which convert the solar energy into electricity saved in the storage batteries without maintenance. Solar street lights are controlled by control systems to keep storage batteries from over-charging and over-discharging. Solar street lights automatically turn off at daytime with light sensor and turn on at night after a full day's charge, stable and safe in capability. Lead-Acid Storage batteries Free Maintenance and gel batteries are usually used to solar street lighting systems. There're lots of light sources for solar street lights such as: Low-pressure sodium lights, High-pressure sodium lights, metal halide lights, electrode lights, energy-saving lights, LED lights...LED lights are more and more popular now. Voltage of solar street lights is often DC12V or DC24V. Solar street lights Description The basic components of solar street lights: Solar panels Storage batteries: Gel batteries or Lead-Acid Storage batteries free maintenance Controllers: Solar Street lights controller system.
