        The solar light is a new type of lumination equipment. Its contains three core parts: the polysilicon panel for power supplying/the Maintenance-free valve-controlled sealed storage battery for energy storage and the LED light for light source. It controls by the Intelligent charge and discharge controller. The solar street lights operate from night until morning. The LED lamp automatically switches on after the sunset and switches off after the sunrise. This system design consists of the following parts:

  • Solar panels
  • LED light
  • Rechargeable battery
  • Controller
  • Pole
  • Interconnecting cables

Solar Panels

In solar street lights, the solar panel is one of the most important parts, and it is also known as solar photovoltaic cell. These cells are of two types: poly crystalline and mono crystalline. Compare to the poly crystalline, mono crystalline conversion rate is higher. Solar panels use light energy from the sun used to convert solar energy into electricity, which can be used to run many applications.

LED Light

In modern solar street lights, LEDs are used as lighting source and LED provide much brighter light with lower energy consumption. The energy utilization of LED fixture is lower than the HPS fixture, which is generally used in traditional street lights. Compare to the other HD lamps, and these lights do not emit light in all directions. The directional uniqueness of the LEDs will affect the design of lamps.

Rechargeable Battery

Rechargeable battery is a type of electrical battery or accumulator and its electro mechanical reactions are reversible so it is called as secondary cell. Usually, there are two types of batteries: lead acid battery and gel cell deep cycle battery.


In solar LED street lights, a controller is very important as it usually decides to switch on or switch off the lighting and charging. Some modern controllers are programmable and are used to decide a suitable chance of lighting, dimming and charging. The Controller consists of a battery charger, a secondary power supply, a Led lamp driver, a driver, a protection circuit and a MCU.


For every street light, a strong pole is necessary, especially for a solar street light, there are some components like fixtures, batteries and panels mounted on the top of the pole, and input power consumption is 7.2 watt (LED). In solar street lights, the input operating voltage is 12V DC nominal system voltage, and the light output at the height of 12 feet is min of 09 LUX (unit of luminance).

Interconnecting cables

The battery box, Led light and solar panel are all fixed on the top of the pole and they are interconnected with cables. The cable for this LED system includes a PV module to the controller, and from controller to the battery and lamps. The cable size and lengths depends on the current being carried to the lights and the height of the pole.

With assembling all the above components into a one integrated system results the complete solar LED light system which uses sunlight energy to power the LED lamps fitted on street poles.

Solar LED Street Light Applications

  • Area lighting
  • Airport lighting
  • Hospital parking
  • Parks and playground parking
  • Parking lot lighting
  • Highway road way lighting
  • Street lighting
  • Security light
  • Highway and ramp lighting
  • Bridge lighting
  • Residential lighting
  • Industrial lighting
  • Commercial lighting
