Solar Street Light Power Solutions
ElectroWorld Lucknow Solar LED Street lighting system are approved for their high efficiency, long lasting performance and it make significant contribution to the energy saving. It is a perfect solution for the street lighting in areas where street main is unavailable as it switches off automatically. These lights generally installed in wide roads, railway junction and industrial areas. Street light with inbuilt charge controller enables dusk to dawn operation. This system consists of solar panels, batteries and the street lamp and are designed to work throughout the night.

Salient Features:
Most solar panels turn on and turn off automatically by sensing outdoor light using a light source. Solar LED Street Light System are designed to work throughout the night. Many can stay lit for more than one night if the sun is not available for a couple of days. Older models included lamps that were not fluorescent or LED. Solar lights installed in windy regions are generally equipped with flat panels to better cope with the winds.
Latest designs use wireless technology and fuzzy control theory for battery management. The street lights using this technology can operate as a network with each light having the capability of performing on or off the network.[1]
ComponentsSolar powered street lightsSolar street lights consist of 5 main parts:
Solar PanelSolar panel is one of the most important parts of solar street lights, as solar panel will convert solar energy into electricity. There are 2 types of solar panel: mono-crystalline and poly-crystalline. Conversion rate of mono-crystalline solar panel is much higher than poly-crystalline.
Lighting FixtureLED is usually used as lighting source of modern solar street light, as the LED will provide much higher Lumens with lower energy consumption. The energy consumption of LED fixture is at least 50% lower than HPS fixture which is widely used as lighting source in Traditional street lights. LEDs lack of warm up time also allows for use of motion detectors for additional efficiency gains.
Rechargeable BatteryBattery will store the electricity from solar panel during the day and provide energy to the fixture during night. The life cycle of the battery is very important to the lifetime of the light and the capacity of the battery will affect the backup days of the lights. There are usually 2 types of batteries: Gel Cell Deep Cycle Battery and Lead Acid Battery.
ControllerController is also very important for solar street light. A controller will usually decide to switch on /off charging and lighting. Some modern controllers are programmable so that user can decide the appropriate chance of charging, lighting and dimming.
PoleStrong Poles are necessary to all street lights, especially to solar street lights as there are components mounted on the top of the pole: Fixtures, Panels and sometime batteries. And wind resistance should also be taken into consideration when choosing the pole.
TypesSolar street light at the bus stopEach street light can have its own photo voltaic panel, independent of other street lights. Alternately, a number of panels can be installed as a central power source on a separate location and supply power to a number of street lights.[2]

Advantages
- Solar street lights are independent of the utility grid. Hence, the operation costs are minimized.
- Solar street lights require much less maintenance compared to conventional street lights.
- Since external wires are eliminated, risk of accidents is minimized.[2]
- This is a non polluting source of electricity
- Separate parts of solar system can be easily carried to the remote areas
- Initial investment is higher compared to conventional street lights.
- Risk of theft is higher as equipment costs are comparatively higher.[2]
- Snow or dust, combined with moisture can accumulate on horizontal PV-panels and reduce or even stop energy production.
- Rechargeable batteries will need to be replaced several times over the lifetime of the fixtures adding to the total lifetime cost of the light.

The operation is very simple. The solar energy is converted to electrical energy by the SPV module and stored in a sealed maintenance-free (SMF) battery. During charging, green light on charge controller will be continuously ON. After battery is full charged, green light will blink. At night, when solar panel voltage drops, luminary will be automatically switched ON & in the morning, when solar panel voltage increases, luminary will be automatically switched OFF. Therefore, it is ideal for remote/ inaccessible areas.
