Solar Street Light
The solar street lighting system is a stand-alone widely-distributed power suppply system without geographical restrictions. not to be impacted by the location of their electrical installation and without any need for excavation of road for wire layout construction and it is convenient in site construction and installation without any need for power transmission or transformation systems, which is environmental protection friendly. energy-saving. good in comprehensive economic benefits. particularly convenient for finished roads to add solar street lights. In particular. for those street lights, outdoor billboards, bus platform applications on the roads far away from the grid, their economic benefits are all the more obvious.
The solar panel generates current when sunlight hit the cells which are welded in different series and parallel according to 12V or 24V system requirement .Current will charge battery through solar controller which preset with protection function of over charge and over discharge, working duration time for LED lamp.
When darkness comes, voltage of solar panel will drop down which triggers the solar controller open circuit to discharge, and that makes LED lamp turn on.
How to configure a suitable solar street lights
As solar radiation and rainy season varies largely around the world. There are factors determine system configuration.
- Installation country or city, for example, Dubai, solar panel will be calculated based on solar radiation in this city from data of NASA.
- Average consecutive rainy days, for example, most common rainy days consecutively is 3 days, which means rainy or cloudy for three days in a row. It determines battery capacity for backup during the low efficient charging days.
- Road width and distance or area that will install lights. For example, a 6 meter width road with 5km length.
- Illuminance requirement, for example, 20 lux on ground center.
