Solar Street Lighting
Solar Street Lighting is alternative to conventional street lighting and uses LED lights to replace LPS, HPS or MH lights. It utilizes solar energy through solar panels installed on poles to save electricity from grid. Solar streets lights can be totally off-grid with battery backup or can be installed with grid to use solar energy stored in batteries as well as grid electricity. In both ways, it saves electricity costs and provides environment friendly, energy efficient and cost effective solution.
Solar energy from panels is stored in batteries at day time which lights up the LED lights at nights. The height of the pole can be from 15 to 22 ft. The system comprises of solar panels, LED street lights, LED light driver, battery bank and charge controller. Technological advancement in LED illumination provides multitude advancement over conventional incandescent lights.
The system is dependent upon following factors:
- Availability of grid
- Average local sunshine hours
- Working time of the solar street lights during night
- Backup days of the system during rainy days
The system can be used in residential areas, roads, parks and other places.
