Solar street light system is a set of independent distributed power supply system. It is not subject to regional restriction and not affected by power installation location. Solar street light system also do not need to do excavation of the road to wiring buried pipe. Not needing power transmission and transformation system, the site construction and installation is very convenient to realize both environmental protection and energy saving. It also get better comprehensive economic benefit. It may get very convenient that adding the solar street light to divided road. Especially applying in the far away from the grid road lights, outdoor billboards, bus platform, the economic benefit may be more obvious.
Solar street lamps use single crystal or polycrystalline silicon solar module to generate electrical energy, solar battery to store electrical energy and efficient LED lamp to lighting. The solar street light adopts advanced intelligent charge and discharge controller which has the reliable properties, high luminous efficiency and high brightness. The using of dc power supply is safe ,reliable, energy saving, economical and practical and long service life. It has easy installation,without laying cable wire, no need for ac electric energy and electricity,saving national energy.
