Solar street lights mainly are composed of light source, controller, light pole, storage batteries and solar panel module which are connected by the wires, and some other accessories. Solar Street Light (DG-SLF-A2), with two panels, will support a stronger light power to illuminate larger areas. Thus it is ideal for street lighting, sidewalk lighting, park lighting, campus lighting, farm & ranch lighting, wildlife area lighting...

LED wattage is equivalent to approximately half the wattage of high pressure sodium light. Controller: over8 years of typical operating life, with a 2-year warranty, automatic operation from dusk to dawn or timed ON/OFF operation Pole: up to 25 years of long life time Battery: 5 7 years of maximum life, with a 2-year warranty Function & Features Environmental-friendly and Energy-Saving: With sunlight as energy source, Solar PV luminaires convert the solar energy into electrical energy then into light when needed. Safety: Most of solar lights is a low-voltage direct-current (≤ 24V) independent power system, its voltage is lower than the human’s security voltage, comply with the national standards for safe use of electricity. Easy to Installation: No need to lay electric cables, install and maintain simply and conveniently.
