Achieving carbon neutrality means that enterprises, products, or individuals who produce carbon dioxide emissions within a certain period of time, through energy saving and emission reduction, etc., offset the carbon dioxide emissions they produce and achieve near zero carbon dioxide emissions. The development of solar LED street light is an important way to save energy and reduce emissions. Solar street light is pollution-free, radiation-free and green, bringing environmentally sustainable advantages to the construction of municipal projects. The use of solar street lights can make streets and communities truly green and zero energy.
