Shanghai elevated both sides of the noise barrier can generate electricity when the night lights

Shanghai elevated both sides of the long sound barrier, in addition to sound insulation, but also hope to increase the power generation function. Reporters learned yesterday, a section of 70 meters long with solar photovoltaic power generation device has been put into trial operation of the sound barrier, the use of storage battery storage power during the day, the evening supply of LED lighting.

This pilot solar photovoltaic power generation noise barrier set up in the outer ring Tongji Road overpass. Technical personnel in Shanghai Shanghai and Hong Kong Construction Development Company Limited, told reporters that the power "mystery" is that the outer side of the upper end of the noise barrier, every 2 meters installed a set of solar photovoltaic devices, each with 60 watts of power, photovoltaic device test section length of 70 meters of the total power of about 2000 Watts, the annual "green electricity" about 2500 degrees, equivalent to 2250 kilograms of carbon dioxide emissions per year.
