Analysis of Carbon Reduction in Solar Film Photovoltaic Transformation of Urban Large River Crossing Channels

隧道遮光棚通过太阳能薄膜光伏改造可有效解决城市大型过江通道照明系统高耗能问题,实现隧道照明用能的绿色低碳化。本文以顺德水道过江通道为例,计算了隧道照明需求、太阳能薄膜光伏系统供电能力及光伏改造后节能低碳效果,发现隧道口遮光棚光伏全年发电量可以满足隧道照明系统全年所需用电量,每年节约标准煤35.77~39.01吨、减少碳排放68.71~74.92吨、节约运行成本8.59万~9.37万元。因此,城市大型过江通道遮光棚太阳能薄膜光伏改造具有很好的可推广性。

The tunnel shading shed can effectively solve the problem of high energy consumption in urban large-scale river passage lighting systems through solar film photovoltaic transformation,achieving green and low-carbon energy consumption for tunnel lighting.This article takes the Shunde Waterway as an example to calculate the tunnel lighting demand,the power supply capacity of the solar thin film photovoltaic system,and the energy-saving and low-carbon effects after photovoltaic transformation.It was found that the annual photovoltaic power generation of the tunnel entrance shading shed can meet the annual electricity consumption of the tunnel lighting system,and can save 35.77~39.01 tons of standard coal,reduce carbon emissions by 68.71~74.92 tons,and bring economic benefits of 85.9~93.7 thousand yuan per year.Therefore,the solar thin film photovoltaic renovation of large urban river passage shading sheds has good scalability.
