Feasibility Analysis on Application of Photovoltaic Sound Barriers in Urban Expressway
Combined with the Shijiazhuang Huai'an Road Viaduct West Extension Project,under two schemes of conventional components and color components of photovoltaic sound barriers,the electrical system,power generation,full life cycle cost and benefit of the off-grid system and the grid-connected system are studied respectively,and the feasibility analysis is carried out.The conclusion shows that under the condition that the cost of energy storage devices cannot be significantly reduced,and it is economically infeasible to use the photovoltaic sound barriers under the off-grid systems for lightning.The photovoltaic sound barriers of colored components will affect the power generation efficiency.At the same time,the cost is higher,which is economically infeasible.The conventional components of photovoltaic sound barriers are economically feasible and have certain social benefits under grid-connected systems.
