The Feasibility Analysis of “Ecological Photovoltaics” from Coal Gangue Mountains

Coal gangue is a byproduct of coal mining, and has been piled up for years in China, forming thousands hills, which have become an important part abandoned mining areas. In recent years, the government issued various policies on ecological restoration hills provided economic support. However, relying solely support not long-term solution. The key to improve production efficiency promote their sustainable development. This paper conducts on-site investigations makes proposals from perspective ecology benefits. Firstly, it suitable install photovoltaics especially those located far residential areas, with convenient transportation maintenance orientation mountain. Secondly, based preliminary design scheme laying photovoltaic cells slopes developing platforms through planting proposed. feasibility explored by constructing net present value calculation. results show that use slope only conducive development, but also can cover daily costs hill produce certain With expansion scale improvement location conditions, benefits will increase.
