铝材在太阳能光伏发电装备中的应用

太阳能光伏发电是一种再生的无污染的新能源,挤压铝材是制造这种发电装备有竞争力的可选材料,电池板框架、支柱、支撑杆、拉杆等都可以用铝合金制造。太阳能光伏发电装备铝材可用6061、6063、6082铝合金挤压,平均铝材用量约60 t/MW,减排二氧化碳933 kt/MW。我国云南昆明石林太阳能发电站一期已于2010年5月并网发电,亚洲第一大,仅次于美国及西班牙早些时候建成的。截至2009年底,全球太阳能光伏发电系统装机容量已超过1GW。目前妨碍太阳能大发展的主要障碍是造价过高,建设成本约8 000元/kW。

Application of aluminum material in solar photovoltaic power generation equipment

The solar photovoltaic power generation is a new,recyclable and nonpolluting energy source.The aluminum alloy extrusion is the selectable and competitive material for constructing this kind of electricity generation equipment.The frame of battery panel,post,supporting rod and tie-rod can all be able to use aluminum alloy.The suitable aluminum material for making electricity solar photovoltaic generation equipment are 6061,6063 and 6082 aluminum alloy extrusions.The average consumption of the aluminum materials is about 60 ton/MW,the reduction of carbon dioxide is 933kt/MW.The first solar energy generation station located at Kunming,China,its first periodic project has been completed and combined with power transmission network in May 2010.It is the largest one in Asia,only smaller than the stations built earlier in America and Spain.By the end of 2009,the total capacity of the electricity generation system with photovoltaic solar energy in the world is more than 1GW.The main obstruction for building up and developing solar energy generation system in China now is the high cost,which is about 8000 yuan/kW(RMB).
