为什么要光伏与建筑一体化

xaoyaxiya

由于太阳能能量密度较低并且高度分散，为了提供所需的能源，必须有足够的接受面积。据测算：为了满足2000年全球电力的需求，以太阳能电池转换率10%计算，需要的面积为840km×840km=640000km2，这相当于德国和意大利两个国家的面积，太阳能电池。
　　我国1995年的发电量约为1亿MW·h，如果全部用太阳能电池发电，其接收面积约为12500km2，比天津市还要大。以上数值表明，所需的面积是相当可观的，光伏与建筑一体化有效利用建築物的外表大面積，是解决接受面积的主要途径，
　　光伏建筑一体化的系统，如幕墙光伏发电系统，成本随着建筑物的设计阶段和光伏电池与建筑装饰材料生产过程的结合程度有很大的依赖。研究表明，如果设计院、建材生产商和光伏制造商能够充分协作起来，建材光伏一体化的发电单元的制造成本与单独生产光伏组件的成本类似，甚至比建材加光伏组件的成本还低，而逆变和布线系统则可以整体并入到建筑物的电力系统中去，因此，BIPV的成本可能比单独的光伏发电还要低得多。http://www.radiantholding.com
