                              光伏电站选型设计两个经济平衡点
                              2018-11-07

                                光伏前期项目开发完成后,开始进入设计和实施阶段。随着国家政策的变化,中大型地面电站补贴逐渐减少,将进入平价上网或者低价上网阶段,光伏系统的设计,对成本的控制要求更高。目前光伏系统对成本和效率的控制有两种路线,一是高效组件路线,采用大功率组件,减少支架和人工的费用;二是组件超配路线,提高组件和逆变器的比例,让逆变器尽量满功率输出,减少逆变器及交流电缆、配电柜、升压变的费用。两种方案各有优势,但都不是绝对的,需要综合考虑,精心计算,找到一个经济平衡点。
