解题方法
6 . 使太阳光射到硅材料上产生电流直接发电,以硅材料的应用开发形成的光电转换产业链条称之为“光伏产业”.某农产品加工合作社每年消耗电费
万元.为了节约成本,决定修建一个可使用
年的光伏电站,并入该合作社的电网.修建光伏电站的费用(单位:万元)与光伏电站的太阳能面板的面积
(单位:
)成正比,比例系数为
.为了保证正常用电,修建后采用光伏电能和常规电能互补的供电模式用电,设在此模式下.当光伏电站的太阳能面板的面积为
(单位:
)时,该合作社每年消耗的电费为
(单位:万元,
为常数).记该合作社修建光伏电站的费用与
年所消耗的电费之和为
(单位:万元).
(1)求常数
的值,并用
表示
;
(2)该合作社应修建多大面积的太阳能面板,可使
最小?并求出最小值.
(3)要使
不超过
万元,求
的取值范围.
