曾经媒体报道过各地有个人用户尝鲜光伏电站卖电赚钱的新闻。一个5千瓦的电站,一年可卖电4000多块,11年就可以收回成本,剩下的14年设计寿命就可以纯赚了。但是,买回的光伏组件一定能使用25年吗?从现在来看,恐怕不好说了。目前,光伏组件在使用过程中不可避免地出现功率衰减现象(发电量变少)。通常来说,光伏组件在第一年衰减5%,以后每年不超过0.8%。光伏组件企业普遍承 Once the media reported around the individual users of early adopters photovoltaic power station to make money making news. A 5-kilowatt power station can sell more than 4,000 pieces a year and can recover the cost in 11 years. The remaining 14 years of design life can be purely earned. However, the purchase of photovoltaic modules can be used for 25 years? From now on, I am afraid I’m sorry to say. At present, the PV modules inevitably appear in the use of power attenuation phenomenon (less power generation). In general, the PV module decays 5% in the first year and does not exceed 0.8% in the future. Photovoltaic module enterprises generally undertake
