烟台(tai)光(guang)伏(fu)(fu)发(fa)电系统(tong)在(zai)设计(ji)之前，需要(yao)了解并获取一些进(jin)行计(ji)算(suan)和(he)设备选择所(suo)需的(de)(de)基本(ben)数(shu)据：如光(guang)伏(fu)(fu)发(fa)电系统(tong)安装的(de)(de)地理位置(zhi)，包括地点、纬度、经(jing)度和(he)海拔；该地区的(de)(de)气(qi)象(xiang)资料，包括逐(zhu)月的(de)(de)太阳能总辐(fu)射(she)量(liang)、直接辐(fu)射(she)量(liang)以及(ji)(ji)散射(she)辐(fu)射(she)量(liang)，年平均气(qi)温高、低气(qi)温。长(zhang)连续阴雨天(tian)数(shu)，大风速以及(ji)(ji)冰雹、降雪等(deng)特殊气(qi)象(xiang)情(qing)况(kuang)等(deng)。要(yao)求所(suo)设计(ji)的(de)(de)光(guang)伏(fu)(fu)发(fa)电系统(tong)具有先进(jin)性(xing)、完整性(xing)、可扩(kuo)展性(xing)、智(zhi)能化程度高，以保(bao)证系统(tong)安全性(xing)、可靠性(xing)和(he)经(jing)济性(xing)。
(1)先(xian)进性。随着国家对于可再(zai)生能(neng)源的(de)日(ri)益(yi)重视，开发(fa)(fa)利用(yong)(yong)可再(zai)生能(neng)源已(yi)经是(shi)新能(neng)源战略的(de)发(fa)(fa)展趋势。根(gen)据(ju)太阳(yang)日(ri)照条(tiao)件、电(dian)源设(she)施(shi)及(ji)用(yong)(yong)电(dian)负(fu)载的(de)特性，选(xuan)择利用(yong)(yong)太阳(yang)能(neng)资(zi)源建设(she)烟台光伏发(fa)(fa)电(dian)系统，既节能(neng)环保，又能(neng)避免采用(yong)(yong)市电(dian)铺设(she)电(dian)缆的(de)巨大(da)投(tou)资(zi)，是(shi)具有(you)先(xian)进性的(de)电(dian)源建设(she)方案(an)。
(2)完(wan)整性(xing)(xing)。太阳(yang)能光(guang)伏(fu)发(fa)电(dian)(dian)(dian)(dian)系(xi)(xi)(xi)统(tong)(tong)(tong)包括：太阳(yang)能电(dian)(dian)(dian)(dian)池组件、蓄(xu)电(dian)(dian)(dian)(dian)池、控制器(qi)、逆(ni)变器(qi)等部件。光(guang)伏(fu)发(fa)电(dian)(dian)(dian)(dian)系(xi)(xi)(xi)统(tong)(tong)(tong)可以独立对外(wai)界提供电(dian)(dian)(dian)(dian)源，也可与其他用电(dian)(dian)(dian)(dian)负载(zai)和市电(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)源配套，形成一(yi)个完(wan)整的(de)离网(wang)和并(bing)网(wang)的(de)光(guang)伏(fu)发(fa)电(dian)(dian)(dian)(dian)系(xi)(xi)(xi)统(tong)(tong)(tong)。光(guang)伏(fu)发(fa)电(dian)(dian)(dian)(dian)系(xi)(xi)(xi)统(tong)(tong)(tong)应(ying)具有完(wan)善的(de)控制系(xi)(xi)(xi)统(tong)(tong)(tong)、蓄(xu)能系(xi)(xi)(xi)统(tong)(tong)(tong)、功率变换系(xi)(xi)(xi)统(tong)(tong)(tong)、防雷接地系(xi)(xi)(xi)统(tong)(tong)(tong)等构成一(yi)个统(tong)(tong)(tong)一(yi)的(de)整体，具有完(wan)整性(xing)(xing)。
(3)可扩展性。随着太(tai)阳能(neng)光伏(fu)发(fa)(fa)电技术的快速发(fa)(fa)展，光伏(fu)发(fa)(fa)电系统的功能(neng)也会越(yue)来越(yue)强大(da)。这就要(yao)求烟台光伏(fu)发(fa)(fa)电系统能(neng)适应系统的扩充和升级。
