屋(wu)頂面積及(ji)周邊環境具有可(ke)行性

安裝(zhuang)(zhuang)在屋(wu)(wu)頂(ding)的太陽能(neng)發(fa)電(dian)系統(tong)是(shi)由太陽能(neng)電(dian)池板、支架以及逆變器(qi)組(zu)成，其中太陽能(neng)電(dian)池板一般都是(shi)1650CM*99CM的大小(xiao)，因此以正常5kW裝(zhuang)(zhuang)機容量(liang)的電(dian)站為例(li)，電(dian)池板數量(liang)大約為20片(pian)左右(you)，要求(qiu)的屋(wu)(wu)頂(ding)面積需要35平方米左右(you)，如果遇到老虎窗很(hen)多或者(zhe)屋(wu)(wu)頂(ding)被占用面積很(hen)大，則無法安裝(zhuang)(zhuang)容量(liang)足(zu)夠家庭使用的太陽能(neng)發(fa)電(dian)系統(tong)。而別墅一般面積較(jiao)大，屋(wu)(wu)頂(ding)面積安裝(zhuang)(zhuang)5kW——10kW是(shi)足(zu)夠的，甚至更大。

對于家(jia)庭光伏發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統而言，其(qi)并網(wang)(wang)也(ye)特(te)別(bie)容易(yi)，只要出具產權(quan)證明，離網(wang)(wang)光伏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站，確(que)保有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)安(an)裝的(de)(de)計量電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)表，即可(ke)(ke)免(mian)費(fei)申請(qing)分布式光伏發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)。同時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)公司免(mian)費(fei)提(ti)供兩(liang)塊電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)表、免(mian)費(fei)接(jie)入(ru)設計；安(an)裝也(ye)不(bu)(bu)需要特(te)殊的(de)(de)接(jie)入(ru)設備(bei)(bei)：并網(wang)(wang)開關，符合國家(jia)要求的(de)(de)組(zu)件，逆變器(qi)即可(ke)(ke)。利用固(gu)定建筑物屋頂、墻面(mian)及附(fu)屬場所建設的(de)(de)光伏發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)項目以及全部自發(fa)自用的(de)(de)地面(mian)光伏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站項目不(bu)(bu)受年度規模限制，各地區可(ke)(ke)隨時(shi)受理項目備(bei)(bei)案(an)，項目投產后即納入(ru)國家(jia)可(ke)(ke)再(zai)生(sheng)能源發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)補貼范圍。

太陽能發電：

屋(wu)頂上的(de)組件可以(yi)很好的(de)降低(di)室內溫度，特別是(shi)在(zai)(zai)夏天，通過光(guang)伏電(dian)(dian)池板將光(guang)能轉成(cheng)了電(dian)(dian)能，光(guang)伏板相當于隔熱(re)層，實測(ce)可以(yi)降低(di)3-5度的(de)室內溫度，在(zai)(zai)冬天的(de)時候也可以(yi)有效的(de)保暖。注(zhu)意施(shi)工和后續(xu)安(an)全(quan)。在(zai)(zai)別墅上施(shi)工光(guang)伏電(dian)(dian)站，有較多(duo)不可控的(de)因素(su)，應該充(chong)分考慮到施(shi)工人員的(de)安(an)全(quan)。后續(xu)業主也應該每年(nian)定(ding)期(qi)維(wei)護檢查，保證光(guang)伏發(fa)電(dian)(dian)的(de)收益率化，還有電(dian)(dian)站的(de)安(an)全(quan)。
