家用太陽能發電系統怎么樣

家用太陽能發電系統在安(an)裝的(de)(de)時候(hou)所需要(yao)使用的(de)(de)硬(ying)件(jian)(jian)包(bao)含了配電(dian)(dian)箱、光伏組件(jian)(jian)支架等，硬(ying)件(jian)(jian)的(de)(de)價格(ge)成本(ben)并(bing)不是(shi)特別便宜，并(bing)且家庭安(an)裝太(tai)(tai)陽(yang)能發(fa)電(dian)(dian)系(xi)統(tong)成本(ben)，除了和一些硬(ying)件(jian)(jian)設備有較(jiao)大(da)的(de)(de)關系(xi)，還(huan)和太(tai)(tai)陽(yang)能發(fa)電(dian)(dian)系(xi)統(tong)的(de)(de)安(an)裝容量有著較(jiao)大(da)的(de)(de)關系(xi)。一般來說平房屋頂每1000瓦需要(yao)安(an)裝面積為10平方(fang)米。按照目前太(tai)(tai)陽(yang)能發(fa)電(dian)(dian)系(xi)統(tong)行業(ye)制定的(de)(de)價格(ge)標(biao)準來計算，如果包(bao)含了系(xi)統(tong)的(de)(de)安(an)裝和售后服務5千瓦需要(yao)投資35,000元人民幣左右，10千瓦需要(yao)投資7萬元人民幣左右。

說完(wan)了家(jia)(jia)(jia)用(yong)(yong)太(tai)陽能(neng)(neng)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)(de)(de)成本之后(hou)，我們再來看一下該(gai)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)(de)(de)收(shou)益。家(jia)(jia)(jia)用(yong)(yong)太(tai)陽能(neng)(neng)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)能(neng)(neng)夠并入我們中國(guo)(guo)(guo)國(guo)(guo)(guo)家(jia)(jia)(jia)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)，而(er)(er)且可(ke)以領取相應的(de)(de)(de)補(bu)貼(tie)。家(jia)(jia)(jia)用(yong)(yong)太(tai)陽能(neng)(neng)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)并入中國(guo)(guo)(guo)國(guo)(guo)(guo)家(jia)(jia)(jia)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)模(mo)式(shi)(shi)(shi)，可(ke)以分為自(zi)發(fa)(fa)自(zi)用(yong)(yong)余(yu)額(e)(e)上(shang)網(wang)(wang)和(he)全額(e)(e)上(shang)網(wang)(wang)幾種方(fang)式(shi)(shi)(shi)，前兩(liang)種方(fang)式(shi)(shi)(shi)指(zhi)的(de)(de)(de)是(shi)自(zi)己加裝(zhuang)(zhuang)安(an)裝(zhuang)(zhuang)的(de)(de)(de)太(tai)陽能(neng)(neng)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)發(fa)(fa)出的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)量自(zi)家(jia)(jia)(jia)使用(yong)(yong)，用(yong)(yong)不完(wan)的(de)(de)(de)賣給(gei)國(guo)(guo)(guo)家(jia)(jia)(jia)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)，而(er)(er)且我們國(guo)(guo)(guo)家(jia)(jia)(jia)在目(mu)前對(dui)于這兩(liang)種模(mo)式(shi)(shi)(shi)發(fa)(fa)出的(de)(de)(de)每一度電(dian)(dian)(dian)(dian)(dian)都(dou)會給(gei)予3毛7的(de)(de)(de)補(bu)貼(tie)，持續補(bu)貼(tie)20年(nian)。全額(e)(e)上(shang)網(wang)(wang)模(mo)式(shi)(shi)(shi)指(zhi)的(de)(de)(de)是(shi)發(fa)(fa)出的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)量全部賣給(gei)國(guo)(guo)(guo)家(jia)(jia)(jia)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)價格為7毛5一度電(dian)(dian)(dian)(dian)(dian)。如果您家(jia)(jia)(jia)中安(an)裝(zhuang)(zhuang)了家(jia)(jia)(jia)用(yong)(yong)太(tai)陽能(neng)(neng)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)，采用(yong)(yong)了自(zi)發(fa)(fa)自(zi)用(yong)(yong)余(yu)額(e)(e)上(shang)網(wang)(wang)的(de)(de)(de)模(mo)式(shi)(shi)(shi)，收(shou)回成本的(de)(de)(de)時間為6.7年(nian)，選擇全額(e)(e)上(shang)網(wang)(wang)模(mo)式(shi)(shi)(shi)，收(shou)回成本需(xu)要7.7年(nian)。

家用太陽能發電系統能帶空調嗎

家用太陽能發電根據配置，發電量有大有小。按照一般情況，太陽能發電可以帶空調但(dan)不能直(zhi)接供，要(yao)先(xian)用(yong)(yong)電瓶把電儲存越來，再通(tong)過一個逆(ni)變(bian)器(qi)把直(zhi)流電變(bian)成交流電，假如功率(lv)足夠(gou)大是(shi)可以(yi)滴。如果用(yong)(yong)的(de)是(shi)調頻(pin)空調，電瓶組(zu)又有合(he)適的(de)電壓組(zu)合(he)，可以(yi)不用(yong)(yong)逆(ni)變(bian)器(qi)，可以(yi)提高整個電源的(de)效(xiao)率(lv)。但(dan)這樣要(yao)求太(tai)陽能板足夠(gou)大，否則功率(lv)不夠(gou)就(jiu)帶不動。

太陽能發電帶動空調的實例

我們還是通(tong)過一個(ge)實(shi)例來(lai)了(le)解一下太陽(yang)能發電如何帶(dai)動空調的吧。

比如一個用戶有250瓦電(dian)池板四塊(kuai)，100AH蓄電(dian)池四塊(kuai)，2000瓦工頻(pin)純正波逆變(bian)器一臺，48V30A控(kong)制器一部(bu)，這樣的搭配可(ke)以帶(dai)起(qi)1.5匹變(bian)頻(pin)空調(diao)嗎?

如果(guo)單(dan)從電(dian)(dian)(dian)功率(lv)的角度(du)計算是(shi)(shi)可以的。因為1.5p的空(kong)(kong)調(diao)的電(dian)(dian)(dian)功率(lv)大(da)也就(jiu)1kw，用(yong)戶(hu)是(shi)(shi)2kw的逆變(bian)器，因此可以給這(zhe)臺(tai)變(bian)頻空(kong)(kong)調(diao)供電(dian)(dian)(dian)。然后就(jiu)是(shi)(shi)計算電(dian)(dian)(dian)能讓空(kong)(kong)調(diao)運(yun)行多久了。用(yong)戶(hu)的4塊太陽能電(dian)(dian)(dian)池板按(an)照一天5小時的有效(xiao)光照，可以發(fa)電(dian)(dian)(dian)5kwh，就(jiu)是(shi)(shi)5度(du)電(dian)(dian)(dian)，4塊蓄電(dian)(dian)(dian)池是(shi)(shi)100Ah，那(nei)么(me)多也只(zhi)能存放5度(du)電(dian)(dian)(dian)。也就(jiu)是(shi)(shi)說，只(zhi)要用(yong)戶(hu)的空(kong)(kong)調(diao)一天耗電(dian)(dian)(dian)量不超過(guo)5度(du)電(dian)(dian)(dian)就(jiu)可以了。

再按另一個角度來考慮一下。變頻空調如果是在房間里，空間不大，隔熱保溫好，所以如果是夏天，設定的溫度就不要太低。如果變頻空調工作時的功率一直保持不高于400w，那么5度電可以讓空調運行12個小時，如果空調滿負荷運行，才能工作5個小時。因此建議可以再增大太陽能電池板的數量(liang)，少要(yao)增(zeng)加到6塊(kuai)或者(zhe)8塊(kuai)。因為(wei)上(shang)邊全是理(li)論計算，實際上(shang)存在轉(zhuan)換(huan)率的問題(ti)，而且如果太(tai)陽照射的時(shi)候(hou)熱，太(tai)陽能(neng)發的電(dian)剛好被空(kong)調(diao)(diao)用完，等太(tai)陽光(guang)照不(bu)強時(shi)，空(kong)調(diao)(diao)就不(bu)能(neng)運轉(zhuan)了，此時(shi)蓄電(dian)池電(dian)量(liang)幾乎為(wei)0。
