相信大家對太陽能系列中的蘭州太陽能路燈都很熟悉，這是新農村道路照明所必需的。目前，太陽能路燈在中國農村的普及率已經達到50%以上，預計到2020年將在農村全面普及。然而，許多地區選擇的太陽能的路燈配置并不合理。經常發生的情況是，照明時間短，雨天的持續時間短。那么我們應該如何計算高桿路燈的配置呢?接下來，我們就來教大家如何計算蘭州太陽能路燈。

1、假設我(wo)們(men)的照(zhao)(zhao)明(ming)(ming)(ming)時(shi)間為(wei)(wei)(wei)6小時(shi)，前3小時(shi)為(wei)(wei)(wei)全(quan)(quan)功(gong)(gong)(gong)率(lv)(lv)(lv)照(zhao)(zhao)明(ming)(ming)(ming)，后3小時(shi)為(wei)(wei)(wei)半功(gong)(gong)(gong)率(lv)(lv)(lv)照(zhao)(zhao)明(ming)(ming)(ming)，則每日全(quan)(quan)功(gong)(gong)(gong)率(lv)(lv)(lv)照(zhao)(zhao)明(ming)(ming)(ming)時(shi)間為(wei)(wei)(wei)3+3·0.5=4.5小時(shi)。如果持(chi)續(xu)4天下雨天，因為(wei)(wei)(wei)太(tai)陽能板也可以(yi)在下雨天充電，我(wo)們(men)可以(yi)將下雨天設置為(wei)(wei)(wei)3天。2、各地區日照(zhao)(zhao)系數和日照(zhao)(zhao)高(gao)峰(feng)時(shi)數不(bu)同(tong)。3、LED燈(deng)(deng)6米(mi)的功(gong)(gong)(gong)率(lv)(lv)(lv)一(yi)般(ban)為(wei)(wei)(wei)30w或(huo)40w, 7米(mi)的功(gong)(gong)(gong)率(lv)(lv)(lv)一(yi)般(ban)為(wei)(wei)(wei)40w或(huo)50w, 8米(mi)的功(gong)(gong)(gong)率(lv)(lv)(lv)一(yi)般(ban)為(wei)(wei)(wei)50w或(huo)60w。我(wo)們(men)可以(yi)為(wei)(wei)(wei)高(gao)桿(gan)路燈(deng)(deng)廠家(jia)提(ti)供(gong)路燈(deng)(deng)桿(gan)的高(gao)度，合(he)理匹配(pei)LED燈(deng)(deng)的比(bi)功(gong)(gong)(gong)率(lv)(lv)(lv)。

如何計算蘭州高桿路燈的配置

例如(ru)，蘭州太(tai)陽(yang)(yang)能(neng)(neng)(neng)路燈(deng)(deng)需要安裝在一個30W LED電(dian)(dian)(dian)源(yuan)的(de)(de)地(di)方。燈(deng)(deng)將每(mei)天以較(jiao)(jiao)大(da)功率(lv)亮4.5小時。下雨(yu)天持續4天。太(tai)陽(yang)(yang)能(neng)(neng)(neng)的(de)(de)路燈(deng)(deng)系統(tong)電(dian)(dian)(dian)壓為(wei)(wei)12V。首先(xian)，我(wo)(wo)們(men)可(ke)以計算(suan)出太(tai)陽(yang)(yang)能(neng)(neng)(neng)的(de)(de)路燈(deng)(deng)每(mei)晚的(de)(de)耗(hao)電(dian)(dian)(dian)量(liang)為(wei)(wei)30W·4.5H=135WH, 4個雨(yu)天所需電(dian)(dian)(dian)量(liang)為(wei)(wei)135WH·4=540WH。如(ru)果(guo)電(dian)(dian)(dian)量(liang)用完(wan)，需要在2天內(nei)充滿電(dian)(dian)(dian)，則太(tai)陽(yang)(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池板的(de)(de)功率(lv)為(wei)(wei)540WH/8H ÷ 0.85≈60Wp, 0.85為(wei)(wei)太(tai)陽(yang)(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池板的(de)(de)充電(dian)(dian)(dian)效率(lv)。由于(yu)太(tai)陽(yang)(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池板會造成(cheng)衰減，并且(qie)會受(shou)到當地(di)環(huan)境粉塵的(de)(de)影響，我(wo)(wo)們(men)較(jiao)(jiao)好將太(tai)陽(yang)(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池板的(de)(de)功率(lv)提高到70Wp。
