隨著光伏的發(fā)展，其中工商業(yè)光伏發(fā)電項目，因為投資，同時還能緩解企業(yè)的產(chǎn)能壓力而備受企業(yè)的青睞，因為光伏發(fā)電和負荷用電相對同步，自發(fā)自用比例很高，在工商業(yè)電價相對較高的情況下，能取得不錯的經(jīng)濟效益。下面來講講工商業(yè)工廠安裝光伏注意的幾個事項。

With the development of photovoltaic technology, industrial and commercial photovoltaic power generation projects are favored by enterprises because of their high investment income and the ability to relieve the pressure of enterprises' production capacity. Because photovoltaic power generation and load power consumption are relatively synchronous, the proportion of spontaneous self-use is high, and good economic benefits can be achieved under the relatively high industrial and commercial electricity prices. Here are some points for attention when installing PV in industrial and commercial plants.

一、屋頂承受能力

1、 Roof bearing capacity

在安裝工商業(yè)光伏電站的時候需要注意，要確認屋頂?shù)某休d能達到安裝光伏電站的要求，要拿到廠房建筑結(jié)構(gòu)圖紙，由結(jié)構(gòu)工程師進線屋面增加荷載計算；如果是彩鋼瓦屋面，要確認彩鋼瓦瓦型，彩鋼瓦屋面破損、腐蝕生銹、防水情況；屋面設(shè)備情況，是否有風(fēng)機、氣窗、采光帶、空調(diào)，是否有女兒墻，女兒墻高度，以現(xiàn)場實際測量為準(zhǔn)。

When installing industrial and commercial photovoltaic power stations, attention should be paid to the confirmation that the bearing capacity of the roof can meet the requirements of installing photovoltaic power stations, and the structural drawings of the plant building should be obtained, and the structural engineer should enter the roof to add the load calculation; If it is a color steel tile roof, confirm the color steel tile type, the color steel tile roof damage, corrosion, rust and waterproof; The situation of roof equipment, whether there are fans, air windows, lighting belts, air conditioners, whether there are parapets, and the height of parapets, shall be subject to the actual measurement on site.

在北方，要注意冬天下雪對支架承載的影響，如果支架設(shè)計載荷末考慮積雪負荷，當(dāng)遭遇大暴雪時，有造成支架全部或局部坍塌的危險，從而導(dǎo)致太陽能電池組件損壞，進而有可能導(dǎo)致整個光伏發(fā)電系統(tǒng)的癱瘓。在沿海地區(qū)，要嚴格參照沿海建筑物的抗風(fēng)抗震參數(shù)進行設(shè)計，選擇具有較強耐壓能力的鍍鋅支架，光伏系統(tǒng)的陣列布置要充分考慮抗風(fēng)的御風(fēng)口。

In the north, we should pay attention to the impact of snow in winter on the bearing capacity of the support. If the design load of the support does not consider the snow load, there is a risk that the support will collapse completely or partially in case of heavy snow, which will lead to the damage of the solar cell module, which may lead to the paralysis of the entire photovoltaic power generation system. In coastal areas, the design shall be carried out in strict accordance with the wind and seismic resistance parameters of coastal buildings, and the galvanized support with strong pressure resistance shall be selected. The array layout of photovoltaic system shall fully consider the wind-resistant wind vent.

當(dāng)然，隨著技術(shù)的發(fā)展，新型的柔性板也可以實現(xiàn)在低荷載前提下，實現(xiàn)輕薄化的光伏發(fā)電。柔性板無邊框，無玻璃，可以彎曲，重量只有常規(guī)的十分之一，3KG。直接膠粘，對荷載老舊廠房有很好的效果。

Of course, with the development of technology, new flexible panels can also realize lightweight photovoltaic power generation under the premise of low load. The flexible plate has no frame, no glass, and can be bent. Its weight is only one tenth of the conventional one, 3KG. Direct gluing has a good effect on the load of old plants.

二、設(shè)備情況

2、 Equipment

除了屋頂承載能力和陰影遮擋之外，工業(yè)廠房還是考察廠房內(nèi)的設(shè)備情況，如果廠家內(nèi)有大型吊車，電焊機，電爐等大功率感性設(shè)備，會造成工業(yè)廠房的電壓不穩(wěn)定，電流諧波超標(biāo)，逆變器的并網(wǎng)點如果接在380V的低壓側(cè)，逆變器會重復(fù)啟動。

In addition to the roof bearing capacity and shadow shielding, the industrial plant still inspects the equipment in the plant. If there are large cranes, welding machines, electric furnaces and other high-power inductive equipment in the factory, the voltage of the industrial plant will be unstable, and the current harmonics will exceed the standard. If the connection point of the inverter is connected to the low voltage side of 380V, the inverter will start repeatedly.

光伏發(fā)電系統(tǒng)的使用與維護的好壞直接影響著系統(tǒng)的使用壽命，影響著系統(tǒng)的運行成本和發(fā)電效率。一般情況下，無需對太陽能電池組件進行表面清潔處理，但對暴露在外的接線接點要進行定期檢查、維護。遇有大風(fēng)、暴雨、冰雹、大雪等情況，應(yīng)采取措施保護太陽能方陣，以免損壞。更多相關(guān)事項就來我們網(wǎng)站http://www.51dwgw.cn咨詢！

The use and maintenance of photovoltaic power generation system directly affects the service life of the system, and affects the operation cost and power generation efficiency of the system. Generally, there is no need to clean the surface of the solar cell module, but the exposed connection points should be regularly inspected and maintained. In case of strong wind, rainstorm, hail, heavy snow, etc., measures shall be taken to protect the solar array to avoid damage.
