隨著光伏的發(fā)展，其中工商業(yè)光伏發(fā)電項(xiàng)目，因?yàn)橥顿Y，同時(shí)還能緩解企業(yè)的產(chǎn)能壓力而備受企業(yè)的青睞。下面來(lái)講講工商業(yè)光伏發(fā)電安裝要注意三大點(diǎn)具體什么內(nèi)容。

With the development of photovoltaic, industrial and commercial photovoltaic power generation projects are favored by enterprises because of their high return on investment and the ability to relieve the pressure on enterprises. Now let's talk about what the three major points of industrial and commercial photovoltaic power generation installation should pay attention to.

1.屋頂承受能力

1. Roof bearing capacity

而在安裝工商業(yè)光伏發(fā)電電站的時(shí)候需要注意，要確認(rèn)屋頂?shù)某休d能達(dá)到安裝光伏電站的要求，要拿到廠(chǎng)房建筑結(jié)構(gòu)圖紙，由結(jié)構(gòu)工程師進(jìn)線(xiàn)屋面增加荷載計(jì)算；如果是彩鋼瓦屋面，要確認(rèn)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(jī)、氣窗、采光帶、空調(diào)，是否有女兒墻，女兒墻高度，以現(xiàn)場(chǎng)實(shí)際測(cè)量為準(zhǔn)。

During the installation of industrial and commercial photovoltaic power plants, attention should be paid to confirming that the roof bearing capacity can meet the requirements for the installation of photovoltaic power plants. The building structure drawings of the plant should be obtained, and the structural engineer should increase the load on the incoming roof; If it is color steel tile roof, confirm the color steel tile type, damage, corrosion, rust and waterproof of color steel tile roof; Roof equipment, whether there are fans, air windows, lighting belts, air conditioners, whether there are parapets, and the parapet height shall be subject to the actual measurement on site.

在北方，要注意冬天下雪對(duì)支架承載的影響，如果支架設(shè)計(jì)載荷末考慮積雪負(fù)荷，當(dāng)遭遇大暴雪時(shí)，有造成支架全部或局部坍塌的危險(xiǎn)，從而導(dǎo)致太陽(yáng)能電池組件損壞，進(jìn)而有可能導(dǎo)致整個(gè)光伏發(fā)電系統(tǒng)的癱瘓。在沿海地區(qū)，要嚴(yán)格參照沿海建筑物的抗風(fēng)抗震參數(shù)進(jìn)行設(shè)計(jì)，選擇具有較強(qiáng)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, 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, when encountering heavy snow, there is a danger that the support will collapse completely or partially, resulting in damage to the solar cell modules, which may lead to the paralysis of the entire photovoltaic power generation system. In coastal areas, the design shall strictly refer to the wind resistance and earthquake 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 air outlet.

2.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(chǎng)房還是考察廠(chǎng)房?jī)?nèi)的設(shè)備情況，如果廠(chǎng)家內(nèi)有大型吊車(chē)，電焊機(jī)，電爐等大功率感性設(shè)備，會(huì)造成工業(yè)廠(chǎng)房的電壓不穩(wěn)定，電流諧波超標(biāo)，逆變器的并網(wǎng)點(diǎn)如果接在380V的低壓側(cè)，逆變器會(huì)重復(fù)啟動(dòng)，如果電壓變化過(guò)快，甚至還有可能造成逆變器炸機(jī)。

In addition to the roof bearing capacity and shadow shielding, the equipment in the industrial plant is also inspected. If there are large cranes, electric welding machines, electric furnaces and other high-power inductive equipment in the factory, the voltage in the industrial plant will be unstable, and the current harmonics will exceed the standard. If the inverter's grid point is connected to the low-voltage side of 380V, the inverter will start repeatedly. If the voltage changes too fast, it may even cause the inverter to explode.

3.定期檢查和清理

3. Regular inspection and cleaning

光伏發(fā)電系統(tǒng)的使用與維護(hù)的好壞直接影響著系統(tǒng)的使用壽命，影響著系統(tǒng)的運(yùn)行成本和發(fā)電效率。一般情況下，無(wú)需對(duì)太陽(yáng)能電池組件進(jìn)行表面清潔處理，但對(duì)暴露在外的接線(xiàn)接點(diǎn)要進(jìn)行定期檢查、維護(hù)。遇有大風(fēng)、暴雨、冰雹、大雪等情況，應(yīng)采取措施保護(hù)太陽(yáng)能方陣，以免損壞。

The use and maintenance of photovoltaic power generation system directly affects the service life of the system, the operation cost and power generation efficiency of the system. Generally, it is not necessary 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 from damage.

此外光伏發(fā)電和負(fù)荷用電相對(duì)同步，自發(fā)自用比例很高，在工商業(yè)電價(jià)相對(duì)較高的情況下，能取得不錯(cuò)的經(jīng)濟(jì)效益。所以您對(duì)此方面有什么需求或者興趣的話(huà)，歡迎來(lái)聯(lián)系我們http://www.51dwgw.cn！

In addition, photovoltaic power generation and load power consumption are relatively synchronous, and the proportion of spontaneous self use is very high. In the case of relatively high industrial and commercial electricity prices, good economic benefits can be achieved.
