安裝光伏電站以后，難免會遇到這樣的情況：灰塵、落葉、鳥糞等堆積在組件表面，十分影響光伏電站的發(fā)電量，所以定期清洗光伏電站太陽能板就很有必要。根據(jù)業(yè)內人士統(tǒng)計， 經(jīng)常清洗光伏太陽能板，每年能夠有效提升約8%的發(fā)電量呢。

那么，光伏太陽能板怎么清洗呢?多久清洗一次比較合適?用什么工具清洗光伏板最好呢?今天，我們?yōu)槟阋灰唤獯稹?/span>

清洗時，如果太陽能板表面只有少量灰塵的情況下，只需用高壓水槍進行簡單沖洗即可。

如果表面有沙子、泥塊等顆粒狀污染物，可以先用高壓水槍沖洗，將顆粒物沖走，再用軟毛刷進行刷洗，避免顆粒物粘在電板上。

如果表面有鳥糞等黏稠污染物以及油性污染物時，需用干凈的抹布來擦除，并配合玻璃水進行清洗，最后用水槍沖洗。

需要注意的是，在使用高壓水槍的過程中，要注意高壓水槍的壓力，水壓過大可能對太陽能電池板產(chǎn)生損傷。

清洗太陽能板的時候需要注意哪些事項呢？

(1) 清洗時間最好選擇在清晨、傍晚或者夜間，避開中午等高溫時段清洗，以免對太陽能電池板造成損傷。

(2) 清洗時要注意避免使用硬物、尖銳物品直接接觸太陽能板。

(3) 不能踩踏太陽能板、支架及其他零部件，容易損壞電站，影響使用壽命。

根據(jù)目前的行業(yè)運維經(jīng)驗來看，冬季等雨雪較多的季節(jié)，一般每月清洗一次即可 （如果有積雪現(xiàn)象，要及時清理），其余月份每月清洗兩次即可 。西北等風大、多灰的地區(qū)，就需要視具體情況來定了。

需要注意的是：組件清洗時盡量不要用肥皂水 ，平時我們用肥皂洗手時，手上會留有一層薄薄的膜，同樣的道理，用肥皂清洗組件后，也會在光伏組件表面留下一層薄膜或殘留物，會促使灰塵等更快地附著和堆積，影響電站發(fā)電量。除此之外，也不易使用其他腐蝕性清洗劑。

After installing a photovoltaic power station, it is inevitable to encounter situations where dust, fallen leaves, bird droppings, and other debris accumulate on the surface of the modules, greatly affecting the power generation of the photovoltaic power station. Therefore, it is necessary to regularly clean the solar panels of the photovoltaic power station. According to industry insiders, regularly cleaning photovoltaic solar panels can effectively increase power generation by about 8% annually.

So, how to clean photovoltaic solar panels? How often is it appropriate to clean it? What is the best tool to clean photovoltaic panels with? Today, we will answer you one by one.

Cleaning tools for solar panels are also quite common, commonly used include high-pressure water guns, soft bristled brushes, cotton mops, etc. These tools have low costs and are also very convenient to use.

When cleaning, if there is only a small amount of dust on the surface of the solar panel, simply rinse it with a high-pressure water gun.

If there are granular pollutants such as sand and mud on the surface, you can first rinse with a high-pressure water gun to remove the particles, and then brush with a soft bristled brush to avoid the particles sticking to the electrical board.

If there are sticky pollutants such as bird droppings and oily pollutants on the surface, it is necessary to use a clean cloth to wipe them off and clean them with glass water. Finally, rinse with a water gun.

It should be noted that during the use of high-pressure water guns, attention should be paid to the pressure of the high-pressure water gun. Excessive water pressure may cause damage to the solar panel.

What precautions should be taken when cleaning solar panels?

(1) It is best to choose the cleaning time in the morning, evening, or night, avoiding high-temperature periods such as noon to avoid damage to the solar panels.

(2) When cleaning, be careful not to use hard or sharp objects that directly come into contact with the solar panel.

(3) Do not step on solar panels, brackets, and other components as they can easily damage the power station and affect its service life.

Based on current industry operation and maintenance experience, in winter and other rainy and snowy seasons, it is generally sufficient to clean once a month (if there is snow accumulation, it should be cleaned in a timely manner), and in other months, it is sufficient to clean twice a month. In areas with strong winds and a lot of gray in the northwest, it depends on the specific situation.

It should be noted that when cleaning modules, try not to use soapy water. Usually, when we wash our hands with soap, there will be a thin film on our hands. Similarly, after cleaning modules with soap, a thin film or residue will also be left on the surface of photovoltaic modules, which will promote faster adhesion and accumulation of dust and other substances, affecting the power generation of the power plant. In addition, it is also not easy to use other corrosive cleaning agents.
