1. Look at the surface

仔細查看鋼化玻璃表面，一般小廠家為了提高生產速度，往往不在意無意間滴落在鋼化玻璃表面的硅膠。不清除的話會降低電池板的發(fā)電效率。

Careful inspection of the surface of tempered glass shows that small manufacturers often do not pay attention to the unintentional dripping of silicone on the surface of tempered glass in order to improve production speed. If not cleared, it will reduce the power generation efficiency of the battery panel.

2、看電池片

2. Look at the battery pack

很多不正規(guī)的廠家用破碎的電池片拼接，組成看似完整的電池片進行焊接，這種方式存在很大風險，初期可能不是很明顯，但是拼接的電池片后期容易再次斷開，影響整塊電池板的使用。

Many unscrupulous manufacturers use broken battery cells to splice together and form seemingly complete battery cells for welding. This method carries great risks, which may not be obvious in the initial stage, but the spliced battery cells are easily disconnected again in the later stage, affecting the use of the entire battery panel.

3、看背面

3. Look at the back

看背面承壓的質量，承壓后有沒有不平整的情況出現，如氣泡、褶皺之類的。

Check the quality of the pressure on the back and see if there are any unevenness, such as bubbles, wrinkles, etc. after the pressure is applied.

4、看邊框

4. Look at the border

由于太陽能電池板行業(yè)進入門檻低，很多小廠家采用人工打框的方式，人工打框由于每次打框的力度不均，打好的框接觸緊密程度也不一，造型不成嚴格的矩形，牢固程度也大打折扣。

Due to the low entry threshold of the solar panel industry, many small manufacturers use manual framing. Due to the uneven force of each framing process, the tightness of the finished frames varies, and the shape is not strictly rectangular, resulting in a greatly reduced degree of firmness.

5、看硅膠

5. Look at silicone

看背面四周硅膠是否均勻分布，是否緊密滲入背板和邊框的縫隙。

Check if the silicone around the back is evenly distributed and tightly penetrates into the gaps between the back panel and frame.

6、看焊接

6. Look at welding

仔細觀察電池片的串焊有無漏焊現象。同時也要看下電池片排列是否規(guī)整。

Carefully observe the string welding of the battery cells for any solder leakage. At the same time, it is also necessary to check whether the battery cells are arranged neatly.

7、看接線盒

7. Check the junction box

后看接線盒是否牢固，接線盒蓋子是否能牢靠、緊密地貼在接線盒上;看出線電線鎖頭是否旋轉自如，能否收緊。

Check whether the junction box is secure and whether the cover of the junction box can be firmly and tightly attached to the junction box; Check if the wire lock can rotate freely and tighten.
