To determine the method of solar panels is good or bad

Solar panels are easily trampled and impacted during transportation, handling and installation, resulting in imperceptible hidden dangers of the components and greatly affecting the use of components. So how to judge the solar panel is good or bad? Solar panels are made of tempered glass, solar cells in series, EVA, TPT, aluminum shell, junction box composition, we in the inspection and acceptance, but also need to start from these parts.

1, look toughened glass surface. In order to increase the production speed, small manufacturers often inadvertently drop the silica gel on the tempered glass surface. Silica gel on the surface will reduce the power generation efficiency of the solar panel.

2, see the solar cell welding. Some small manufacturers to save costs, the use of broken cell welded together, there is a big risk of such battery components, if the battery splicing is not good, easy to disconnect again later, affecting the use of the entire panel. Large manufacturers use cell string soldering method, welding firm, arranged regularly.

3, look at the back. See the quality of the back pressure, there is no pressure after the emergence of irregularities, such as bubbles, folds and the like.

4, look at the border. Many small manufacturers use manual boxing mode, because the intensity of artificial boxing is uneven, the boxed box has a tight contact degree, can not become a qualified rectangle, and the firmness is also greatly reduced.

5, look at the silicone. Look around the back of the silica gel is evenly distributed, whether the tight infiltration back and the border of the gap.

6, to see if the junction box junction box lid can be firmly and tightly attached to the junction box; outlet wire lock whether the rotation freely, can tighten.

In summary, we can see that the quality of solar panels to control the point is more, we have to judge from the subtleties of good or bad quality.
