Solar panels are photoelectric semiconductor sheets that use sunlight to directly generate electricity, which play a huge role in various fields of new energy, it is widely used, as long as it is photovoltaic products will be used to it. The quality of solar panel components is directly related to the energy efficiency of the products used. Today, there are many manufacturers producing solar panels, and some inferior products are also mixed in, and it is not easy to choose good quality solar panels, the following Xinnuo New Energy will tell you how to distinguish the quality of solar panels.

1, look at the front first to carefully look at the surface of the tempered glass, which is also some solar panel manufacturers careless place. If the surface of the tempered glass accidentally drops silicone, it should be cleaned in time, if it is not clear, it will affect the power generation efficiency of the panel.

2, look at the battery many irregular manufacturers in order to save costs, but ran with damaged batteries to assemble, composed of seemingly more complete battery, in fact, there is a great risk, the initial may not see the problem, but the splined battery is easy to cause fracture under long-term use, thus affecting the use of the entire panel, When the temperature is too high, there will be a fire phenomenon, threatening the life of pedestrians.

3, look at the back of the solar panel should be marked with technical parameters, such as: open circuit voltage, short circuit current, working voltage, etc., secondly, to look at the pressure effect of the back of the solar panel, if there are bubbles, folds and other traces after the pressure, then this solar panel is listed as unqualified.

4, the junction box is a connector of the solar cell module, the main role of the solar photovoltaic junction box is to export the electricity produced by the solar cell module through the cable. Whether the junction box is firm is also related to the efficiency of the solar panel, the junction box cover should be firmly and tightly attached to the junction box, and the outlet wire lock head should be rotated freely and tightened. When purchasing solar panels, we must pay attention to the above four points, in addition, we must choose according to the configuration we need, so that the quality of the selected solar panels is more guaranteed and more assured.
