How to buy solar panels?
Solar panels are photovoltaic semiconductor wafers that use sunlight to generate electricity directly. They play a huge role in various fields of new energy. They are widely used, as long as they are photovoltaic products. The quality of solar panel components will directly affect the energy efficiency of the products used. Nowadays, there are many manufacturers producing solar panels, and some inferior products are also mixed in. It is not easy to select high-quality solar panels. Next, Xinnuo New Energy will tell you how to judge the quality of solar panels.
1. Look at the front
First of all, carefully check the surface of tempered glass, which is also the carelessness of some solar panel manufacturers. If silica gel drops on the surface of tempered glass accidentally, it should be removed in time. If it is not removed, it will affect the power generation efficiency of the battery panel.
2. Look at the battery
In order to save costs, many irregular manufacturers try to assemble damaged battery pieces to form seemingly complete battery pieces. In fact, there are great risks. There may be no problems at the initial stage, but the spliced battery pieces are easy to break under long-term use, thus affecting the use of the entire battery panel. When the temperature is too high, there will be fire, threatening the life safety of pedestrians.
3. Look at the back
The back of the solar panel should be marked with technical parameters, such as open circuit voltage, short circuit current, working voltage, etc. Secondly, the pressure bearing effect of the back of the solar panel should be considered. If bubbles, wrinkles and other traces appear after pressure bearing, the solar panel will be classified as unqualified.
4. Look at the junction box
The junction box is a connector of the solar cell module. The main function of the solar photovoltaic junction box is to export the electrical energy produced by the solar cell module through the cable. Whether the junction box is firm also affects the working efficiency of the solar panel. The junction box cover should be firmly and tightly attached to the junction box, and the outlet wire lock should rotate freely and tighten.
When purchasing solar panels, y must pay attention to the above four points. In addition, you should choose according to the configuration you need. In this way, the quality of the selected solar panels is more guaranteed, safe and secure. are photovoltaic semiconductor wafers that use sunlight to generate electricity directly.
