Solar panels, also known as solar chips, are optoelectronic semiconductor chips directly generated by sunlight. It plays a huge role in various fields of new energy and has been widely applied. Next, the editor of Fantasy Solar will briefly introduce how to identify the quality of solar panels, hoping to be helpful to everyone.
1. Look at the front
It is necessary to carefully observe the surface of tempered glass, which is something that some solar panel manufacturers do not pay attention to. The surface stains should be cleaned in a timely manner, otherwise it will affect the efficiency of the battery. Solar panels
2. Check the battery
In order to save costs, many unscrupulous manufacturers even assemble damaged solar cells into seemingly complete ones. In fact, there are significant risks involved. Problems that may not be visible in the early stages, but can easily break down after prolonged use. It affects the entire solar panel, and when the temperature is too high, a fire phenomenon will occur, posing a threat to people’s safety.
3. Look at the back
The design of the back of the solar panel should indicate safety technical parameters, such as open circuit output voltage, short circuit fault current, working voltage, etc., which depend on the pressure bearing effect control panel on the back of the solar panel. If a large number of bubbles or wrinkles appear after pressurization, the developed solar panel is classified as unqualified. Battery board
4. Check the junction box
A junction box is a type of connector for solar cell modules, whose main function is to output the electrical energy generated by the solar cell module manufactured by the cable through the cable. The firmness of the junction box also affects the efficiency of the solar panel. The junction box cover and junction box are firmly attached, and the outlet lock should rotate freely and tighten.
When purchasing solar panels, it is important to pay attention to the above four points. In addition, we must be able to choose according to the configuration we need.
