The quality of the photovoltaic modules should be how to choose?

Power station is the most important part of the front is solar battery components, also known as photovoltaic panels, the panels. Its quality is directly affects the work efficiency of the system and the service life of the layman how to discern the stand or fall of photovoltaic modules?

plant front end is the most important components of the solar battery components, also known as photovoltaic panels and panels. Its quality will directly affect the work efficiency and service life of the system. Dilettante how to distinguish between good and bad pv modules? One of my friends live in this city since I was a child. She can move back and forth on the road any car pointed out that all kinds of clothing brand and trademark. But when she went to the countryside, she can't tell wheat seedlings and leek, a donkey and a horse. In fact, this is a very normal thing, because the content of the textbook is very abstract, mechanization of memory is often different from reality. Get back to business, solar photovoltaic power generation is not only widely used in the city, also is not rare in rural areas. As more and more farmers to build power plants, the quality of the power station has become a problem concerned by many of the owners. For building photovoltaic power station users in rural areas, they do not know the quality of the equipment, let alone a photovoltaic system of professional and technical knowledge. A friend who is engaged in the photovoltaic industry more than ten years tells us that rural users set up photovoltaic power station, they also happy and worry. They are happy to enjoy the benefits of environmental protection. They worry about low power and continuous power stations. But the farmers are worried. So how to make the pv power plant away from the hidden trouble? What skills are needed for us ordinary people? Today, let's talk about photovoltaic module, it is an important part of photovoltaic power station. Power station front solar cell components, is the most important parts of is also known as photovoltaic panels and panels. Its quality is directly influence the work efficiency and service life of the system. Dilettante how to distinguish the stand or fall of panels? You need to 'five' of the necessary skills. Look at those businessmen. Look at the components suppliers. See if it is not the mainstream brand of the industry, the Ministry of Industry and Information Technology released access enterprise, there are 244 companies in five batches. As the saying goes, 'good under the tree enjoys the cool air, big brand parts quality assurance and after-sales service guarantee. Second, look at the welding process. If there is a leak check the battery slice series welding. This can see from appearance directly. Look at the quality of the back pressure. Whether to have uneven pressure, or air bubbles, wrinkles, and so on. It is not difficult to find bubbles and wrinkles, you can see them in the sun. Look at the quality of the boundary. Regardless of whether it is strict rectangle, error is too big. Fifth, look at the conversion rate. High conversion rate is the guarantee of a stable income! The conversion efficiency is not obvious on the surface, need the component parameter is used in the comparison. In 60 common polycrystalline silicon photovoltaic modules, for example: 250 watts photovoltaic conversion efficiency of 15 components. 4%; 255 watts photovoltaic conversion efficiency of 15 components. 7%. 260 watts photovoltaic modules of conversion efficiency is 16%; 265 watts conversion efficiency of photovoltaic modules as 16. 3%. 270 watts conversion efficiency of photovoltaic modules as 16. 6%; If a company as a brand of polysilicon 60 p photovoltaic panels conversion rate over 20%, ha ha! Must be a fake! ！
