From distributed solar photovoltaic power generation system is becoming more and more families to ground mass concentration plant, began in 2010 across the country are built, the quality problem of the power plant is also a matter of concern to many owners, learning from the surrounding friends, photovoltaic building

a growing number of solar photovoltaic power generation system is under construction. From home to the large centralized power stations on the ground, since 2010, they have built all over the country. The quality problem of the power station has become a matter of concern to many of the owners. From friends, after completion of photovoltaic power generation, happiness is to enjoy the benefits of environmental protection, and trouble is generating capacity is not high, there is always a problem! Power station is an important part of a front end solar modules, also known as photovoltaic panels, the 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? From the businessman's point of view, it is very important to choose formal manufacturers. Some of the industry is very famous, has a good reputation, it is the premise. If can be a large number of procurement, on-site inspection of the factory so the quality can be guaranteed. Second, look at the manufacturing process, it is relatively straightforward, see if there are any leaks, the cell is welded together. I believe that even the layman can directly from appearance. Three see the quality of back pressure, the pressure is not uniform, or air bubbles, wrinkles, and so on. Bubbles and fold need careful observation, not easy to see in the sun. Four to see the quality of the border, whether strict rectangle, the error is too big. Five conversion rate, high conversion rate is the guarantee of a stable income!
