How to distinguish between the advantages and disadvantages of 6 meters high solar street light photovoltaic panels?

Can solar power generation system is becoming more and more is the most important part of the solar cell components, also known as photovoltaic panels, the panels. Its quality directly affects the work efficiency of the system and the service life, how to distinguish between the solar cell

more and more solar power systems are under construction. Is the most important components of the solar cell components, also known as photovoltaic panels and panels. Its quality directly affect the work efficiency and service life of the system. How to distinguish the quality of the solar panels, photovoltaic panels and the battery module? See the color. In general, the appearance of monocrystalline silicon and polycrystalline silicon panel color to blue, light blue or blue relatively uniform. If the color of the panels is dark and not the same, so do manual work is certainly not careful. two Look at the surface. Panels of toughened glass surface should be smooth, no foreign body. In order to improve the production speed, small manufacturer not clean drop in toughened glass on the surface of silica gel. If the silicone is not clean, will affect the power generation efficiency. 三世。 Look at the battery. Panels on each cell is full, and the cutting of the whole. However, many irregular manufacturers on the market will be broken cell joining together into what seems to be a complete cell is used for welding. We took a look and see whether there are traces of cutting. This method has a lot of risk, in the initial stage may not be obvious, but after mosaics of cell in the later is easy to disconnect again, affect the use of panels. Of course, it can be difficult to detect with the naked eye. 第四。 Look back. After check the back pressure on the quality, the pressure to see if there is uneven, such as air bubbles and fold. V。 Look at the border. Due to the solar panel industry with low barriers to entry, many small manufacturers use manual framework. Since each frame strength uneven, points box contact uneven tightness, shape also not strictly for rectangle, so strong degree is reduced greatly. At present, the commonly used aluminum alloy frame. Vi . Look at the silica gel. Look at the back, to see if the silicone is uniformly distributed, whether to close the gaps between the permeate back and framework. Seven. Look at the weld. Careful observation of cell series welding with and without leakage. At the same time also want to see whether the arrangement of cell regularly. Eight. Look at the junction box. Whether can check box, junction box cover firmly firmly fixed on the box. To see whether can rotate freely and tighten the locks. Nine. Look at the price. If all of these are indistinguishable. The safest way is to compare prices. Domestic price fluctuation in the panels, although not, but there will be an approximate range. If a manufacturer price is far lower than the market price, so we should be careful to distinguish them. Manufacturers necessary qualification certificates issued by the corresponding panels, qualification documents, etc.
