How to identify zhengzhou solar street light

Solar street lamps manufacturer want to choose the good quality of solar panels is hard, lang bright lighting below, just to tell you about how to distinguish the stand or fall of solar street light photovoltaic panels. 1, the front must first take a closer look at the surface of toughened glass, which is some solar

solar street lamp manufacturers choose high quality solar panels is really not easy. Here's how to judge of solar street light photovoltaic panels. 1, look at the front first, toughened glass surface should be checked carefully, which is why some solar photovoltaic panels manufacturer's carelessness. If the silicone accident drop in toughened glass surface, should be timely cleaning, otherwise it will affect the efficiency of the panels. 2. Look at photovoltaic panels in order to save costs, many informal manufacturers use damaged photovoltaic panels to assemble actually looks relatively complete photovoltaic panels. In fact, the risk is very big, the problem may not appear in the initial stage. However, joining together the photovoltaic panels easy to fracture in use for a long time, which affects the use of photovoltaic panels. If the temperature is too high, there will be a fire phenomenon, threatened the life safety of the pedestrians. 3. Solar photovoltaic panels shall be marked on the back look at the technical parameters, such as the open circuit voltage, short circuit current, working voltage, etc. Second, it depends on the solar panels on the back of the confined effect. If the pressure after the bubble, fold, such as signs, solar photovoltaic panels as unqualified. 4. Look at the junction box junction box is a kind of solar cell components connector. The main functions of the solar pv junction box is produced through the cable output solar battery components of electricity. Junction box is whether it is firmly related to the working efficiency of the solar panels. Junction box cover should be firm, firmly connected to the terminal block, wire free rotation and tighten the lock. Buy solar photovoltaic panels, we must pay attention to the above four. In addition, we must be conducted in accordance with the requirements of driveway lights configuration options, so that the quality of the selected solar photovoltaic panels get more security, more and more secure.
