How to install solar photovoltaic panels?

Solar street lamps mainly through the panel light, so as to realize the back of the photoelectric conversion, and let the light shine, if the panel is not installed well, probably won't want the lighting effect. This installation not only refers to a set of

mainly through panels to receive light, solar street lamps on the back of the photoelectric conversion, successful lighting light source. If panels installed improperly, probably can't achieve the desired lighting effect. This not only refers to the parts of installation is loose, or whether the above obstacles, etc. , including its installation Angle, some of the above safety device, etc. Must not be careless. So, what problem should be paid attention to when installing solar street light? First, select the frame material solar usually by a steel framework. In fact, some properties of this kind of material is not very good. In order to ensure the use effect of them, they usually be galvanized in order to improve their corrosion resistance. However, some manufacturers use solar street lamps cold galvanizing to save costs. Treated with this method of coating is very thin and poor corrosion resistance. Should pay attention to distinguish. If it is in the coastal cities like yichang, where heavy salt fog, best choice through overheating processing of stainless steel or aluminum alloy. They have higher corrosion resistance, durability is higher. If it is in this environment is suitable for yichang city, the choice of the panel frame can be according to their actual needs. In addition, in addition to choose a good framework material, must also ensure that the framework and basic welding or installation is firm, and solar panels can have enough strength and stability to resist the weather such as wind or snow. Install solar panels, after all, no obstacles. Second, find out the components of the positive and negative second, when installation, panels are negative should be clear, should not have polarity. If the wrong polarity, panels will not be able to work, charging will not full, the light on the controller will not be able to light up, it can even burn out diode. Therefore, must pay attention. In addition, the conductor should be as short as possible, reduce the internal resistance of the circuit, the connection is firm, increased contact resistance, so the efficiency will be higher. In addition, still should pay attention to the environment temperature. According to the temperature, the temperature of the conductor parameters when installation should have allowance. Three, the installation of lightning protection device installing panels, should also pay attention to install lightning protection devices, especially suitable for thunderstorm more cities. Otherwise, a nearby lightning is easy to cause overvoltage and overcurrent, the battery will be damaged by lightning shock on the back. In general, special photovoltaic power SPD is installed on the DC power distribution cabinet ( Mother's head) , the panels can be appropriately equipotential grounding and prevent direct lightning stroke. South to solar street light in this respect is quite skilled. Four, not to install the photovoltaic power station panel with metal jewelry, had better not wear metal accessories, in order to prevent the panel is negative direct contact with metal objects. Otherwise, the short circuit may occur, serious when even fires and explosions.
