Install the matters needing attention of distributed photovoltaic system is what?

Photovoltaic modules of electrical installation should refer to the corresponding laws and regulations, including electrical relevant laws and regulations and power connection requirements. Please contact the local electricity sector specific terms. Please don't in the absence of security protection measures on the roof installation of photovoltaic modules, the

photovoltaic modules of electrical installation should refer to the relevant provisions, including electric regulation and power supply connection requirements. Please contact the local electricity sector specific terms. Please don't in photovoltaic modules installed on the roof without safety protection measures, including protection against falling, ladders and stairs, personal protective equipment, etc. At the same time, not to install or run in the adverse environment of distributed photovoltaic power generation systems, such as strong winds and wind weather, moisture and frost of the surface of the roof, etc. Photovoltaic power generation system under the condition of light will produce direct current (dc), and current will increase with the increase of light. If touch module of electronic circuit has a risk of electric shock or burns, 30 volts or higher dc voltage may even be fatal. Therefore, in the process of installation and maintenance, in order to cut off the power of the photovoltaic power generation systems, can move them to completely flat environment, or use of opaque material covering the surface of the module. If your operating system in the sun, please use insulated tools, don't wear metal accessories. In order to avoid the arc and the risk of electric shock, do not work in loading cases, disconnect the electrical connections. The plug must be kept dry and clean, to ensure that they are in good working condition. Please do not insert the plug or other metal objects in any other way for electrical connection. Don't use the border around the broken glass, drop and damaged back touch or pv module operation, unless the component is power off and you wear the personal protective equipment. Do not touch the wet parts. Photovoltaic module must be installed in appropriate building or other suitable place ( Such as floor, roof, building facade, etc. ) 。 ) ； Generally it is recommended that the installation of the pv modules Angle should be in more than 10 degrees, so that when it rains have self-cleaning effect. When one or more pv modules are partly or completely shielding performance of the system will be significantly reduced. In general, it is suggested that the component is installed on the year without a shadow of place, to increase the output of photovoltaic (pv) system. Frequent lightning activity of photovoltaic system lightning protection device must be installed. Use note 1. Pv modules for a long time after the operation, dust or dirt will deposit on the surface of the module, reduce the module power output. Usually, it is recommended that the regular cleaning components, to ensure its high power output. This is a less rainfall, at ordinary times should pay more attention to the cleanness of parts. 2. In order to reduce potential shock or thermal shock, generally recommend that in the morning or late afternoon cleaning parts, because the solar irradiance weak parts temperature is low. Especially in the place where the temperature is higher, should pay more attention to. 3. Common front of photovoltaic modules can absorb 5400 mpa snow load. When clearing snow on the surface of the pv modules, please use the brush gently remove snow. Clear ice on the surface of the pv modules can't. Can't clean broken glass photovoltaic modules or exposed cable to avoid the risk. Usually, it is recommended to use a soft brush and strength less than 690000 mpa clean soft water clean glass surface photovoltaic modules, which accord with the standard of municipal cleaning systems.
