Handan Yingli photovoltaic power generation equipment integrity and mutual benefit

if you don't know Handan Yingli photovoltaic power generation equipment integrity and mutual benefit, then don't worry now, I will introduce Handan Yingli photovoltaic power generation equipment integrity and mutual benefit to you! 3) The installation position of the controller should be well ventilated, and the finishing of the intermediate and downstream products of hexanoic acid should be focused on to prevent the temperature of the heat dissipation parts from being too high. The shell of the controller should be reliably grounded. 4) Before wiring, confirm the identification symbols of solar cell module, wind turbine generator, battery and load on the controller, and connect

if the system efficiency index of the power station is not within the reasonable range, it is necessary to further analyze the energy loss of the whole photovoltaic power generation system of the power station and find out the abnormal points of energy loss. Generally, it is recommended to use soft brush and clean and mild water when cleaning the glass surface of photovoltaic modules. The force used should be less than 690kpa, which meets the standard of municipal cleaning system· Power station energy consumption analysis Handan photovoltaic power generation equipment integrity and mutual benefit after the solar radiation energy flows through photovoltaic modules, combiner boxes, inverters, box transformers, main transformers and other equipment, there will be varying degrees of energy loss, and its energy loss can be measured by photovoltaic array absorption loss, inverter loss, collector line and box transformer loss how to correctly clean the barrel and booster station loss, Combined with the analysis results of the operation data of a 10.16gw power station, it is concluded that the reasonable loss range of each section is as follows: 1) the loss of the collector line and box transformer and the loss of the booster station are usually closely related to the performance of the equipment itself, and the power loss is relatively stable. Generally, the loss of the collector line and box transformer is about 1.5%, and the loss of the booster station is about 0.6%

unless the electrical connection of the module is disconnected and you wear personal protective equipment, do not touch or operate the photovoltaic module with broken glass, falling frame and damaged backplane. Do not touch wet components. PV modules must be installed in suitable buildings or other places suitable for module installation (such as ground, roof, house side elevation, etc.); Generally, it is recommended to install photovoltaic modules with an inclination angle of more than 10 degrees, so as to play a self-cleaning role in case of rain; When one or more photovoltaic modules are partially or completely blocked, the system performance will be significantly reduced

Handan Yingli photovoltaic power generation equipment integrity and mutual benefit production process module production process through cell sorting - single welding - string welding - splicing (that is, the series welded cells are spliced together) - intermediate test (intermediate test points: infrared test and appearance inspection) - lamination - trimming - appearance after layer - infrared after layer - such as high-purity graphite paper. Only large phosphorous graphite can be used as the raw material frame (generally aluminum frame) - junction box installation - Cleaning - Test (this link is also divided into "infrared" line test and visual inspection to determine the level of the component) - packaging (1) Due to the randomness of the manufacturing conditions of the battery, the battery performance produced by the battery test is different, so in order to effectively combine the batteries with the same or similar performance, it should be classified according to their performance parameters; Battery test is to classify the battery by testing its output parameters (current and voltage). The whole is called module, that is, photovoltaic module or solar cell module. And they are packaged on a stainless steel, aluminum or other non-metallic frame, installed with the upper glass and the back plate, filled with nitrogen and sealed

the above is Handan Yingli photovoltaic power generation equipment sorted out for you. It is honest and mutually beneficial for your reference
