The installation of solar panels component process

by:SRS     2020-11-05
Solar panel component is the sun light energy directly into direct current (dc) can sunshine power systems. Multiple components of series and parallel phalanx of power generation, and provide a larger electric power. Solar cell module has the individual components big power, the characteristics of high reliability, can be used of single or array. Components are made from high conversion efficiency of single solar cell, anti-aging EVA film, high light transmittance and low iron tempered glass and composed of fluorine plastics, polyester composite Tedlar ( TPT) Back of membrane. These components under vacuum heating laminate as a whole, the final anodized anti-corrosion aluminum alloy frame and junction box, become a finished product components. With high efficiency, long life, easy installation, wind resistance, resistance to hail ability etc. Collect a variety of advantages in the integration of solar panels, but for the your production of photovoltaic modules, how about next, explain the photovoltaic solar energy for all components production line process: 1, the battery test: solar street lamps, due to the randomness of the cell production conditions to produce different battery performance, so in order to effectively performance is consistent or similar battery together, so should be classified according to their performance parameters; Battery test by test that the battery output parameters ( Current and voltage) The size of the classification. To improve the utilization rate of the battery and make the quality qualified battery components. 2, positive welding: take bus welded to the battery positive ( Cathode) The main gate line, bus for tin plating copper strip, we use the welding machine welding can be in the form of multipoint spot welding in the main grid line. Soldering heat source for a lamp ( Using the infrared thermal effect) 。 The length of the welding zone about the battery 2 times of length. The extra welding with welding on the back with electrode is connected to the back of the back of the cell. ( Our company USES is the manual welding) 吗? 3, on the back of the concatenated: on the back of the welding is 36 pieces battery concatenated together to form a component list, we are currently using is a manual process, the positioning of the main battery by a membrane panels, there are 36 cell placement groove, groove corresponding to the size of the battery, the size of the slot position has good design, different specifications of the components using different templates, the operator will use the soldering iron and solder wire in front of the battery positive electrode ( Cathode) Welding to behind the back of the battery electrode ( The anode) , which will in turn 36 pieces of concatenated together and across the electrodes in the component list of welding wire. 4, laminating, laying on the back of the combination of good and after inspection, the component series, glass and cutting good EVA, glass fiber, backplane according to certain level, laying for laminated. Glass coating a layer of reagent (in advance primer) To increase the bonding strength of glass and EVA. When laying battery string and glass materials such as the relative position, adjust the distance between the battery, for laminated play. ( Laying levels: from the bottom up: glass, EVA, batteries, EVA, glass fiber, back) 。 5, component layer pressure: laying good batteries placed in laminating machine, through the air in the vacuum components, then heating melt EVA batteries, glass and back glue together; The final cooling components. Laminating process is a critical step in component production, laminated temperature laminating time according to the properties of the EVA decision. We use fast curing EVA, laminating cycle time is about 25 minutes. Curing temperature is 150 ℃. 6, trim: laminated EVA melt after extending outward due to pressure curing formation of burrs, so laminated should be cut. 7, frame: like to install a glass picture frames; To install aluminum frame, glass components to increase the strength of the component, further sealed battery components, extend the service life of the battery. Frame and glass components gaps filled with silicon resin. Use the horn button connection between each frame. 8, welding junction box: lead in welding a box on the back of the components, to facilitate the battery or the connection between the battery and other equipment. 9, high-pressure test: high-pressure test refers to the component frame and between the electrode lead a certain voltage, the test component of the pressure resistance and dielectric strength, to ensure that components in harsh natural conditions ( Lightning, etc. ) Is not damaged. 10, component test: test for the output power of the battery is the purpose of the calibration and test its output characteristics, determine the quality level of components.
