A solar panel, also known as a photovoltaic (PV) panel, is a device that converts sunlight into electricity through the
photovoltaic effect. Hereâ??s a detailed description of solar panels:
Structure and Components
1. Photovoltaic Cells:
* Solar panels are made up of multiple photovoltaic cells arranged in a grid-like pattern on a rigid frame.
* Each cell is typically made from silicon, the most common semiconductor material used in solar panels.
2. Encapsulation:
* Photovoltaic cells are encapsulated between a front glass cover and a backsheet or encapsulant material.
* The front cover is tempered glass designed to protect the cells from environmental factors while allowing sunlight to pass through.
Features of Dwell s EPE(EVA/POE/EVA) solar film extrusion line:
Film Layers structure: According to the finished film, EVA/POE/EVA film has three layers(EPE film). It will be based on the customer requirements, EPE solar film extrusion line can also produce EVA or POE single layer.
China EVA / POE / EPE solar film is used for solar cell encapsulation. After lamination and curing, it is bonded and sealed. It plays the role of high light transmittance, preventing water vapor penetration, high and low-temperature resistance, and ultraviolet light resistance to ensure the stable and efficient use of battery modules. It is a durable and reliable packaging material. The EVA / POE / EPE packaging film extrusion line of Dwell machinery is in a leading position in the world.
Advantages of the Dwell EPE(EVA/POE/EVA) solar film extrusion line
If producing EPE film, the line speed of the EPE solar film extrusion line can reach 12m/min-15m/min, if EVA, can reach15-18m/min, and if POE, can reach 10-13m/min.
Cooling parts to ensure shrinkage rate is less than 3%.
DWELL special winder to ensure micro-tension, and achieve automatic winding and cutting.
Comparison of the Dwell EPE(EVA/POE/EVA) solar film and EVA solar film and POE solar film
1.Transparent EVA solar film: with high light transmittance, it is used for bonding glass and cells; The raw materials are EVA resin and various modifiers, which are cheaper.
2.White EVA solar film: compared with transparent EVA solar film, the pretreatment of white fillers such as titanium dioxide is added. It has a strong barrier, low light transmittance, and high reflectivity, which can improve the power generation of components. It has strong resistance to damp-heat aging and ultraviolet aging and can inhibit the aging and cracking of the back sheet.
3.Poe solar film: Poe solar film has a higher water vapor barrier rate and stronger anti-PID performance so the module can be used for a long time. It is the main packaging adhesive film of a double-sided double glass module and film module at present. 4.EPE(EVA/POE/EVA)solar film: It has both the anti-PID performance of POE and lamination efficiency of EVA solar film and reduces the use of POE particles to achieve cost reduction and efficiency increase. At present, it is mainly used in high-efficiency components.
