What are the main packing material of solar panel component? Which of the

Solar panels are made according to the different requirements of users for the power and voltage of the solar battery components can be a single use, can also be passed by a number of solar cell components in series ( To satisfied voltage requirements) And in parallel, To satisfied with the current requirements) Constitute the power supply square for

solar panels is according to customer's demand for power and voltage of different manufacturing solar cell module, which can be used alone, and you can also by forming series ( With satisfactory voltage requirements) And in parallel, It has satisfactory current demand) Several of the power of the solar cell module matrix to provide more power. The life of the solar panel component is closely related to the packaging materials and packaging technology. The main packaging materials including cell ( Now describe) , glass, ethylene - Vinyl acetate copolymer, thermoplastics, aluminum alloy frame, junction box, etc. 1. The thickness of the glass: 3. 2 mm low iron ( Main influence brittle glass) Toughened glass in corresponding to the solar spectral wavelength range ( 320 - 1100 nm) Inside the light transmittance is greater than 91%, resistance to ultraviolet radiation, light transmittance is not falling. Parts made of tempered glass is acceptable to 25 mm in diameter, velocity of ice hockey is 23 meters/SEC. 2. EVA: high quality of 0. 5 mm thick EVA film layer is used as a solar battery sealant and connection with glass and thermoplastic polyurethane. It has high light transmittance and anti-aging ability. 3. Frame: selection of high strength aluminum alloy frame, mechanical shock resistance ability. 4. TPT: the opposite of a solar cell, basic requirement for ageing resistance, corrosion resistance, resistance to ultraviolet radiation, air tightness and so on.
