Today, solar energy products are countless, today Shanghai Lian Jie electrical terminal box of solar cells. Its principle is very simple. The role of solar panels to the sun's light energy into electrical energy output DC stored in the batteries.

Component Design

International Electrotechnical Commission IEC: 1215:1993 standard requirements for the design, using 36 or 72 of polycrystalline silicon solar cells in series to form the components of all types of 12V and 24V. The component can be used for a variety of household PV systems, stand-alone PV power plant and grid-connected photovoltaic power plants.

Material characteristics

Polycrystalline silicon solar cells: high efficiency (14.5%) chip package, to ensure sufficient solar panels generating power.
   
: Suede glass of low-iron glass (also called white glass), the thickness of 3.2mm, the solar cell spectral response in the wavelength range (320-1100nm) light transmission rate of more than 91% greater than 1200nm, the infrared light have a higher reflectivity. The solar cell terminal box of glass at the same time resistant to the line of solar ultraviolet radiation, the light transmission rate did not decline.
   
EVA: plus ultraviolet screening agent, the thickness of the antioxidants and curing agents for 0.78mm high-quality EVA film solar cell of the sealant and the connection with the glass TPT agents. Have a high light transmittance and resistance to aging.

TPT: the back of the solar cells covering - fluorine plastic film is white, from the reflection effect of the sun, so a slight increase in the efficiency of the components, and because of its high infrared emissivity, but also reduce the operating temperature of the component solar cell terminal box is also conducive to improving the efficiency of the components. Of course, this fluorine plastic film first solar cell packaging materials requirements of anti-aging, corrosion-resistant, airtight and other basic requirements.
   
Frame: aluminum alloy frame with high strength, resistance to mechanical shock and strong.

The Elinker terminals expert concluded: solar cell terminal box is the most important parts of the solar power system, the conversion rate and service life is an important factor in determining whether a solar cell has a value in use. With the development of science and technology, the solar cell terminal box in our lives will get a larger application.
