The secret of solar panels, small solar street lamps resist aging

Attenuation refers to the aging in the long-term use of extremely slow power decrease, the main reason about battery slow attenuation, are also associated with packaging material performance degradation. Which the ultraviolet irradiation is a major cause of lead to component advocate material performance degradation.



aging attenuation refers to the use for a long time in the extremely slow power decrease, the main reason about battery slow attenuation, are also associated with packaging material performance degradation. Which the ultraviolet irradiation is a major cause of lead to component advocate material performance degradation. Long-term exposure to the sun's ultraviolet rays, EVA 【 Eva can refer to an evangelion anime series, can also refer to Eva all the body. 】 And the back ( TPE【 TPE（ 热塑性弹性体) Is a kind of thermoplastic elastomer material, high strength, high elasticres ilience, injection molding processing characteristics, application scope is widespread, environmental non-toxic safety, have excellent coloring. 】 Structure) Degradation and yellowing phenomenon, resulting in a decline in component light transmittance, resulting in power down. This requires component manufacturers in the choice of EVA and the backboard, solar led street lamp' Based energy as the earth's resources increasingly poor, the investment cost of the surging, all kinds of safety and pollution hidden danger is everywhere, the solar energy as an 'inexhaustible, an inexhaustible' safety, environmental protection, new energy more and more attention. 】 Manufacturers must be strictly controlled, the selected material must be very good performance in the ageing resistance, to reduce the power attenuation caused by complementary material aging component.

solar panel price component quality problem caused by attenuation

solar panel prices components in some common quality problems in the process of production, is the leading cause of components in the process of generating power attenuation. Common quality problems mainly has:

component receives the silicone, EVA residues are not cleaned, outdoor dust adhesion, easy to cause damage of hot spots.
