Solar panels have off color will have an impact on solar street light?

- -

often have customers ask me why do solar panels have off color, if use the c-class, worried about have off color panels have quality problem, the following our street lamp factory is aimed at this problem, for everybody.

a, why don't panels color consistent

the color of the solar panel is mainly to velvet. Red piece of cloth with soft nap is mainly due to the system due to corrosion in oil, if system corrosion amount is lower than cashmere, and the damage layer of silicon will remove not thoroughly, cause PE coated color red as a whole. The so-called flower piece, it is caused because of the excessive amount of corrosion system velvet, generally down, 'said the velvet corrosion amount above. When the silicon is equivalent to the polishing processing, glossy coating after cell, grain boundary is more obvious.

for Yin and Yang, can be divided into the following two conditions: one is immersion situation; The second is the way between corrosion amount have deviation. Immersion problem is in the process of production, affected by the level of front and rear wheel and the front baffle, silicon wafer in into the velvet tank, liquid silicon lag in contact. This liquid silicon first contact area after corrosion amount will higher than the liquid contact area. The corrosion quantity differences inevitably lead to suede silicon wafer surface effect is not consistent, PE coated will produce certain color difference. In order to guarantee the effect of immersion, need to adjust system velvet slot roller and baffle.

and common appeared color deviation is polycrystalline silicon cell, for polycrystalline silicon cell, dark blue is the color of the most common, monocrystalline silicon is black. Through process adjustment, the color deviation problem can be effectively solved.

2, qualified panels also have off color

because using the coated glass, as long as the use of coated glass can hardly avoid such a situation. The same batch of coated glass at the time of outgoing and incoming inspection look not to come out, even to make components after all look not to come out, only after the installation, in certain Angle and the light can be found.

there is a glass of hydrophilic might be the problem, when we test found that use different manufacturer of coated glass, hydrophilic ability is different, rain or fog, dew difference is quite big, therefore the phenomenon of components in the different colors. General component is slightly off color is normal, but if it is a board has a variety of color is the product quality has a problem. General photovoltaic products in the factory, each component are through the strict inspection, can be at ease use.

3, the color will affect the output of solar street lamps and life?

although the use of color is not consistent with the pv array, will affect the overall appearance, customers in the psychological is not easy to accept. But the simple fact panels color difference will not affect electricity production and life, the factors influencing capacity is mainly shortcomings, such as crack, and color difference just process problems, so it is will not affect the solar street light photovoltaic power generation and the life of the component.

in all panels, solar street lamps have off color is normal phenomenon, craft that cannot be avoided, but you please rest assured that the buyers also have color difference don't affect the service life of the solar street light and power generation efficiency, please rest assured to buy!
