Product Features:
1 high-efficiency crystalline silicon solar cells, solar panels to ensure peak in the power can provide enough power.
2.solar cells coated with silica coating can effectively prevent the reflection of sunlight, thus improving the photoelectric conversion efficiency of solar panels up to 17%.
3 lamination technology: quartet built a total of five layers from top to bottom as follows: glass, EVA, solar cells, EVA, back. Can ensure the production of high mechanical strength, waterproof, anti-corrosion, anti-vibration, anti-distortion, high-quality solar panels, life for 25 years.
4 glass: the use of ultra-low carbon steel white glass with high light transmission, waterproof, high mechanical strength, often times do not change color characteristics of ultraviolet radiation, the effective protection of solar cells.
5.EVA: EVA plus a UV agent and curing agent, autoclave cured to form a flexible protective layer, and make solar cells and glass back in close contact with these three parts, the whole forming a waterproof seal, to protect solar board effect.
6 back: the use of TPT board, light, moisture, corrosion effect.
7 aluminum frame: tinned oxidation, anti-distortion aluminum alloy frame, an increase of mechanical strength of solar panels, so that it can in any harsh environment to work properly.
8. Junction Box: Junction box attached to the back of solar panels, solar panels leads to the electrodes for connection to external electricity products. Easy to disassemble, almost no local maintenance. When the solar panel power is large, the slip in the junction box built-in diode to protect high current circuits are not burned.
9 according to customer needs with solar panels and solar panel wire holder.
