Product Description

Factory Direct A Grade 72 Cells 340w Polycrystalline Poly Solar Panel For Solar System

1. Product Description

Crystalline silicon solar panels are mainly divided into polycrystalline and single crystal two, many people do not know what the difference between the two in the end, often in the purchase of the difficulty.So, what are polycrystalline and single crystal panels?HeSheng Xiaobian today for you to explain the difference between polycrystal and single crystal solar panels, together to understand it.

(1) appearance difference

Polycrystalline solar panels from the appearance of the above words, the four corners of the single crystal solar panels appear arc shape, no pattern on the surface.Single crystal panels all look the same on the surface.

The four corners of the polycrystalline panels show square angles, with patterns, polycrystalline and polycrystalline less color, like the snowflake crystal pattern on the tin, light blue.The surface of the polycrystalline panel looks like there is a lot of broken glass inside, shining.

(2) the difference of manufacturing technology

Monocrystalline silicon and polycrystalline silicon of the difference between their atomic structure arrangement, single crystal is orderly arrangement, polycrystalline is disordered arrangement, this is mainly decided by their processing technology, polycrystalline casting method is used to produce more, is the silicon material in crucible melting, directly to the Siemens modified czochralski method and single crystal is adopted to draw process is a process of atomic structure reorganization.

The manufacturing process of polycrystalline solar panels consumes about 30% less energy than that of single-crystalline solar panels, so polycrystalline solar panels account for a larger share of the world's total solar panel production and are less expensive to manufacture.

(3)use difference

Single crystal solar panel Single crystal solar panel is a kind of solar cell developed rapidly at present. Its composition and production process have been finalized. The products have been widely used in space and ground facilities.This kind of solar cell takes the high purity single crystal silicon rod as the raw material, the purity requirement 99.999%.The photoelectric conversion efficiency of single crystal solar panels is about 15%, and the high efficiency is up to 24%. This is the highest photoelectric conversion efficiency among the current types of solar cells. However, the production cost is too high to make it widely and universally used in large numbers.Because the single crystal panel is generally sealed with toughened glass and waterproof resin, it is strong and durable, and its service life can generally reach 15 years, up to 25 years.

Although the average conversion efficiency of single crystal panels is about 1% higher than that of polycrystalline panels, because single crystal panels can only be made into a quasi square (four sides are arc-shaped), there will be a part of the area when forming solar panels to fill up;Polycrystals are square, so there is no such problem.The photoelectric conversion efficiency of polycrystalline solar panels is about 12%.In terms of production cost, it is less than that of monocrystalline silicon solar cells. The materials are simple to manufacture, and the power consumption is saved. The total production cost is lower.

The above is the difference between polycrystal and single crystal solar panels, hope to help you to have more understanding of these two kinds of solar panels.For users, single crystal panels and polycrystalline panels are not too big of a difference, their life and stability are very good, you can choose according to their own actual use of solar panels with higher comprehensive benefits.Luoyang Hesheng PV Co., Ltd. R & D, production and sales of a variety of photovoltaic modules, single crystal and polycrystalline solar panels are complete, excellent performance, according to customer needs for high quality special customization, welcome interested to come to consult.

2. Solar panel composition and functions of each part:

(1) toughened glass: its role is to protect the main body of power generation (such as battery)

(2) EVA: used to bond and fix toughened glass and the main body of power generation (battery)

(3) Battery: The main function is to generate electricity -- crystal silicon solar cells and thin film solar cells

(4) Backboard: function, sealing, insulation and waterproof.

(5) aluminum alloy: protective laminated parts, play a certain sealing, support role.

(6) junction box: protect the whole power generation system, play the role of current transfer station.

(7) silicone: sealing function, used to seal components and aluminum alloy frame, etc
