Product Description

JDSOLAR solar modules are made of high-efficiency single crystal/polycrystalline solar cells, low-iron ultra-white suede tempered glass, packaging materials (EVA, POE, etc.), functional backplanes, interconnecting strips, bus bars, junction boxes and aluminum alloy frames. composition. The service life can reach 25-35 years.

Single solar cells cannot be used directly as a power source. As a power source, several cells must be connected in series, in parallel, and tightly sealed into components. Solar power

Monocrystalline solar cell module

Solar modules (also called solar panels, photovoltaic modules) are a core part of solar power systems and the most important part of solar power systems. Its role is to convert solar energy into electrical energy, or send it to a battery for storage, or to drive the load. The quality and cost of solar modules will directly determine the quality and cost of the entire system.

JDSOLAR solar module features

High photoelectric conversion efficiency and high reliability; advanced diffusion technology to ensure uniformity of conversion efficiency throughout the film; ensure good conductivity, reliable adhesion and good electrode solderability; high precision wire mesh Printed graphics and high flatness make the battery easy to automate and laser cut.

Transparent battery pack

1 Themes for the generation of laminate components

2 Aluminum alloy protective laminate, which plays a certain role in sealing and support

3 Junction box Protects the entire power generation system and acts as a current transfer station. If the component is short-circuited, the junction box automatically disconnects the short-circuited battery string to prevent the entire system from being burnt out. The most critical factor in the junction box is the choice of diodes. The corresponding diodes are different depending on the type of cells in the module.

4 Silicone sealing function, used to seal components and aluminum alloy frame, components and junction box junctions. Some companies use double-sided tape and foam instead of silica gel. Silicone is widely used in China. The process is simple, convenient, easy to operate, and cost. Very low.

Laminate structure (in process order)

1 tempered glass The function is to protect the main part of the power generation (cell sheet). The choice of light transmittance is required: 1) the transmittance must be high (generally 91% or more); 2) ultra-white tempering treatment

2 EVA is used to bond fixed tempered glass and power generation main body (such as battery sheet). The quality of transparent EVA material directly affects the life of the component. EVA exposed to air is prone to aging and yellowing, thus affecting the transmittance of the component. Therefore, in addition to the quality of the EVA itself, the impact of the assembly process of the component manufacturers is also very large. For example, the EVA adhesive is not up to standard, and the bonding strength of EVA and tempered glass and backing plate is insufficient, which will cause early aging of EVA. Affects component life.

3 Main body of power generation The main function is power generation. The main market in the main power generation market is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages. Crystalline silicon solar cells, the equipment cost is relatively low, but the cost of consumption and cell is high, the photoelectric conversion efficiency is also high, and it is more suitable to generate electricity in outdoor sunlight; thin film solar cells, relatively high equipment cost, but consumption and battery cost Very low, the photoelectric conversion efficiency is lower than that of crystalline silicon cells, but the weak light effect is very good, and it can also generate electricity under ordinary lighting, such as solar cells on a calculator.

4 Back plate function, sealing, insulation, waterproof (usually TPT, TPE, etc.) The material must be resistant to aging. The component manufacturers generally have a warranty of 25 years. The tempered glass and aluminum alloy are generally no problem. The key is whether the backboard and the silicone are Can meet the requirements.

JDSOLAR solar module types

(1) The photoelectric conversion efficiency of monocrystalline silicon solar cells is more than 20%, and the highest is 24%. This is the highest photoelectric conversion efficiency among all kinds of solar cells, because monocrystalline silicon is generally made of tempered glass. And waterproof resin for packaging, so it is rugged and durable, JDSOLAR provides 25 years of quality assurance.

Single crystal flexible solar modules: Flexible solar modules, also referred to as flexible components, are referred to as flexible, meaning that the panels can be bent. The bending angle can reach 30 degrees. Solar modules (also called solar panels) are a core part of solar power systems and are the most important part of solar power systems.

(2) Polycrystalline silicon solar cells The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower, and its photoelectric conversion efficiency is about 18% or more. Polycrystalline silicon solar cells have a shorter lifetime than monocrystalline silicon solar cells. In terms of performance and price ratio, monocrystalline silicon solar cells are slightly better.

(3) Amorphous silicon solar cell Amorphous silicon solar cell is JDSOLAR's new thin film solar cell, which is completely different from single crystal silicon and polycrystalline silicon solar cell. The process is greatly simplified, silicon material consumption is small, and power consumption is small. Lower, its main advantage is that it can generate electricity in low light conditions.
