How Much Is The Market Price of Double-Glazed Jdsolar Solar Panels?

At the heart of the solar industry is photovoltaic glass and its battery components. JDSOLAR announced that N-type double-sided double-glass high-efficiency components, which have just been certified by the two IEC standards, are now mass-produced. The 72-position components have the highest front power. At 425W, the component conversion efficiency is as high as 20.7%.The N-type double-sided double-glass assembly introduced this time integrates N-type i-TOPCon double-sided battery, multi-main gate, half-chip, double-glass, double-sided and square single crystal design based on double-sided rate of more than 80%. Low attenuation, low operating temperature and good low light response characteristics can greatly improve the actual power generation performance of the components, and the back of the module can increase the power generation by 5% to 30%. In addition, the N-type double-sided double-glass assembly is highly durable and reliable, and can be extended for up to 30 years.The core of the solar industry is photovoltaic glass and its battery components.
The solar system research institute achieved a laboratory efficiency of up to 25.8% of small-area single-sided TOPCon batteries, setting off a wave of passive contact battery research in photovoltaic academia and industry. The JDSOLAR National Key Laboratory of Photovoltaic Science and Technology pioneered the research on mass-produced TOPCon batteries based on double-sided structures.
 In 2019, JDSOLAR produced a laboratory battery with a frontal maximum efficiency of 24.58% on an n-type substrate of 244.62 cm2 and was certified by the testing laboratory. This is the JDSOLAR National Key Laboratory of Photovoltaic Science and Technology in Photovoltaic Cells. The 19th world record created by conversion efficiency and component output power. In the same year, the average conversion efficiency of JDSOLAR double-sided battery mass production exceeded 23%.Double-sided components, as the name implies, are components that can generate electricity both on the front and back. When the sun shines on the double-sided component, some of the light is reflected by the surrounding environment to the back of the double-sided component. This part of the light can be absorbed by the battery, which contributes to the photocurrent and efficiency of the battery.
Double-sided battery technology
Compared with conventional single crystal cells, double-sided photovoltaic modules can generate electricity under direct sunlight from the front and solar reflected light from the back.
Double-sided double glass assemblyAccording to the packaging technology of the double-sided battery, it can be divided into double-sided double-glass assembly and double-sided (with frame) components. The structure of the double-sided double-glass assembly includes: double-glazed + frameless structure; double-sided (with frame) component adopts Transparent back panel + frame form, etc. The double-glass double-sided component of the mainstream structure has the advantages of long life cycle, low attenuation rate, weather resistance, high fireproof rating, good heat dissipation, good insulation, easy cleaning, and higher power generation efficiency.
Factors affecting power generation gain
The most important factors for the power generation gain of a double-sided component are: surface reflectance and component mounting height. The direct radiation and scattered light from the sun will be reflected when it reaches the ground, and some will be reflected to the back of the assembly.
