72PCS Perc Double-Sided Double Glass Jdsolar Solar Panels

JDSOLAR double-sided double-glass assembly combined with high-efficiency PERC double-sided battery technology and double-glass assembly structure not only absorbs energy from the front side of the module, but also absorbs reflected light and scattered light from the back side. It has better power generation capability and better low-radiation. Photo performance, and higher reliability.product description

Operating temperature
-40°C~+85°CDouble-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.
According 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.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.
JDSOLAR double-sided double glass components are suitable for flat roof and sun room roofs as well as ground power stations.
