4. Backplane
Used as a backside protective packaging material, commonly used are divided into T door, TPE and PET, polyethylene structure. It is used to enhance the aging resistance and corrosion resistance of photovoltaic modules, and extend the service life of photovoltaic modules; the white backplane scatters the light incident into the photovoltaic module, which improves the light absorption efficiency of the photovoltaic module, and at the same time, because of its high The infrared emissivity can also reduce the working temperature of the photovoltaic module; at the same time, it improves the insulation performance of the photovoltaic module.
5. Tempered glass
It is used to support the structure of photovoltaic modules, enhance the load-bearing and load-bearing of photovoltaic modules, and has the functions of light transmission, anti-reflection, light transmission, water blocking, gas blocking and corrosion prevention.
6. Aluminum frame
The aluminum alloy frame of the glass epitaxial installation plays the role of protecting the edge of the glass, strengthening the sealing performance of the photovoltaic module and improving the overall mechanical strength of the photovoltaic module, which is convenient for the installation and transportation of the photovoltaic module.
7. Silica gel
Used for bonding and sealing laminated glass photovoltaic modules, bonding junction boxes and backplanes, and enhancing the UV resistance of photovoltaic modules.
8. Junction box
The electrical connection device of the photovoltaic module plays a role of sealing and waterproofing the lead wire of the photovoltaic module, and protects the safety of the photovoltaic module system during operation.
Due to the low output voltage of monolithic solar cells, and the fact that the electrodes of unencapsulated cells are easy to fall off due to the influence of the environment, a certain number of monolithic cells must be sealed into solar cell modules in series and parallel to avoid battery electrodes and mutual The wiring is corroded, and the packaging prevents battery breakage, which facilitates outdoor installation. The quality of the packaging determines the service life and reliability of the solar cell module.
So solar panel component materials includes solar cells, tin-coated copper tape, EVA, backplane, tempered glass, aluminum frame, silica gel and junction box. All those components enable solar panel turn sunlight to electricity to light up all solar led lights outdoor like Motion Sensor Solar Street Light and solar flood light.
