Installation instructions and installation methods of solar panels
The role of the solar panels is the sun's light energy into electrical energy, the output DC into the battery. Solar panels are one of the most important components in solar power generation systems. Their conversion rate and service life are important factors in determining the usefulness of solar cells. Using 36 or 72 polycrystalline silicon solar cells in series to form 12V and 24V of various types of components. The module can be used for a variety of household photovoltaic systems, independent photovoltaic power plants and grid-connected photovoltaic power plants. Characteristics of raw materials Battery: High efficiency (more than 15.5) of polysilicon (16.5 or more monocrystalline silicon) solar cell package to ensure sufficient power generation of solar panels. Glass: the use of low-iron steel velvet glass, also known as white glass, the thickness of 3.2mm in the solar cell spectral response wavelength of 320-1100nm transmittance of 91 or more, for greater than 1200nm infrared light has a high reflectivity. The glass at the same time the ability of the sun's ultraviolet light radiation, light transmission rate does not decline. EVA: Addition of a UV-resistant agent, antioxidant and curing agent thickness of 0.78mm high-quality EVA film as a solar cell sealant and glass, TPT between the link agent. Has a high transmittance and anti-aging ability. TPT: the back cover of solar cells - fluorine plastic film is white, reflecting the role of the sun, thus improving the efficiency of the component slightly, and because it has more
High infrared emissivity, but also reduce the operating temperature of the components, but also help improve the efficiency of components. Of course, this fluorine plastic film with solar cell packaging materials required first anti-aging, corrosion resistance, airtight and other basic requirements. Border: The aluminum alloy frame with high strength, anti-mechanical impact capability. Basic parameters Standard test conditions: (AM1.5) Irradiation 1000W / m2 Battery temperature 25 ℃ Insulation voltage: ≥600V (≥ 1000V above 100W) Frame grounding resistance: ≤10hm Upwind pressure: 2400Pa Filling factor: 73% Short circuit current Temperature Coefficient: 0.4mA / ℃ Open-circuit Voltage Temperature Coefficient: -60mV / ℃ Operating Temperature: -40 ℃ ~ 85 ℃ Component Wiring Instructions Installation Tools M4 screwdriver, Phillips screwdriver. Opening the terminal box cover Insert the M4 flat-blade screwdriver into the mounting hole on the cover according to the label on the terminal box and lift it gently so that the four corners of the door are lifted. . There are wiring cover inside the box, to lift it can see three terminals. Battery panel wiring in the left and right next to the two terminals have positive and negative signs, it represents the battery in the working state of the output voltage of the positive and negative, in accordance with the positive needs of positive power then negative, then negative. Use mechanical clamping method, with M4 Phillips screwdriver to tighten the terminal screw screw, the wire is peeled through the G7 cable seal connector, insert the wiring hole, the line pressure. After the wires are connected, cover the protective cover. Screw the self-tapping screw into the screw hole with M4 Phillips screwdriver. After the cover is fixed, complete the wiring of the panel. Grounding the Battery Pack Grounding screws are installed on the back of the battery pack. Secure the grounding wire to the grounding screw.
