Calculation formula: ring S = π (R?-r?), where ring S = surface size of the solar panel, R is the radius of the outer diameter of the solar panel, and r is the screen LCD.
The power output of solar panels is only related to the area, and the power output has a linear relationship with the area.
Content radius (note: the outer diameter of the LCD screen is 41mm, that is, r is 20.5mm). According to the test data and parameter display provided by the manufacturer, it is necessary to double the area). after two 5530-8L modules are connected in parallel to meet the required current requirement. Ring S = π (R?-r?) = 2*55*30, calculated R = 50.21mm, that is, the outer diameter of the solar panel is 100.5mm.
Detailed information:
1. Battery components should be installed in shaded locations suchonly trees and buildings, and should not be placed near open flames or flammable objects. The assembly structure must be able to adapt to environmental requirements. Please choose appropriate materials and anti-corrosion treatments, and use a strong and reliable method to install components. If the components fall from high altitude, they will cause financial damage. Do not disassemble, bend or hit components with hard objects. Avoid stepping on components and other dangerous actions.
2. Use spring washers and flat washers to lock the entire panel to the bracket. It is best to install the solar panel at an angle of about 30 degrees toward the sun. the condition of the assembly support structure Wire the panel components appropriately.
3. The entire battery panel must be properly connected to thepositive and negative poles of the junction box. The output circuit must be correctly connected to the device. The positive and negative poles cannot be short-circuited. Make sure there is no gap between the connector and the insulated connector, if there is a gap, sparking or electric shock may occur.
4. Frequently check whether the lifting structure has fallen, tighten the components if necessary, and check the connection status of each component, each wire, bottom line and plug.
