No.
From a query on NetEase, we learned that a solar panel is a device that responds to light and converts light energy into electrical energy. Solar panels can theoretically charge with any light, but light that is too dim or lighter in color will have poor or even undetectable effects.
1. Power size: Choose the appropriate power according to your own electricity needs. If it is used to charge mobile phones and small devices, the power should be between 5W and 20W; large devices such as vehicle-mounted cranes, its power should be higher.
2. Output Voltage: Different devices require different voltages for charging. Therefore, when choosing a solar panel, pay attention to whether its output voltage meets the requirements.
3. Corresponding batteryspondante: To store solar energy, when purchasing a matching battery for a solar panel, note that the battery capacity and rated voltage must match the solar panel.
