Depends on phone battery consumption.
The charging speed of the mobile phone with 5v10w solar energy depends on the power consumption of the mobile phone. If the mobile phone consumes little power, the charging speed will be very fast. The mobile phone consumes a lot of power, the charging speed will be low, this is not necessarily the case.
Solar cells currently on the market mainly use silicon as raw material, which is divided into monocrystalline silicon and polycrystalline silicon. The photoelectric conversion rate is: monocrystalline silicon > polycrystalline silicon > amorphous silicon. For cells made of the same material, the larger the surface area of the solar panel, the higher the power and the greater the output current.
Requirements for solar panels for charging mobile phones
Does the questioner want to ask: "How to charge cell phones with solar charging chairs in the park"? The solar charging chair in the park charges the cell phone as follows:
1. First find the solar charging chair in the park.
2. Then place the phone in the wireless charging area on the chair and the phone will automatically start charging.
3. Finally, the mobile phone does not support wireless charging. You can also use the data cable to charge via the USB interface on the side or under the chair.
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 powere 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. Matching Battery: 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.
