Solar charging power is relativley low

Note: The nominal power is the ideal laboratory data, which is actually affected by the irradiation angle, light intensity, air quality and temperature.

Troubleshooting steps:

① Adjust the solar panel to the best irradiation angle (90°).

② Clean the dust on the board surface and remove the shelter.

③ Check whether the voltage matches when multiple boards are connected in series. It is recommended to use the same type of solar panels in series.
