If the solar panel output is abnormal or the power generation is lower than expected, the main possible causes include:
1. Sunlight intensity, duration, and installation environment
The position and angle of the solar panel directly affect power generation.
2. Surface dirt on the solar panel
Dust, dirt, or debris on the panel surface can reduce charging efficiency.
3. Damage from drops or external impact
Physical damage due to dropping or external force may reduce the panel’s output.
4. Power Station remaining battery level
Our Power Stations use CCCV charging (Constant Current – Constant Voltage). When the battery approaches full charge, the system automatically limits the input power from the solar panel, causing the charging rate to gradually decrease.
5. Solar panel malfunction
Internal faults or aging from long-term use may also reduce power output.
To help accurately identify the cause of reduced output, please assist with the following:
1. Test under proper conditions
1) On a sunny day (recommended between 12:00–14:00), place the solar panel outdoors in direct sunlight.
2) Ensure the Power Station’s remaining battery level is below 50%.
3) Check whether the power output reaches 24W or above.
2. Provide installation photo
If the output is still below 24W, please send a clear photo showing the solar panel installation and how it is connected to the Power Station.
3. Confirm panel history
Please let us know if the solar panel has ever been dropped or subjected to strong impact.
