4. Setup and Installation
The ACOPOWER 25W solar panel is designed for straightforward installation. It requires a solar charge controller (not included with the panel itself, but available separately) to regulate the power output and protect your battery from overcharging.
4.1 Unboxing and Components
Upon unboxing, you will find the solar panel and an instruction manual. The panel features positive and negative cables, typically ending in alligator clips for direct connection to a charge controller or battery (with appropriate safety measures).

4.2 Connecting to a Charge Controller
A solar charge controller is essential for any solar power system to prevent battery damage. Connect the positive and negative cables from the solar panel to the corresponding solar input terminals on your charge controller. Ensure correct polarity to avoid damage to the panel or controller.
For detailed visual instructions on unboxing and connecting the solar panel to a charge controller, please refer to the official product video below:

4.3 Mounting Considerations
Choose a mounting location that receives maximum direct sunlight throughout the day, free from obstructions like trees or buildings. The pre-drilled holes on the panel's frame allow for secure attachment using compatible mounting hardware (e.g., Z-brackets, pole mounts, tilt mounts). Ensure the panel is angled correctly for optimal sun exposure based on your geographical location and season.

5. Operating Instructions
Once properly installed and connected to a charge controller and battery, the solar panel will automatically begin generating power when exposed to sunlight. The charge controller will manage the charging process to ensure the battery is charged efficiently and safely.
- Optimal Performance: For best results, ensure the solar panel is clean and free from dust, dirt, or debris. Any obstruction on the panel surface can reduce its power output.
- Monitoring: If your charge controller has a display, monitor the charging status and battery voltage regularly to ensure the system is functioning as expected.
- System Expansion: For higher power requirements, multiple ACOPOWER solar panels can be connected in series or parallel, depending on your system's voltage and current needs. Consult a qualified technician or the charge controller manual for proper wiring configurations.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ACOPOWER solar panel.
- Cleaning: Periodically clean the surface of the solar panel with a soft cloth and mild, non-abrasive cleaner to remove dirt, dust, and other debris. Avoid using harsh chemicals or abrasive materials that could scratch the glass.
- Inspection: Regularly inspect the panel for any physical damage, such as cracks in the glass, bent frames, or loose connections. Check the wiring for any signs of wear, fraying, or corrosion.
- Connections: Ensure all electrical connections are secure and free from corrosion. Loose connections can lead to power loss or system malfunction.
- Obstructions: Keep the area around the solar panel clear of any shading obstructions, such as tree branches or accumulated snow, which can significantly reduce power output.
7. Troubleshooting
If your solar panel system is not performing as expected, consider the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | No sunlight, panel dirty, loose connections, faulty charge controller/battery. | Ensure direct sunlight, clean panel, check all connections, test charge controller/battery. |
| Low power output | Partial shading, dirty panel, incorrect panel angle, high temperature. | Remove shading, clean panel, adjust panel angle, ensure proper ventilation. |
| Battery not charging | Faulty charge controller, battery issues, incorrect wiring. | Verify charge controller operation, test battery, check wiring polarity. |
If issues persist after attempting these solutions, please contact ACOPOWER customer support for further assistance.
