Yes, you can connect multiple panels in parallel to increase current (amps) or in series to increase voltage (volts), depending on your charge controller's specifications.
The panel is designed for standard mounting, but specific brackets or hardware are typically sold separately to accommodate various installation surfaces.
Yes, the module is designed for outdoor use and is weather-resistant; however, connections and the charge controller should be kept in a dry or protected environment.
A 10A or 20A PWM or MPPT solar charge controller rated for 12V systems is recommended for a 120W panel.
Monocrystalline panels are highly durable and are typically rated for 20-25 years of operational life with minimal performance degradation.
Ensure the panel is not partially shaded and check for dirt or debris on the glass surface.
Check the connections between the solar panel and the charge controller, and verify that the charge controller settings match your battery chemistry.
To set up your GWSOLAR panel, mount it securely to your chosen surface, ensuring adequate airflow beneath the frame to prevent overheating. Connect the panel leads to a compatible 12V solar charge controller using appropriately sized solar cables; the controller is essential to prevent overcharging your battery. For ongoing care, clean the glass surface periodically with water and a soft cloth to remove dust, pollen, or bird droppings that could block light transmission. Avoid using abrasive cleaning agents or harsh sponges that may scratch the anti-reflective coating on the glass.
