Frequently Asked Questions

How can I increase the energy output of my solar panels?

Position the solar panels to face direct sunlight without obstructions or shadows. Install at an optimal angle of 30°-45° for maximum absorption. Clean regularly to remove dust, leaves, or debris for consistent energy output.

How should I connect solar panels to my electrical circuit (series vs. parallel)?

Solar panels can be connected in either series or parallel, depending on your electrical circuit size and power needs. It’s best to connect panels with the same open-circuit voltage.
When connected in series, the voltage (V) increases, while the current (A) stays the same.
On the other hand, connecting panels in parallel increases the current (A), while the voltage (V) remains constant.

Do these panels have pre-drilled holes on the back?

Yes, they do. There are four pre-drilled holes to make installing the solar panel quick and secure.

Can this solar panel be used with a 12V marine battery or a 48V lithium battery?

Yes, it can. The optimal operating voltage of this 100W solar panel is 17.4V, making it suitable for charging a 12V marine battery. For a 48V lithium battery, you’ll need to connect at least three solar panels in series.
Please ensure that you connect the solar panel(s) to a charge controller that supports either a 12V or 48V system.
