1. What can this panel charge?

The Eflex solar panel can charge most batteries (charge controller needed) and power stations. It is important to ensure the the open circuit voltage of the panel will not exceed the max DC input voltage rating of the power station or charge controller.

2. Why is my solar panel under producing?

Solar panel performance may be hindered for a number of reasons; such as indirect sunlight, temperature rise, cloudy sky, dirt and stain build up on the top of the glass.

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

Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demand. Connecting solar panels in series will have the effect of adding up their operating voltage output, while the system current output will be the same as that for one panel. While connecting solar panels in parallel will have a different effect; individual panels operating current output will add up to be the system output current, while system output voltage will be the same as the output voltage of one solar panel. Please make sure the open circuit voltage of the connected panel will not exceed the Max DC input voltage of the power station or charge controller.

4. How many solar panels do I need?

The best way to gauge how many solar panels you need is to understand and define the power load needed from this system. Power is measured in Watts and Capacity is commonly measured in Watt-Hours (multiplying power output in watts by the required number of hours of operation multiplied by a safety factor of 1.5-2). Therefore, it is wise to size your battery bank first based on the minimum required capacity, and accordingly decide how many panels or how much power input is needed.
