The Eflex solar panel can charge most batteries (charge controller needed) and power stations. However, please ensure that the open circuit voltage of the panel does not exceed the max DC input voltage rating of the powerstation or charge controller

Several factors may be impacting the performance of your solar panel. Typically, indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass lead to a reduced power output.

Depending on your electrical circuit size and power demand, solar panels can be connected in series or in parallel. When you connect them in series, the system current output will be the same as that of a singular panel, while producing the effect of adding up their operating voltage output. On the other hand, the operating current output of individual panels is added up to be the system output current when they are connected in parallel. In this case, the system output voltage will be the same as the output voltage of one solar panel. To meet the optimum power output and system rating for your power system, you can use both parallel and series connections.

To figure out how many solar panels you need, you must define the required power load. Power is measured in Watt, and capacity is commonly measured in Watt-hours (multiply power output in watts by the required number of hours of operation multiplied by a safety factor of 1.5-2). As such, first figure out your battery bank based on the minimum required capacity, and then decide how many panels or how much power input is needed.
