The first step taken in the design process was configuring what the measurements that were going to be taken to characterize the solar panels.
With the solar panel placed in the open sun with proper orientation,
the open circuit characteristics of the solar panels in an ideal environment can be measured. With those results,
a 10 resistor is inserted to determine the power characteristics supplied only by the solar panel. The operating manual provided with the system suggested an output voltage of 15V to 23.5V.
