How to Test Solar Panels: Output, Amps & Watts
2. Compare the panel''s Imp to your current reading. Your current reading should be in the ballpark of the panel''s current at max power, but by no means does it have to be identical. The current I measured was 5.24 amps and my panel''s Imp is 4.91 amps, so I know my panel is working properly!
Understanding the Voltage – Current (I-V) Curve of a Solar Cell
For getting the maximal power out of the module, it thus is imperative to force the module to operate at the maximum power point. The simplest way of forcing the module to operate at the MPP, is either to force the voltage of the PV module to be that at the MPP (called Vmpp) or to regulate the current to be that of the MPP (called Impp).
