Introduction Parameters of solar panel output power 2W/12W 2 (W) operating voltage 9 (V) conversion efficiency 16.5 (%) fill factor 80 (%)

2W/12W solar panel parameters

Output power 2 (W)

Operating voltage 9 (V) Conversion efficiency 16.5 (%)

Fill factor 80 (%) Operating current 0.22 (A)

Open circuit voltage 10.6 (V) Short circuit current 0.25 (A)

Outline size 180*140*17MM Weight reference 0.6 (kg)

Output power 12W (W)

Operating voltage 16.4 (V) Conversion efficiency 16.5 (%)

Fill factor 76 (%) Operating current 0.88 (A)

Open circuit voltage 21.6 (V) Short circuit current 1.06 (A)

Outline size 465x295x25mm Reference weight 1.2 (kg)

The main reason is that the solar panel has a certain internal resistance,

The circuit voltage open is equivalent to directly taking a voltmeter to measure the voltage at both ends of the battery board (which can be regarded as a DC power supply).

The peak voltage is the voltage after pen chargingduring operation. Since there is a voltage divided into load, how can it be greater than the open circuit?
