Solar panel on solar shield V.2.2

Post by icnmfabro » Wed Jun 27, 2018 12:39 am

I have a solar panel with these characteristics:
1) Maximum Power: 4W
2) Open circuit Current (Voc): 7.2V
3) Short Circuit Current (ISC): 0.72A
4) Maximum Power Voltage (Vmp): 6V
5) Maximum Power Current (Imp): 0.66A
6) Maximum System Voltage: 1000VDC

I would like to know if with these parameters I could use it on a solar shield V2.2 or if I burn the shield because it has the characteristics too high.

Thank you.

Hi:
What does the open circuit current mean? Open circuit will not exist current only voltage. In addition to the second parameter, I checked the Solar Charger Shield v2.2 's parameter, the solar panel is suitable.

Hi ...
Yes ... my mistake in typing ... in fact it is Open circuit Voltage (Voc) which is 7.2V., So even if the "Voc" has a voltage slightly higher than 6V the panel can be used without risk and danger from SeedStudio Arduino Solar Shield V. 2.2?
Can you confirm it? Thanks for your help. :) :) :) :)

Dear Costumer:
Open circuit voltage and short circuit current are used to calculate solar panel's equivalent resistance.You just need concentrate maximum power current and maximum power current.According to your picture's parameter, the solar panel is suitable.
