you are right, it is highly unlikely that Voc1 and 2 are same under partial shading. I believe it's just an assumption that was made to simplify the explanation of the graphs.
@@varuncvs7411 can you Clarify the position of Isc1 at 17:17 in both Figure ? In Individual Cell 1 and Cell 2 characteristics - At point - (0,Isc1) - Value of power of cell 1(P1) should be zero ( P=0×Isc1) , but in digram there is a postive power ( shown in red area) I think in i vs V characteristics of cell 1 ➡️ the point mark Isc1 is wrong. Isc1 cannot be at that point . Isc1 should be in more left from the what shown position in diagram in both figure .
Voc1 and Voc2 will be same under shading condition also since it is the open circuit voltage appearing across the cells. It will not depend on shading.
Let's take a practical example, what will happen if I connect 150w module (voc = 18vDC ) and 300w(voc= 36vDC) in series?? Given both panels produces same amount of current.
Excellent explanation sir . Salute
Very informative sir. Thankyou 👏👏👏
it's interesting and learning to watch your videos it, could you do the PV shading simulation and how it affects the solar array...thanks
how will VOC1 and Voc2 will same under partial shading condition

maybe because the Voc is proportional to the logarithmic of ip (that is the insolation) and so the difference between Voc1 and Voc2 is negligible.

current will be same but output voltage gets adds up
Hi sir, can you give me the reference material for these lectures.
thank you nptel
Video part at 17:53 is missing ,so sir please consider it,
Started again after 20:12
