this is the first youtube video having no "thumbs Down" and i wish never shall be a "thumbs down" ever. Very good explanation for solar cell equivalent circuit. It seems umanand sir, has retired from iisc bangalore.
I don't know what I would of done in my 1st year at Uni without you. I am now in my 2nd year and asking myself the same question. A MASSIVE THANK YOU - YOU ARE LOVED
Beautifully explained SIr... Very informative and finally I understood the equivalent circuit of the solar cell. Thanks for making such a factual video with a simple explanation.
very good explanation ,easily understand the concepts and inherent operation of pv system .thank you sir .sir if possible Explain about robust controller for solar pv system belongs to the uncertainty.
Sir, why you started with the PV relation of a simple diode ? what is the necessity of this PN diode curve ? why did not you started directly with the PV cell circuit ? in the PV cell equivalent circuit, what does the parallel diode represents ?
Sir one question arriving that if diode is placed in parallel to current source than when diode is in forward mode it should short-circuit the path. Why current is flowing further.??
Dear Kishan, One explanation could be , the diode is having its internal resistance which can be very less resulting in maximum current being flowing through diode & rest current to the output load. That is why you can see the Voltage is reflected higher at the output port due higher drop at diode and current will be less at the output terminal. You can figure this out from the PV module specification of any brand , you will get to know that Voltage is much higher as compared to current . For instance , 365 Wp module having 72 cells have 40V Max Voltage & 9A Max Current. Hence the query that diode in connection with current sources resulting S.C is not practically possible otherwise the theory of solar PV would have been failed. Hope you got some idea !!!
@@sunilrtripathi4670 perfect explanation by Sunil sir . From today I will not forget your explanation. I have referred many Google site's even books but today I got perfect answer
Thanks for the vey helpful explanation. Could you tell which is the software/application used to draw the graphs and edit them? It is a really didatic tool.
There's a jump in reasoning when resistances are introduced. It is either "real diode" or "ideal diode + 2 resistors". Leaving the diode as it is and adding resistors makes no sense. Otherwise very good lecture and I know what I'm talking about having two degrees in electronics and electrical engineering. I'll watch a lot from this lecturer in the near future.
hello sir, i really love the work you're doing here. I have a request, im working on DSSC, and i want to understand its equivalent circuit through electrochemical impedance spectroscopy
Great video. Only question I have is regarding the resistances you included in the circuit. What is the logic in assuming those impedance? For instance, whether or not you place a shunt resistance as you show here, what difference does that make? Thank you
