    Nick,, do a video on panel output verses load applied. most panels out there are poor power sources and the public needs to know how they are getting ripped off. OCV and short circuit current is a poor way to rate a power source. I can’t remember any generator company rating a generator under theoretical power. The net is full of advertisements claiming 100W 12V solar panels which will never give you anything near that rating. I was an engine generator instructor for years and am lost as to how This theoretical data slips into the wattage rating of a panel when those conditions will never be there in the real world.
    Oh well, guess I’m just an outdated old dummy

    *This book [link here>>>**t.co/ejytdVx2sh** ] got me thru the design and installation of a complete off-grid system for my lake cottage. The process of site evaluation, system component selection, wiring, etc. is complex, but with a lot of study and this book, I ended up very happy with the results. Everything you need to know is here. I recommend it for anyone who is starting with little solar panel knowledge and wants to end up with a whole house system*

    Clear as mud. Poor explanation on temperature. If you can’t understand, don’t confuse the rest of us. thumb down icon.

    Interesting video and excellent explanation. Thanks

    What a nice explanation

    Cheers for the video content! Apologies for butting in, I would love your opinion. Have you thought about – Schallingora Computer Reconstruction Scheme (should be on google have a look)? It is a good one of a kind guide for saving money using this smart solar power trick minus the hard work. Ive heard some super things about it and my close friend Aubrey after many years got cool results with it.

    Can anyone explain me the physics backround in decrease of effieciency in PV cells when the temperature increases? According to physics, higher temperature in semiconductors generates more free electrons so why is there a decrease in efficiency?

    Thank you 🙂

    Awsome Video! Thank you so much 🙂

    Good evening! My name is Francesco and I’m doing a thesis on floating photovoltaic panels.
    I’m looking for a relationship between the resistor Rs that appears in the equivalent circuit and the temperature. This is to see how the resistance value varies at different temperatures and consequently evaluate the efficency . Can anybody help me? Thanks in advance to anyone who wants to help me!

    Better content…with touch of mathematical modelling …super

  14. shivam kumar on April 28, 2021 at 1:09 am

    Good enough

  15. Peg Dimarco on April 28, 2021 at 1:09 am

    Take some info about energy on Avasva . It was very helpful to me 😀

  16. MSA on April 28, 2021 at 1:10 am

    Can we calculate solar electricity production from weather data or what are the parameters that are required to calculate the solar electricity production ?

    Nice

    Which is the difference between an EQE to a IQE

    Nice explanation

  21. Nah Z on April 28, 2021 at 1:20 am

    Thank you a lot! Everything is crystal clear!

  22. John Gilmour on April 28, 2021 at 1:23 am

    would rotation of the solar cell to capture energy allowing it to not get too hot? removing one element of energy loss, affecting other elements of loss?

  23. Garry Superales on April 28, 2021 at 1:24 am

    But how do we get the power input?

  24. Ibrahim Mujičić on April 28, 2021 at 1:28 am

    Nice explanation, thank you!
