    Im going to do project on solar dc energymeter
    The current and voltage from solar panels are to take directly..how is it possible.
    how is V & I take from panel??
    It is then given to energy chip from ther output is stored in PIC and display
    Review is approaching
    What all basic things i ve to know..it 's zeroth review so 've to explain jst about what to do
    What is the bavkground of this project??
    and methodology..

    The background appears to be that you have done nothing so far and you are panicking now that it is time for a review.

    Your methodology seems to be to ask for someone else to do the work that you have neglected to do.

    Seriously... How do you think you measure voltage and current?

    A more important issue though is how do you ensure that these results are actually meaningful. You may want to google MPPT.

    For an early review, you may be able to get away with some hand waving explanation about PICs and LCD displays.

    Just don't bite off more than you can chew. You need to at least have a basic understanding about how you could achieve the things you plan to do.

    Using LEM sensors V&I can measure
    I've idea about this..nt enter into the practical side ..
    thas wht asking guidance or help of the experienced persons like you..

    ya..max power poin tracking..at that point gt the max power..
    in solar depends on the intensity of radiation/light..

    THEN??

    yes...

    yes, but that isn't the point. What does MPPT do?

    Go back and read what MPPT is. Then see if you can see how it might be applicable (even essential) to your project.
