Relating solar energy area to power/time?

  1. Feb 24, 2008 #1
    1. The problem statement, all variables and given/known data

    Given Information:

    At midday, solar energy strikes the earth with an intensity of about xxxW/m^2

    Question:

    What is the area of a solar collector that could collect xxxMJ of energy in xxxHours ?


    2. Relevant equations



    3. The attempt at a solution

    I'm having difficulty relating the two pieces of information. I have been staring at this problem for quite some time and haven't gotten anywhere. Any information would be helpful. I left out the number because I'm more interested in knowing how to solve the problem than I am getting the answer.

    Thanks

    Well what precisely are you given? You're given power per unit area, and what's power? Energy per time. Specifically, you know in an area of 1 m^2, there are xxx joules per second, which is one way to interpret that information
